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. These fittings are comparable to Viega MegaPress fittings.
Fittings meet ANSI/ASME B31 code requirements for use in pressure piping systems.
316 stainless steel fittings stand up to harsh environments with constant exposure to chemical solutions. They meet NSF/ANSI Standard 61 for use with drinking water, and are often found on water and chemical processing lines in corrosive environments.
