Frequently Asked Questions

Q: How do I know which pneumatic fitting model to choose for my air compressor hose?

A: Match the model to your hose inner diameter (ID) and connection style. For a 6mm×4mm PU tube, choose SP10/PP10; for a 9mm barbed hose, select SH20/PH20; for 8mm×5mm PU tube, use SP20/PP20; for a male-threaded port (12.5mm), pick SM20/PM20; and for a female-threaded port (12mm), choose SF20/PF20. "S" models are socket (female coupler) and "P" models are plug (male coupler).

Q: What is the difference between a plug (P-) and a socket (S-) fitting?

A: The plug (P-series) is the male side that inserts into the socket, typically attached to the hose or tool side. The socket (S-series) is the female receiver, usually mounted on the air compressor or supply line. Together they form a complete quick-release pneumatic coupling.

Q: Are these pneumatic quick release fittings compatible with standard air compressor systems?

A: Yes. These fittings are designed to match widely used pneumatic hose and thread dimensions, making them suitable for most standard air compressor setups found in workshops, garages, and light industrial environments. Always verify the hose ID and thread size before ordering to ensure a correct fit.

Q: How many fittings are included in each order?

A: Each order includes 1 piece. If you require multiple fittings or a matching plug-and-socket pair, simply add the required quantity and select the appropriate model for each.
