TS400 cup seal Service Notes
- Replacement seal for mini spool valve repair work.
- Teflon and Viton materials support chemical resistance in many dispensing setups.
- Useful when a valve leaks, drips, or shows seal wear during teardown.
- Best ordered by exact part number to avoid installing the wrong seal size.
- Supports maintenance programs that keep common Techcon valve wear parts on hand.
Clean the fluid housing, spool assembly, and outlet block before installing replacement seals. The Techcon TS5322 user guide warns that nicks or scratches on the seal or spool surfaces can cause leakage, so avoid sharp probes and inspect sealing surfaces before reassembly.
After replacement, cycle the valve with a safe test fluid or approved purge material before returning it to production. Watch for drips at shutoff, uneven output, or pressure changes that may indicate a damaged mating surface. Keep seal changes in the service record so recurring wear can be traced to material, pressure, cleaning method, or setup conditions.
