Frequently Asked Questions
Q: What tubing outer diameters are compatible with PK series push-in fittings?
A: The PK series push-in pneumatic fittings are available in PK4, PK6, PK8, PK10, and PK12 sizes, corresponding to tubing with outer diameters of 4mm, 6mm, 8mm, 10mm, and 12mm respectively. Always match the fitting size to your tubing's outer diameter for a secure, leak-free connection.
Q: How do I install and remove a push-in pneumatic fitting?
A: Installation is simple — just push the tubing straight into the fitting until it clicks and seats securely. To remove, press down on the release collar (collet) around the port while simultaneously pulling the tube out. No tools are required for either operation, making these fittings highly convenient for rapid assembly and reconfiguration.
Q: Are these PK fittings suitable for use with compressed air systems?
A: Yes, PK series push-in fittings are designed for standard pneumatic and compressed air applications. They are CE certified and made from durable plastic, making them suitable for typical workshop and industrial compressed air line pressures. Always verify the rated working pressure of the specific model against your system requirements before installation.
Q: Can these fittings be used for liquids or only air?
A: PK push-in fittings are primarily designed for pneumatic (compressed air) systems. While some plastic fittings can handle low-pressure water lines, it is recommended to confirm the fitting's compatibility with any fluid media before use to ensure a proper, leak-free seal.
