Description
This Buna O-ring is one of the dispensing valve parts sized to fit Techcon TS1400 series precision dispensing valves. The Buna-N (nitrile) compound is the standard general purpose seal for structural adhesives, epoxies, and silicones, offering good compression set resistance at a lower cost than specialty elastomers. Selecting the correct elastomer keeps the valve sealing consistently shot after shot instead of leaking or dripping between cycles.
Where Dispensing Valve Parts Like This Are Used
- Seal replacement inside Techcon TS1400 series precision dispensing valves during scheduled maintenance
- Valve rebuilds on automated and semi-automated adhesive dispensing lines
- Production runs where Buna seals are the correct material match for the dispensed fluid
- Electronics assembly, medical device bonding, and other precision dispensing work where drip control matters
Valve seals wear from the same repeated open close cycling that makes precision dispensing possible in the first place. A worn or degraded O-ring lets fluid weep past the seat, changing shot size and leaving residue on the nozzle tip. Swapping this seal as part of a rebuild restores the original shot-to-shot consistency without replacing the whole valve body.
Dispensing Valve Parts Specifications

- Cross section: 3/32 in.
- Material: Buna
- Fit: Techcon TS1400 series precision dispensing valve
- Pack quantity: 10 O-rings
Order this Buna seal by the pack of 10 to keep a full rebuild set on hand, since valve seals are best replaced as a set rather than one at a time. Replace all O-rings in the valve body together during a rebuild rather than spot-swapping just this one. Keep spares on the shelf for planned changeouts instead of waiting on a mid-run failure to shut down the line. Browse the dispensing valve and nozzle catalog for compatible components, or see Techcon for the full TS1400 valve lineup.
