Description
This Techcon EPR O-ring pack is dispensing valve parts stock for service work that calls for an 11/16 inch inside diameter by 1/8 inch cross-section seal. Supplied in a 10 pack, it gives maintenance teams matched spares for compatible Techcon dispensing assemblies that need EPR material rather than a general Buna replacement.
Where these dispensing valve parts fit
EPR, often grouped with EPDM sealing materials, is selected when the cleaning fluid, dispensed chemistry, or process environment is tougher on nitrile rubber. In dispensing stations, the seal does more than stop visible leakage. It helps keep air pressure and material pressure separated, keeps fluid from creeping around a bore or adaptor, and supports predictable shot size after repeated cycling. If a worn O-ring swells, flattens, or cracks, the operator may see drips, bubbles, pressure loss, or a valve that needs frequent readjustment.
Use this part when the repair list calls for TSD1400-209CPK, or when the removed seal matches the 11/16 inch ID by 1/8 inch cross-section EPR format. Do not substitute by eye. Several Techcon seals sit close together in size, and the wrong cross section can pinch during assembly or fail during the first pressure test.
Replacing dispensing valve parts with EPR
Relieve pressure, remove the old seal, and inspect the groove before installing the replacement. Clean cured residue, dust, lubricant buildup, and loose elastomer fragments from the seating area. Fit the new O-ring without twisting it, then reassemble the part squarely so the seal is compressed evenly. Cycle the station on scrap material or a controlled test before releasing production work.
