Crimp these valves to metal tubing for a permanent, leak-tight connection that doesn’t require heat or soldering. All are full port, so they do not restrict flow. Choose a crimping tool based on your valve's compatibility: Viega ProPress or Viega MegaPress.

Bronze valves resist corrosion better than brass and zinc-nickel-plated steel valves. Zinc-nickel-plated steel valves are stronger and more durable than brass and bronze valves, so they last longer. 316 stainless steel valves have excellent corrosion resistance.

Valves with EPDM rubber seals are often found in water-processing lines, fire sprinklers, and heating and cooling systems. Compared to valves with Buna-N rubber seals, these valves better handle soapy solutions and temperature fluctuations. Valves with Buna-N rubber seals stand up to water, oil, fuel, and lubricants, so they work well in fuel gas systems and air lines. They meet ANSI standards for fuel gas systems and comply with the International Fuel Gas Code.

Fix lockable lever handles in place using a padlock (not included).

Double-tee valves isolate flow between two pipe ends—no additional fittings needed. Fewer fittings in your line mean fewer leak paths to worry about.

Valves that meet ASME B31 code requirements adhere to standards for pressure piping systems.

Valves with GHT threads are compatible with any garden hose and fittings. They come in one standard size. All include a cap to protect against dirt and debris. It's connected to the valve to keep it from getting lost when the valve is in use.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

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.

For a permanent, leak-tight connection that doesn’t require heat or soldering, these valves have press-connect fittings that crimp to copper tubing. Install them with a press-connect crimping tool (sold separately). These valves meet NSF/ANSI 61 for use in drinking water systems. All are full port, so they do not restrict flow.

Valves with a threaded union are easy to install and remove without disrupting your line. They’re great for systems that need regular cleaning or maintenance. Just twist the union fitting to connect or disconnect—no need to turn the whole valve. The union fitting slides over your pipe, and the threaded fitting sits inside. The threads are galvanized steel to prevent corrosion when joining different metals, such as copper tubing to galvanized steel fittings often found on hot water heaters.

Valves with a barbed end connect to tubing with a ring and a crimping tool (both sold separately). They have multiple barbs that grip onto tubing for a secure hold.

Valves with GHT threads are compatible with all standard garden hoses and fittings. They come with a hose cap to keep dirt from entering the valve; it’s attached with a chain to keep it from getting lost when not in use.

Valves with a lockable handle can be fixed in place using a padlock (not included).

Install tee valves in your line to drain or fill your system without disassembling connections or adding fittings. They help minimize leak points.

Bronze valves are stronger and more durable than brass valves.

Valves with a check valve built in prevent backflow from entering your system.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

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.
