Description
This Buna-N O-ring is sized for Techcon TS1400 series precision dispensing valves and is one of the dispensing valve parts a maintenance schedule calls for on a fixed interval rather than waiting for a leak. Inside diameter is 7/16 in, cross section 1/16 in, and the pack of 10 covers a full production run of valve services without a second order.
Where this size of dispensing valve parts is used
The 7/16 in bore shows up at valve body and fitting interfaces on Techcon dispensing systems handling one part and two part adhesives, sealants, and thread lockers across electronics, automotive, and general assembly work. A ring this size wears at the same rate as the rest of the seal set, so most shops replace it alongside its neighbors during a scheduled valve teardown.
Buna-N wear characteristics in this dispensing valve parts size
Buna-N (nitrile) covers a working range of about negative 40 F to 250 F and resists petroleum oils, hydraulic fluid, water, and alcohols, which suits most solvent based and oil compatible adhesive systems. Low compression set keeps the seal round under repeated valve strokes instead of taking a permanent flat spot, which is what actually causes most slow leaks rather than outright failure.
