Techcon EPR O-Ring, 1-3/8 Inch ID, Dispensing Valve Parts, 10 Pack

Description

This 1-3/8 inch ID EPR O-ring is one of the larger-bore dispensing valve parts used in Techcon cartridge and valve service kits where the seal diameter needs to match a bigger barrel or valve body than the smaller 9/16 or 11/16 inch sizes in the same TSD1400 family. It ships in packs of 10 for bench-level spares.

Sizing these dispensing valve parts correctly

A seal that is undersized for its bore will leak past the groove. One that is oversized can bind or compress unevenly and fail early. Confirm the exact bore diameter on the valve or cartridge adapter being serviced before ordering, since several Techcon assemblies use closely spaced o-ring sizes across a single valve family and an easy way to end up with the wrong part is going by memory instead of checking the spec sheet on file before placing the order.

Installing these dispensing valve parts

Depressurize the assembly, remove the old seal, and inspect the bore for wear grooves or debris before fitting the new EPR o-ring. EPR resists the solvents and ketones common in cleaning and flushing fluids better than a standard nitrile seal, so it is the right choice anywhere line-flush chemistry is part of the regular maintenance routine. Cycle the assembly on scrap material before returning it to production to confirm a clean seal, and record the bore size and material on the service tag so the next rebuild starts with the correct reference instead of a guess.
