the SealmastertM stem seal arrangement isdesigned and constructed to prevent line fluid permeation and the resultant leakage.it consists of three components:a) Cup and cone PFe/tFe upper thrust seal.b) Cup and cone sintered 316 S/S centre load ring.c) Flat S/S tFe thrust seal.When tightened, the live load stem pulls upand compresses the stem thrust seals. As this happens, material from the upper and lower thrust seal extrude between the stem and body enclosures.the surfaces between the bottom of lowerthrust seal and top stem flange are smooth.Rotations between these two surfaces leavethe stem thrust seal “static” to create thebest possible seal. As rotation continues,components bed in and maintain theseal integrity.
