Techcon Buna-N Gasket, 2-1/8 x 1-11/16 x 1/8 Inch, Black

Description

This Techcon gasket is molded from 50A durometer Buna-N rubber in a 2-1/8 x 1-11/16 x 1/8 in profile, a replacement dispensing valve parts seal used in spool valve and spray valve housings where a worn or hardened gasket lets air or fluid bypass the seat instead of routing through the valve as designed.

Where this dispensing valve parts seal is used

Spool valves like the TS941 and spray valve bodies in the TS5500 series rely on a soft, chemically resistant gasket to hold the seal between the housing halves under repeated actuation cycles. Buna-N (nitrile rubber) resists the oils, solvents, and many of the adhesive and sealant chemistries that pass through these valves in daily use, and the 50A durometer keeps enough compliance to seal without deforming permanently under clamp load. A valve that starts leaking air at the housing seam or loses shot-to-shot consistency after thousands of cycles is often telling you the gasket has taken a permanent compression set and needs replacing before the housing hardware itself wears.

Ordering these dispensing valve parts

Replace the housing gasket at the same interval as the valve’s internal wear parts rather than waiting for a visible leak, since a gasket that has taken a compression set often still looks intact while it is no longer sealing fully. Keeping a spare on the shelf next to the valve’s seat and seal kit avoids a full line stoppage over a single low-cost part.

Valve housing and seal specifications are published in the Techcon product catalog.
