On/Off Valves with Press-Connect Fittings for Drinking Water
- Valve Type: Ball
- For Use With: Drinking Water
- Seal Material: EPDM Rubber
- Specifications Met: NSF/ANSI 61
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 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).
Bronze valves are stronger and more durable than brass valves.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

On/Off Valves with Press-Connect Fittings
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.
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.
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 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.

Gradual On/Off Valves with Press-Connect Fittings
- Valve Type: Gate
- For Use With: Water
- Specifications Met: MSS-SP-80
For a leak-tight connection, crimp the press-connect fittings on these valves to metal tubing with a crimping tool (not included)—no heat or soldering required. The fittings are comparable to Viega fittings. These valves open and close gradually as the wheel handle turns, preventing sudden starts and stops of flow. They’re also known as gate valves. Made of bronze, they have good corrosion resistance.
Valves with a nonrising stem keep the handle in the same position whether they’re open or closed. They’re often used in low-clearance locations.
Valves with a rising stem lift up the handle as they open and lower it as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem.
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.

Gradual On/Off Valves with Press-Connect Fittings for Drinking Water
- Valve Type: Gate
- For Use With: Drinking Water
- Specifications Met: NSF/ANSI 61
For a leak-tight connection in drinking water lines without heat or soldering, crimp the fittings on these valves to metal tubing with a press-connect crimping tool (sold separately). The fittings are comparable to Viega fittings. Also known as gate valves, they open and close gradually to prevent damage to your system from sudden changes in flow. Safe for use in drinking water systems, these valves meet NSF/ANSI 61. They have good corrosion resistance since they’re made of bronze.
Valves with nonrising stems fit well underground and in other low-clearance places since the handle doesn’t move up when the valve opens.
Valves with rising stems let you see at a glance whether flow is on or off. The handle rises as the valve opens and lowers as it closes. The stem stays separate from the material flowing through your line, reducing corrosion so they last longer than valves with nonrising stems. With a long lifespan, you can use them for critical lines and lines that need to be opened and closed frequently.
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.
