It’s used to assembling
Engine application
It s used to assemblingtwo plastic components, typical application is for
air filter.
U ll li d f i ti i tIt’s used to enhance plastic
parts.The flange allow to protect
plastic with the metal screwcontact .
Applications: loioil filters, cam
Usually applied for inserting intoplastic where high torque isrequired
Applications: loioil filters, camcovers, air intake man. etc,.
Normally applied toenhance plastic applications and toavoid contact betweensteel screw and plastic.pApplication: camcovers, oil filters.
Used to enhanceplastic parts and in
same time to maintainconstant gas pressure
on the application withthe help of o-rings.
New generation product whichjoins the screw function withthat of the spacer oneIt is usually employed on cover tappet and carters .
p gf.e. Application: cam
cover.Used where enhance for plastic requirements are demanded and allow also the assembling ofmultiple components in same time.
