Frequently Asked Questions

Q: What tube sizes are compatible with these push-in pneumatic fittings?

A: These nickel-plated copper push-in fittings are available for pneumatic tubing with an outer diameter (OD) of 4mm, 6mm, 8mm, and 10mm, covering the most common pneumatic hose sizes used in workshops and industrial settings.

Q: Are these fittings compatible with PU (polyurethane) air hose tubing?

A: Yes, the PU-series straight push-in fittings are specifically designed for use with PU (polyurethane), nylon, and similar flexible pneumatic tubing, providing a secure and leak-free air-tight connection.

Q: Why choose nickel-plated copper fittings over standard brass or plastic fittings?

A: The all-copper core provides excellent strength and thermal conductivity, while the nickel plating adds a layer of corrosion and oxidation resistance. This combination makes these fittings more durable and longer-lasting than standard brass or plastic alternatives, especially in humid or demanding environments.

Q: Do these fittings require tools for installation?

A: No tools are required. Simply push your pneumatic tubing into the fitting until it clicks into place for an immediate, secure connection. To release, press the collet collar and pull the tube free.
