How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Low-Pressure Press-Connect Steel Unthreaded Pipe Fittings
- For Use On:
EPDM Rubber O-Ring: Ethylene Glycol, Propylene Glycol, Water
Buna-N Rubber O-Ring: Air, Lubricants, Propane, Fuel Oil, Natural Gas, Diesel Fuel - Specifications Met:
EPDM Rubber O-Ring: ASME B31,1, ASME B31.3, ASME B31.9, FM 1920, UL 213
Buna-N Rubber O-Ring: ASME B31.1, ASME B31.3, ASME B31.9, ANSI LC4/CSA 6.32, International Fuel Gas Code - Maximum Pressure:
EPDM Rubber O-Ring: 200 psi @ 72° F
Buna-N Rubber O-Ring: 125 psi @ 72° F - Pipe Nipples and Pipe: Use Schedule 40 Steel
- Flanges: Use Class 150 Steel
Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat. An internal gripping ring and rubber O-ring create a secure 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 steel fittings are coated in zinc-nickel to resist corrosion, but will rust if frequently exposed to saltwater or harsh chemicals. They are comparable to Viega MegaPress steel fittings.
Fittings meet ANSI/ASME B31 code requirements for use in pressure piping systems.
Fittings with an EPDM rubber O-ring are often used for water processing lines, fire sprinklers, and heating and cooling systems. EPDM rubber won’t degrade when exposed to water, ethylene glycol, and propylene glycol. These fittings meet UL 213 and FM 1920 standards for use in fire protection systems.
Buna-N rubber O-rings hold up to natural gas, propane, diesel fuel, lubricants, and other oils. Fittings with these O-rings are often used in fuel gas systems and air lines. They meet the ANSI LC4/CSA 6.32 standard for fuel gas systems and comply with the International Fuel Gas Code.
Connectors with center stop have a small internal ridge that prevents the pipe from sliding too far into the fitting. Insert the pipe on each side of the connection up to the center stop to ensure a tight seal.
Unions separate into three pieces. Unscrew and remove the center nut for quick access to a line.
Bolt two same-size flanges together with a gasket (sold separately) to create a removable connection to valves, pumps and other equipment.

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.
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.
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.
Union straight connectors separate into three pieces. Unscrew and remove the center nut for quick access to a line.
Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line.
