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 comply with the Uniform Plumbing Code for plumbing systems and the Uniform Mechanical Code for HVAC and refrigeration. They also meet ANSI/ASME B31 code requirements for use in pressure piping systems.

304 stainless steel fittings resist corrosion from frequent exposure to water and fuels. They are often used for water processing lines, heating and cooling systems, and fuel lines.

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.

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