Description
dispensing valve parts like the Techcon TSD1400-011APK O-ring belong in service kits for adhesive and fluid dispensing equipment. This 5/16 inch ID x 1/16 inch C.S. Buna seal is a small replacement part, but it helps maintenance teams rebuild valve hardware with a known Techcon part number instead of guessing from a loose seal. Keep it with mixing nozzle, 2 part mixing nozzle, and jb weld mixing nozzle inventory so rebuild and dispensing supplies stay together.
Where dispensing valve parts Fit
Use this O-ring when a compatible valve, fitting, or fluid-control assembly calls for the TSD1400-011APK Buna size. Before installation, match the part number, material, inside diameter, and cross section against the removed seal or the equipment service list. Similar O-rings can look close on the bench while using a different material or cross section, so the SKU should drive the selection.
- Supports dispensing valve rebuilds and service carts.
- 5/16 inch ID x 1/16 inch C.S. Buna sizing helps technicians check fit before assembly.
- Ten-pack supply keeps small seals available for repeated maintenance work.
- Useful around adhesive, sealant, coating, grease, and paste dispensing stations.
Handling and Service Notes
Shut down the station, relieve pressure, and clean the surrounding parts before removing the old seal. Inspect the gland, stem, bore, and mating surfaces for scratches, cured material, chips, or swelling before the new O-ring is installed. Do not drag the seal across sharp threads. Use only lubricants, cleaners, and assembly methods approved for the equipment and fluid in service.
