Frequently Asked Questions
Q: What tubing sizes are compatible with these PD-type pneumatic fittings?
A: These push-in fittings are compatible with tubing outer diameters of 4 mm, 6 mm, 8 mm, 10 mm, and 12 mm. Available thread sizes include M5, M6, 1/8", 1/4", 3/8", and 1/2" male threads, covering a broad range of pneumatic system configurations.
Q: What materials are these pneumatic connectors made from?
A: The fitting body is constructed from brass for durability and corrosion resistance, while the push-in collet is made from high-quality plastic designed to grip and release tubing reliably with simple finger pressure.
Q: Are these fittings suitable for high-pressure compressed air systems?
A: Yes. The precision-machined brass body and CE-certified construction make these PD-type fittings well-suited for standard compressed air, vacuum, and fluid transfer lines used in industrial and workshop environments. Always verify the rated working pressure matches your system requirements before installation.
Q: How do I connect and disconnect tubing from these push-in fittings?
A: Simply push the tube straight into the fitting until you feel it lock in place — no tools needed. To disconnect, press the collet ring down toward the fitting body while pulling the tube out. The push-in quick-connect design makes installation and adjustments fast and easy.
