Techcon Air Hose Connector Assembly, 4mm

Description

The Techcon A0100478 is an air hose connector assembly built for Techcon’s TS Series pneumatic dispensing valves. It carries actuation air from a digital controller such as the TS350 or TS355 into the valve’s air inlet port, and it ranks among the dispenser parts most shops keep on hand because the tubing and quick connect fitting take the most flex and connect and disconnect cycles of any component in the air circuit. The assembly terminates in a black male quick connect fitting on 4mm OD tubing, matching the factory installed line found on Techcon’s diaphragm, spool, spray, and needle valve families.

Where These Dispenser Parts Fit in a Techcon Air System

A Techcon dispensing setup runs on regulated shop air from end to end. The controller (TS350 and TS355 units run 0 to 100 psi and 0 to 15 psi respectively) meters that air on a timed or pressure controlled cycle and sends it down a hose to the valve’s air inlet port, a 10-32 UNF connection on most TS5000 series bodies. The A0100478 assembly is that connection: hose on one end, quick connect fitting on the other, sized to snap onto the valve without a wrench. The same style of connector shows up in the spare parts list for the TS5620 and TS5621 diaphragm valves, the TS5322 and TS5322D mini spool valves, and other air operated valves in the line, along with pressure pots and manifolds that share the same shop air supply. For the full lineup of valves, controllers, and pressure equipment this connector serves, see the Techcon product catalog.

Pressure Rating and Build on This Dispenser Parts Connector

Techcon’s air operated valves need a minimum of 70 psi (4.8 bar) at the air inlet to actuate reliably, and the broader TS5000 line is built around a 100 psi (6.9 bar) ceiling, the same limit stamped on the TS5322D and matched by the TS350 controller’s 0 to 100 psi range. The A0100478 assembly is rated to that 100 psi ceiling, so it holds the working range a shop actually runs without becoming the weak point in the circuit. Construction is a nylon quick connect fitting on a flexible hose, sized to the 4mm OD used across Techcon’s compact valve bodies. Because this line carries air rather than fluid, keep it free of kinks and clear of hot surfaces or sharp edges near the valve mount, and replace it at the first sign of a soft spot or a leak at the fitting rather than waiting for a full disconnect mid run.

This connector pairs naturally with the tips, adaptors, and mixing nozzles that round out a Techcon dispensing setup, and it’s worth keeping a spare on hand since hose and fitting wear is normal on any shop air line that sees daily cycles.
