Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat. Fittings have an internal stainless steel gripping ring and rubber O-ring that create a seal when crimped. They are designed to leak if fittings have not been crimped; a colored dot marks the leak path so it's easy to spot unsealed connections. All of these fittings are made of 304 stainless steel to resist corrosion from frequent exposure to water and fuels. They’re often used for water processing lines, heating and cooling systems, and fuel lines. They are comparable to Viega MegaPress fittings.

Fittings meet ANSI/ASME B31 code requirements for use in pressure piping systems.

Connectors with center stop have a small internal ridge that prevents the pipe from sliding too far into the fitting and taking space from the pipe on the other side. Insert the pipe on each side of the connection up to the center stop to ensure a reliable seal.

Straight union connectors separate into three pieces. Unscrew and remove the center nut for quick access to a line.
