Techcon TSD1400-017APK O-Ring, 11/16 in ID x 1/16 in Buna-N (Pack of 10)

Description

This Buna-N O-ring fits the larger valve body and syringe barrel interfaces on Techcon TS1400 series dispensing equipment and is one of the dispensing valve parts sized for higher volume fluid paths. Inside diameter is 11/16 in, cross section 1/16 in, and the pack of 10 keeps a production line stocked through several valve services.

Where larger dispensing valve parts like this show up

Bigger bore valves and barrels run higher flow adhesives, potting compounds, and sealants where dispense volume per cycle matters more than pinpoint bead control. The 11/16 in seal sits at the larger fittings and piston bores in that part of the Techcon lineup, and it wears on the same schedule as the smaller rings in a mixed valve fleet.

Buna-N durability for this dispensing valve parts size

Buna-N (nitrile) handles petroleum oils, hydraulic fluid, water, and alcohols across a working range of about negative 40 F to 250 F, which covers the majority of adhesive and sealant chemistries run through Techcon dispensing valves. High tensile strength and abrasion resistance matter more at this larger diameter, since a bigger ring sees more surface travel per stroke than a small one. Inspect the seating groove for nicks or debris before installing a fresh ring, and lightly lubricate it with a compatible grease to ease seating and reduce installation drag on the first few cycles.
