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.
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.
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.

Inline tees are also known as branch tees.
Crimping tools seal fittings in less than five seconds. These tools are cordless, so you can take them to any job. Connect the jaw or ring that matches your pipe size to these tools, then pull the trigger to crimp the fitting. The pivoting head lets you access connections from any angle.

Jaw and ring sets include three jaws, three rings, and one ring actuator jaw. Jaws are for pipe sizes 1/2 to 1; they fit directly into the crimping tool. Rings are for pipe sizes 1 1/4 to 2; clip the ring around the fitting and use the ring actuator jaw and crimping tool to press the open ends together.

Nickel-Plated Brass Compression Fittings for Copper Tubing
- For Use With: Air, Cutting Oil, Diesel Fuel, Ethyl Alcohol, Fuel Oil, Gasoline, Hydraulic Fluid, Isopropyl Alcohol, Lubricants, Mineral Oil, Natural Gas, Steam, Water
- Temperature Range: -75° to 550° F, except 90° elbow adapters with BSPP threads are 0° to 170° F
- Tubing: Use with copper
- Specifications Met: DIN 3861, except nuts meet DIN 3870
With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings. They have a single sleeve (ferrule) made of plain brass that gently bites into copper tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. These fittings are also known as flareless fittings. All meet DIN standards for tube fitting dimensions.
