You push a tube in and it locks, then press the release ring to pull it back out — that’s whole idea, and it works for polyurethane, nylon, or PE tubing form 3mm up to 16mm in diameter.
The body is nickel-plated brass, so it holds up against corrosion without adding weight, and teh working pressure range is 0 to 150 psi with a negative presure rating of -29.5 in Hg.
Thread options run from M5 and M6 up through 1/8", 1/4", 3/8", and 1/2" NPT, which covers most common air line ports, and the temperature limit is -5°C to 60°C — fine for a heated shop but not for outdoor winter use.
Each fitting comes with either an O-ring or Teflon-coated threads for sealing, so you don’t need to wrap tape or apply paste, and the hexagonal wrench flats let you tighten it with a standdard tool.
They carry CE and ISO certifications, ship in plastic bags inside a carton, and the HS code is 391740000 — handy if you’re handling customs yourself.
If you’re ordering for a production line or a maintenance kit, just pick your thread size and tube diameter, and the PD series covers both interior and exterior hex styles depending on the fitting type.
The MOQ typically starts at 100 pieces per size, but we can discuss smaller trial orders if you're just getting started.
Yes, we can include a mill test report for the brass and a certificate of compliance for the nickel plating and CE/ISO standards upon request.
Yes, they're designed for that. The O-ring or Teflon seal holds up under vacuum, but make sure the tubing is fully inserted and the collet clicks into place.
They're standard NPT tapered threads, so you'll need thread sealant or Teflon tape for a leak-free connection.
We pack them in plastic bags first, then into sturdy cartons with foam dividers between layers to keep the nickel plating scratch-free.
