Questions about this product
- What kind of tubing and air lines can I use with these fittings?
- These fittings work with pneumatic tubing that has an outer diameter of 4mm, 6mm, 8mm, 10mm, or 12mm. The threaded end uses a standard 1/8-inch NPT connection to screw into your air tools or manifolds. They are designed for compressed air and inert gases only.
- What are the maximum pressure and temperature limits for these connectors?
- You can safely run these fittings at pressures up to 10 bar, or about 145 psi. They are rated for temperatures ranging from -10°C to 60°C. Don't exceed these limits, as it can cause leaks or connection failures.
- What materials are used to make these fittings?
- The main body is made from clear polycarbonate, which resists impacts and chemicals better than nylon. Inside, a stainless steel collet grips the tubing securely, while a nitrile rubber O-ring prevents leaks.
