Techcon TSD1400-332A O-Ring, Buna-N Valve Seal (Single Unit)

Description

The TSD1400-332A is a Buna-N O-ring built for Techcon TS1400 and TSD1400 series precision dispensing valves, and it is one of the dispensing valve parts a maintenance tech keeps on hand for a quick swap when a valve starts to seep. It ships as a single unit rather than a multi-pack, which fits a spot repair better than a full seal kit.

Where this dispensing valve parts entry fits on the bench

Techcon TS1400 and TSD1400 valves run one part and two part adhesives, sealants, encapsulants, and lubricants across electronics assembly, medical device, and general manufacturing lines. The O-ring seats at a valve body or piston interface, and a worn or nicked ring is one of the first things to check when a dispensed bead runs thin or a valve starts dribbling between cycles.

Buna-N construction across the dispensing valve parts family

Techcon uses an A suffix on this part number to mark Buna-N (nitrile) construction, consistent with sibling O-rings in the same TSD1400 line. Buna-N handles petroleum oils, hydraulic fluid, water, and alcohols well and runs from about negative 40 F to 250 F. Where the dispensed fluid is a strong ketone or aggressive solvent, the C suffix EPR version in the same family is the better material match. Either version installs the same way: seat it in the groove, check for nicks before assembly, and replace it rather than reuse it once a valve is apart for service.

Specifications

Keep one or two of these staged with your valve maintenance kit so a seep does not turn into a line stoppage. Browse the full range of dispensing valves, mixers, and nozzles for related hardware. For valve maintenance and dispensing technique walkthroughs, see Techcon.
