Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Compression Fittings for Stainless Steel Tubing
A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings or bite fittings. Use them in low- to medium-pressure applications.
316 stainless steel fittings have excellent corrosion resistance.
ISO and DIN fittings meet international dimensional standards.

- Specifications Met: NSF/ANSI 61
Made of moisture-resistant acetal, these fittings won't absorb water and lose strength, even in high-humidity environments. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. All meet NSF/ANSI 61 for use in drinking water systems.
