Pneumatic Quick Joint
The PC Series connects pneumatic tubing straight into a threaded port — cylinders, solenoid valves, air preparation units, anywhere a tube needs to meet a threaded connection point without a bend. Push the tube in and it seals immediately; press the release ring to pull it back out. It comes in tube sizes from 4mm to 16mm (Φ4–Φ16) and thread options from M5 to R1/2, covering most standard pneumatic ports.
- Product Introduction


he Problem With Threaded-Only Connections
Wrenching a tube fitting into place, wrapping thread tape, checking for leaks, wrenching it again - that's the old way, and on a machine with dozens of connection points, it adds up fast. It also means every retube or maintenance pass repeats the same slow process.
The PC Series cuts that down to two steps: push the tube in, and it's sealed. When you need to swap or service the line, press the release ring and the tube comes free - no tools either direction. On equipment where air circuit reliability affects uptime, that speed difference during both initial build and later maintenance is the actual point of the fitting, not just a convenience feature.
Straight-Line Connection, Compact Footprint
Unlike an elbow fitting, the PC Series keeps the tube running in a straight line from the port. That's the right choice when you don't need to change direction - it keeps the connection point small and avoids adding a bend where one isn't needed, which helps keep tube routing simple in tightly packed control
cabinets and cylinder banks.
Sealing and Build Quality
The seal comes from the collet and O-ring at the push-in end, backed by the thread connection at the port. If you need pressure ratings, temperature range, or cycle-test data for a spec sheet or RFQ, ask us for the datasheet - we'd rather send you real test numbers than describe the seal in adjectives.

Frequently Asked Questions
How is the PC Series different from an elbow fitting?
Same push-in connection and sealing method - the PC Series keeps the tube in a straight line instead of redirecting it 90°. Use it wherever you don't need to change tube direction.
What tubing works with the PC Series?
PU or PA pneumatic tubing, OD 4mm to 16mm, matched to the fitting's rated size.
How do I remove the tube?
Press the release ring around the push-in end and pull the tube out. No tools required.
What's the MOQ, and can you do custom threads or tube sizes?
Send your volume and specs and we'll confirm MOQ, lead time, and whether a custom configuration is feasible.
Do you offer OEM branding or private labeling?
Yes - contact us with your requirements for a quote.
