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 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.

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.

Insert tubing into the fittings on these valves—no heat, solder, or flux required. To withstand aggressive and corrosive solutions, they have a chemical-resistant fluoroelastomer seal and a plastic body.
Full-port valves do not restrict flow.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Precision Flow-Adjustment Valves with Barbed Fittings for Fuel
- Valve Type: Needle
- For Use With: See Table
- Seal Material: See Table
Add fine flow control to tubing lines for butane, diesel fuel, fuel oil, gasoline, kerosene, natural gas, and propane. These valves have a barbed fitting that grips onto tubing, providing a secure hold. Turn the handle to adjust flow in small increments. Valves have metal-to-metal seats that resist temperature fluctuations.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
