Questions about this product
- What tube sizes and thread type do these fit?
- They take 4, 6, 8, 10, and 12mm air tubing on the push-to-connect side. The other end is a female thread that screws onto male-threaded valves and cylinders. Match the tube and thread to your parts.
- Is the body brass or plastic?
- This PCF fitting uses a brass body with an O-ring seal. Brass resists corrosion and stands up to vibration and repeated use, which helps it stay leak-free in working pneumatic systems.
- What pressure can these handle?
- They're rated up to 1.0 MPa, about 10 bar or 145 psi, for compressed air. The precision O-ring keeps pressure drop low. Operating temperature runs from -5C to 60C, typical for the NBR seal.
