Remove the compression nut and compressionring, then put the nut and then the ring on thetube. Insert the tube end up to the fitting's tubestop. Slide the ring and the nut down to the fittingbody.

Tighten the nut using your fingers until tight.

Tighten the nut further using high quality openended or adjustable spanners. Spanner flats areincorporated into the design of Kuterlite fittingbodies. The second spanner must be used toprevent the fitting rotating as the nut is tightened.For normal joint making, tighten the nut 1 turn(360°) for fittings in sizes from 6mm to 12mm, or3⁄4 turn (270°) for fittings in sizes from 15mm to54mm. A few drops of light oil on the threads willassist, especially on sizes 35mm and above. Whenjointing stainless steel or R220 copper tube somevariation may be needed – the nut may betightened further if necessary. Take care not to overtighten the compression nut, as this will not resultin a stronger joint and could lead to problems inservice.

The following instructions illustrate just howeasy it is to make a Kuterlite joint. These coverKuterlite 600, Kuterlite 900 and waste fittingsin sizes up to and including 54mm. Details ofhow to joint large size Kuterlite 900 fittings canbe found on page 4.

PreliminariesSelect the correct size of tube and fitting for thejob. Ensure that both are clean, in good conditionand free from damage and imperfections. If thetube is oval or damaged, use a re-rounding tool.

Copper tube should be of half-hard (R250) or hard(R290) temper. Annealed soft temper tube (R220)may be jointed using Kuterlite fittings.

Preparation

Cut the tube square using a rotary tube cutterwherever possible. If a hacksaw is used to cut thetube, a fine toothed blade should be used.

Remove any burr from the inside and outside ofthe tube ends using a fine toothed file or a S120deburring tool from the XPress accessories range.

Jointing copper tubeThere are two methods of assembling a Kuterlitejoint.

Insert the tube firmly into the compressionfitting, ensuring that the compression ring seatscentrally and that the tube makes firm contact withthe tube stop in the body of the fitting.

1. Ensure the jointingsurfaces and threadsremain clean and freefrom grit.

2. If there is a slight weepfrom the joint, this willbe readily corrected bythe application of PTFEtape or a smear of anapproved jointingcompound to the sealingfaces.

3. For advice on avoidanceof stress corrosioncracking see page 19.

4. A few drops of light oilon the threads will assistthe joint makingoperation, particularly forsizes 35mm and above.

5. More torque is required to tighten the compressionnuts of 42mm and 54mmfittings, so spanners noshorter than 750mm (30")should be used.

Kuterlite fittings can beeasily dismantled andremade without the loss ofjoint efficiency, providingthe components are keptclean and undamaged. Nosealing compound is usuallyneeded to remake aKuterlite joint, but careshould be taken not to trapparticles of foreign matterwhen reassembling. Whenre-tightening the couplingnut use just enough torqueto “nip” the ring. Do notover tighten. Kuterlitefittings can replace unionfittings where an infrequentdisconnection facility isrequired.

28mm, 2" use 54mm, 21⁄2" use 67mm. For otherKuterlite sizes up to and including 42mm, the useof an imperial by metric adaptor ring (K978C) willconvert any metric compression fitting to be usedwith imperial tube. A K910IM can be used toconvert sizes 22mm, 76mm and 108mm.

Jointing PEX and PB pipe

Part 2 can be jointed using Kuterlite 600 orKuterlite 900 fittings in sizes up to 28mm. Toachieve sound joints, ensure the pipe is cut square,and is not damaged or scored in any way. Thecorrect sized pipe support liner must be fullyinserted into the PEX or PB pipe before jointingcommences. Use the appropriate liner asrecommended by the pipe manufacturer.

Jointing carbon steel and stainlesssteel tubeXPress Stainless System tube or other stainless steeltube to BS EN 10312 (formerly BS 4127), DVGW GW541; and XPress Carbon steel System tubeor other carbon steel tube to DIN 2394/ NEN 1982,can be jointed in sizes up to and including 28mmusing Kuterlite 600 or Kuterlite 900 compressionfittings. Carbon steel tubes are for use on nonpotable closed circuit systems only. To achievesound joints, the following precautions should betaken:

Ensure no flats or score marks are visible onthe outside surface of the tube. The weld beadshould not be visible.

A suitable jointing compound should be appliedto the sealing faces prior to tightening of thecompression nuts. Sealants with PTFE fillers arepreferred, with PTFE tape as an alternative.

Jointing half-hard thick walled R250copper tubeThis copper tube is significantly thicker than other varieties – refer to Table 1 on page 8 forspecifications. Special care needs to be takenduring installation. Follow steps one to threeopposite, but with the following additionalprecautions:

Ensure pipework is supported during and afterinstallation, as thick-walled copper tube is lesstolerant of stress on the joints. The pipeworkshould be clipped as close as possible to thefittings, particularly where long runs are involved.

Use spanners of the correct size and length.More torque is required to tighten Kuterlite fittingswith thick walled copper tube, and care should betaken to ensure neighbouring joints are notdisturbed.

Apply a light oil to the threads and chamferswhere possible. This will reduce assembly torqueand minimise the risk of damage. This is essentialon sizes above 28mm.

If a sealant is required, use a suitable PTFEbased compound, eg Loctite 577 or PTFE tape.

Jointing imperial copper tubeSelected Kuterlite 600 and Kuterlite 900 fittingscan be used in maintenance applications to connectcopper tube to former imperial sizes, such as BS 3931. For 3⁄8" use 12mm, 1⁄2" use 15mm, 1" use

We recommend all systemsare thoroughly tested uponcompletion. In hydraulicbased installations thesystem may be tested to 1.5 times the workingpressure of the system (seetables on page 9 for data). If higher test pressures arerequired advice should besought from YorkshireFittings.

On completion, compressedair pipeline systems must beproperly tested. The systemdesigner and installationcontractor must ensure safemethods are selected forsystem testing which willcomply with all currentHealth and Safetyregulations.

This may include testingcompressed air lines withfluids or compressed air at alimited pressure, or acombination. In any eventwe do not recommend themaximum working pressureof the product be exceededduring this procedure.

N.B. The maximumtemperature and pressurerange in any system isdictated by the componentwith the lowest performancerating.

SYSTEM TESTING

Kuterlite threaded connectorshave taper male or parallelfemale BSP threads, and themost popular sizes haveparallel male BSP threads.These are for jointingpipework to boilers, pumpsor backplate elbows. Fortaper male threads, a smallamount of inert jointingcompound or PTFE tapeshould be applied beforeinstallation. When installingparallel male threads, forexample to cisterns andcylinders, a good qualityjointing washer shouldbe used.

Jointing R220 soft copper tube.Kuterlite 600 and 900 fittings can be used to jointR220 soft copper tube in the applications in Table 1.

Using K900 fittings undergroundKuterlite 900 fittings can be used underground inconjunction with soft copper tube (R220) and an1870 Kufit adaptor. A hacksaw should be used tocut the tube – a tube cutter must not be used forthis application. All jointing surfaces must be keptclean throughout the process. Following preparationof the fitting and tube, assembly is carried out asfollows:

Slip the compression nut and compensatingring over the tube.

Flare the end of the tube using a clean K1822forming tool of the correct size by dealing a fewblows with a hammer. This operation can be madeeasier with the use of a few drops of light oil.

Insert the parallel end of the adaptor piece inthe fitting socket and locate the flared tube endonto the tapered face of the adaptor piece.

Slide the ring and the nut down to the fittingbody and first tighten by hand. Then, using spanners,tighten the nut one full turn. This is generallysufficient to provide a sound, leakproof joint.

JOINTING CHROMEPLATED COPPER TUBE

Kuterlite chrome platedfittings can be used onchrome plated copper tubewithout the need for anyadditional preparation.Assemble the joint in theusual way – refer toinstructions on page 14.

Jointing K947 and K948 reducersReducing sets can be used to convert the size of a socket in the fitting. Kuterlite K947 one-piecereducers and Kuterlite K948 reducing sets are usedas follows:

The use of a suitable PTFE based compound orPTFE tape between the fitting body and reducingset is required when assembling the reducer intothe fitting.

K947 only. Tighten the nut until sufficientforce is achieved to snap the reducer. This can beconfirmed by an audible click, which is part of thedesign and does not indicate a fault.

K948 only. Tighten the nut slowly until thetube is just prevented from rotating.

Tighten the nut a further 1⁄3 to 2⁄3 of a turn. An arrowhead stamped on the bottom of the nutprovides a reference point for this.

Only one reducing set can be used per end. Formultiple diameter reductions (eg 54mm x 28mm) or double diameter reductions (eg 35mm x 22mm),use only the correct reducing sets.

TYPE A & B FITTINGS

TYPE A COMPRESSIONFITTINGSType A, or non-manipulativefittings enable the installerto make a compression jointwithout carrying out anywork on the tube ends otherthan ensuring that they areclean, burr free, and cutsquare.

TYPE B COMPRESSIONFITTINGSType B, or manipulativefittings are used with soft(R220) copper tube andrequire the installer to flarethe tube end before thejoint is assembled.

TYPE B ADAPTORSIf soft copper is found inexisting installations, theuse of an 1870 Kufitadaptor allows conversion ofthe standard Kuterlite 900Type A fitting to a Type Bconnection. The adaptorconsists of an adaptor body,compensating ring and aDZR compression nut.

Installation underground and using reducers

The compression flange should be parallel tothe face of the body to indicate that a sound jointhas been made.

If after assembling the joint in accordance withthe instructions above a slight weep is experienced- as occasionally may happen - it will readily becorrected by the application of a smear of anapproved sealing compound to the sealing faces.

Making a large size Kuterlite 900 joint67mm to 108mm

The same preliminaries and preparation guidelinesas Kuterlite 600 and Kuterlite 900 in sizes up to54mm apply.

Place the flange and compression ring ontothe tube.

Insert the tube firmly into the compressionfitting, ensuring that the compression ring seatscentrally in the fitting body and that the tubemakes firm contact with the tube stop.

Bring up the compression flange, and tightenthe nuts by hand. Using a spanner, continue totighten the nuts diagonally in increments of 1⁄2turn, to a total minimum of 2 turns and maximumof 21⁄2 turns. DO NOT OVERTIGHTEN THE NUTS asthis may distort the flange or shear the nuts.
