AirTAC Pneumatic Fittings Series
One-Touch Push-In | Stop Valve | Metal Lock-Nut
Product Features
General Fittings (Standard APC/APL Series)
- Highly compact design with a vast array of shapes (Straight, Elbow, T, Y, Multi-way Manifold) to suit any complex pneumatic piping layout.
- Available in high-strength plastic and robust metal construction options.
- Ensures reliable sealing with effortless, one-touch tube insertion and release.
One-way Function Fittings (ASPC / ASPL Series)
- Highly recommended for locations where pneumatic tubing needs to be frequently disconnected and changed.
- Auto-Stop: The moment the tube is pulled out, the internal valve instantly closes to stop air leakage.
- Auto-Flow: Once a tube is securely inserted, the internal valve opens automatically to allow air flow.
Check Valve Fittings (APCVC Series)
- Functions as a non-return valve, allowing compressed air to flow in one direction only and completely blocking reverse flow.
- Helps maintain constant output pressure in critical circuit segments.
- Features an exceptionally low opening pressure (0.1 kgf/cm²), making it suitable for low-pressure actuation.
