Metal Garden Hose Fittings
Connect these fittings to rubber or plastic garden hose for a variety of water supply applications.
Brass fittings have good corrosion resistance and are softer than other metal fittings, so they’re easier to thread together. 303 Stainless steel fittings have very good corrosion resistance, so they’re the best choice for high-humidity environments.
Fittings that swivel until tightened rotate 360° for easy installation.

Metal Garden Hose Fittings for Drinking Water
These fittings meet NSF/ANSI Standard 61 for drinking water. Connect them to rubber or plastic garden hose for a variety of water supply applications. Fittings are brass for good corrosion resistance.
Plastic Garden Hose Fittings
Made of nylon, these fittings are lighter in weight than metal garden hose fittings. They have excellent impact and abrasion resistance and good corrosion resistance. Connect them to plastic or rubber garden hose for a variety of water supply applications.
Plastic Threaded On/Off Valves with Garden Hose Threads
- Valve Type: Ball
- For Use With: Air, Water
- Seat Material:
NPT Male × GHT Male: Buna-N Rubber
Socket Female × GHT Male: Buna-N Rubber
All Other Valves: PTFE Plastic
Control flow through any garden hose—the threads on these valves are universally compatible with garden hose connections. Made of PVC, they’re a lightweight and corrosion resistant alternative to metal valves. A Buna-N rubber seal gives them good resistance to water and oil. The threaded connections on these valves let you take apart and reassemble your setup as needed for maintenance.
Full-port valves have a wider bore than standard-port valves, so they won’t 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.

Threaded On/Off Valves with Garden Hose Outlet

- Valve Type: Ball
- For Use With: Water, Air, Helium, Butane, Ethanol, Ethylene Glycol, Gasoline, Kerosene, Mineral Spirits, Natural Gas, Propane, Soap Solutions, Methanol
Turn the flow to any garden hose on and off. These valves have garden hose threads, which are a standard size, so they're universally compatible with all standard garden hoses. They do not restrict flow when open—they’re full port.
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.

Threaded On/Off Valves with Gauge Port and Strainer


- Valve Type: Ball
- For Use With: Oil, Water
- Seal Material: PTFE Plastic
Monitor and maintain flow quality from a single valve—these valves have a gauge port, strainer, and drain built in. A gauge port gives you a spot to add a gauge to monitor pressure without stopping flow. The strainer traps debris to prevent blockages, while the drain releases excess liquid and debris. They’re a good choice for lines that require frequent maintenance or cleaning. A threaded union makes these valves easy to install and remove without disrupting your line. They thread together or apart with only a turn to the union fitting, unlike other threaded on/off valves that require repositioning your pipe or valve. The union fitting slides over your pipe, and the threaded fitting sits inside. These valves are full port, so they do not restrict flow.

Threaded On/Off Valves
Use these valves in general purpose applications, such as those with water, oil, air, and inert gas.
Brass valves have good corrosion resistance to air, water, and oil. 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.

Single-Flange On/Off Valves

Bolt these valves to pipe and pump flanges to start and stop flow before pump maintenance without draining your system. They attach to industry-standard two-bolt flanges on circulation pumps from manufacturers such as Bell and Gossett, Taco, Grundfos, and Armstrong. All are full port, so they do not restrict flow.
Valves with T-handles resist accidental movement when bumped or snagged.
Valves with 1/2" dia. bolt holes fit standard pumps. Valves with 5/8" lg. x 1/2" wd. bolt holes fit both standard and high-velocity pumps.

Solder-Connect On/Off Valves with Gauge Port and Strainer


- Valve Type: Ball
- For Use With: Oil, Water
- Seal Material: PTFE Plastic
- Specifications Met: ASME B16.22
Monitor and maintain flow quality from a single valve. These valves have gauge ports, a strainer, and a drain built in. Gauge ports let you take pressure, temperature, and other measurements in your line. A strainer traps debris to keep it out of your system, and a drain lets you release fluid and debris. These valves are full port, so they do not restrict flow.
Thanks to their solder-connect union fitting, these valves are especially useful in lines that require frequent maintenance and cleaning. Slide the union nut on the tube and solder the solder-connect fittings to your line for a permanent, leak-tight connection. You can then connect and disconnect the line with a turn of the union fitting.
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.
