Product Introduction
Pneumatic Quick Connect – PC, PL, PU, PY, and PE Series Push‑in Fittings was born out of a simple observation: pneumatic systems are only as good as their connections, and traditional threaded fittings are slow, fiddly, and prone to leaks if you don't get the tape just right.
So we designed a range of push‑in fittings that solve that problem. The body is nickel‑plated brass – not because it's the cheapest option, but because it holds up in real workshop conditions where humidity, oil mist, and temperature swings are part of daily life. The locking claw is stainless steel, and it grips the tube firmly without crushing it. The release ring is engineered to depress evenly, so you don't have to fight it when you need to make a change.
Whether you're building a new machine, replacing a failed fitting, or rerouting a line during maintenance, these fittings do one thing well: they get you connected and back to work. That's the whole point.
【Feature】– What you actually get
The range covers the five configurations that handle almost every pneumatic circuit requirement:
PC Series – Straight male connector. Tube goes in one end, thread goes into the port. Sizes from M5 up to G1/2, tube OD from 4mm to 16mm.
PL Series – Elbow male connector. Same sizes as PC, but turns the corner 90°. Useful when you're routing tubing in tight spaces.
PU Series – Straight union. Tube‑to‑tube connection. When you need to join two lengths of tubing without a threaded port.
PY Series – Y‑connector. Splits one flow into two. Tube OD from 4mm to 12mm.
PE Series – T‑connector. Branches flow at 90°. Same size range as PY.
All of them work with PU, PA, PE, and PVC tubing. Working pressure is 0 to 1.0 MPa, proof pressure is 2.5 MPa, and the operating temperature range is 0°C to 60°C. Nothing exotic – just solid, reliable numbers that cover the vast majority of industrial pneumatic applications.

FAQ
1. What are pneumatic quick connect fittings used for?
They are used for fast, tool-free connection and disconnection of pneumatic tubing in compressed air systems – saving time during assembly, maintenance, and system modification.
2. What is the difference between PC, PL, PU, PY, and PE series?
PC is a straight male connector, PL is an elbow male connector, PU is a straight union for tube-to-tube connections, PY is a Y-shaped connector for splitting flow, and PE is a T-shaped connector for branching flow.
3. What tubing is compatible with these fittings?
They are compatible with PU (polyurethane), PA (nylon), PE (polyethylene), and PVC tubing.
4. What is the working pressure range?
The working pressure range is 0 to 1.0 MPa, with a proof pressure of 2.5 MPa.
5. Do these fittings require tools for installation
No. These are push-in fittings – simply push the tube in to connect and press the release ring to disconnect. No tools required.
6. What sizes are available?
Thread sizes include M5, G1/8, G1/4, G3/8, and G1/2. Tube outside diameters range from 4mm to 16mm.
