Techcon TS5440 Microshot Needle Valve Seal Kit

Description

The Techcon TS5440 seal kit supplies the fluid-side dispensing valve parts used to refresh seals in a TS5440 Microshot needle valve. It is the right service item when the valve body and needle assembly remain usable, but O-rings, washers, or seal interfaces are worn enough to affect shutoff, deposit shape, or material control.

Where dispensing valve parts fit

The TS5440 Microshot valve is built for precise deposits of low to medium viscosity fluids. Its normally closed needle and seat design uses external stroke control so technicians can tune deposit size for small beads, dots, and micro deposits. Seal wear often appears as weeping after the dispense signal, air or fluid leakage near the body, or a drift in deposit repeatability that cannot be corrected with controller timing alone. Replacing the seal kit lets maintenance restore the wetted section without changing the whole valve.

Seal kit contents and handling

The seal kit includes the fluid inlet fitting, cup seal fitting, O-rings, Mylar washer, nylon washer, and related sealing pieces called out for TS5440 service. Clean the valve thoroughly before disassembly, keep new seals away from cured adhesive flakes, and use the lubricant specified for O-rings and seals during reassembly. The dry seal components should stay dry when the guide requires it. Keep cartridge consumables such as mixing nozzle, 2 part mixing nozzle, and jb weld mixing nozzle inventory in a different bin so service kits remain organized by valve family and technicians can find the right TS5440 parts quickly.

Ordering dispensing valve parts

Choose this kit for routine TS5440 seal service or as a spare for production cells that depend on a Microshot valve for repeatable deposits. If the needle, piston, or body is damaged, pair the seal kit with the matching replacement assembly rather than expecting seals alone to correct mechanical wear. For related service kits, valves, tubing, and dispensing accessories, browse dispensers, mixers, and nozzles. Manufacturer background is available from Techcon.
