Description
The Techcon EPR O-ring is a small dispensing valve parts replacement for fluid-control assemblies that need a 0.489 inch inside diameter by 0.070 inch cross-section seal. The 10-count pack supports maintenance work where a worn or swollen O-ring can cause air leakage, fluid bypass, or inconsistent shutoff in a dispensing station.
Where these dispensing valve parts fit
O-rings sit inside valves, fittings, and small fluid-path hardware where two surfaces need a repeatable seal. In adhesive and sealant dispensing, a seal that looks minor can have an outsized effect on shot consistency. If the O-ring hardens, tears, flattens, or takes a compression set, the operator may see delayed starts, tailing, bubbles, or material around a joint that should stay dry.
This EPR seal size is best handled as an exact replacement part. Match both dimensions before releasing it to maintenance, since a close-looking O-ring can still be wrong if the cross section is off. The 0.489 inch ID locates the seal on the mating feature, while the 0.070 inch cross section provides the squeeze needed for sealing. Keep the package label with the rebuild kit so the size does not get mixed with nearby metric seals.
How these dispensing valve parts support maintenance
Replace seals during a planned rebuild rather than waiting for a valve to fail in production. Clean the groove, inspect the mating metal or plastic for scoring, and avoid sharp tools that can nick the replacement seal during installation. Lubrication and chemical compatibility should follow the valve or fluid-system instructions for the exact equipment in use. After the rebuild, test the station with the intended fluid or an approved setup material before returning it to production.
