Frequently Asked Questions

Q: What pipe sizes does this 304 stainless steel tee fitting support?

A: This double ferrule tee fitting supports stainless steel pipe outer diameters of 3 mm, 4 mm, 6 mm, 8 mm, 10 mm, and 12 mm in metric sizes, as well as 1/8", 1/4", 3/8", and 1/2" in imperial sizes. Be sure to match your tubing's outer diameter (OD) when ordering.

Q: What is a double ferrule compression fitting and why is it better?

A: A double ferrule (two-ring) compression fitting uses both a front ferrule and a back ferrule to grip and seal tubing. This two-piece system creates a stronger, more vibration-resistant, and leak-free connection compared to single ferrule designs — making it ideal for high-pressure gas, oil, and water lines up to 16 MPa.

Q: Is this fitting suitable for high-temperature applications?

A: Yes. This 304 SS tee connector is rated for operating temperatures up to 450°C, making it suitable for a wide range of industrial, hydraulic, and instrumentation applications where elevated temperatures are a factor.

Q: How do I install this tee fitting?

A: Simply insert your stainless steel tubing into each port of the tee fitting and tighten the hexagon nut with a wrench. The double ferrule design compresses around the tube OD to form a secure, leak-tight seal. No soldering or special tools are required beyond a standard wrench.
