Threaded On/Off Valves with Garden Hose Outlet
- Valve Type: Ball
- For Use With:
Brass Body: Water, Air, Helium, Butane, Ethanol, Ethylene Glycol, Gasoline, Kerosene, Mineral Spirits, Natural Gas, Propane, Soap Solutions, Methanol
Nickel-Plated Brass Body: Water, Air, Helium, Butane, Ethanol, Ethylene Glycol, Gasoline, Kerosene, Mineral Spirits, Natural Gas, Propane, Soap Solutions, Isopropyl Alcohol
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.
Nickel-plated brass valves stand up to corrosion better than plain brass valves. They have a fluoroelastomer seal that withstands chemicals and temperature fluctuations, making them a good choice for lines flushed with hot fluids or cleaners.
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.

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.
Valves with a barbed inlet make quick connections to unthreaded hose and tubing.
Valves with a socket-connect inlet bond to unthreaded pipe with primer and cement (both not included) to create a permanent, leak-tight connection. The connection is stronger than that of threaded or barbed connections.
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 Flow-Adjustment Valves with Garden Hose Outlet
- For Use With: Oil, Water
- Valve Type: Globe
These valves have an NPT inlet and a GHT outlet for attaching garden hose. They gradually open and close with multiple turns of the wheel handle to adjust and regulate flow. All have a nonrising stem that stays in the same position whether the valve is open or closed.
Lockouts (sold separately) thread over the valve outlet and lock in place with a padlock (not included) to prevent unauthorized water use.

Vacuum-Breaking Valves with Garden-Hose Fittings
- For Use With: Air, Water
- Seal Material: Rubber
Prevent dirty, contaminated water from backing up into your garden hose line—install these valves between a faucet and a garden hose. Also known as vacuum breakers, these valves have a built-in check valve that blocks backflow, so you can leave your hose in a utility sink full of dirty water without the water going back into the line.
When the check valve is closed, it has vents that open to release the water. This reduces pressure in the line and confirms the valve is working. Because these valves vent water, use them in environments where spilled water won’t cause a problem. This design adheres to ASSE Standard 1011 for valves with a vent.
Mount valves to faucet outlets with a set screw, and easily thread or unthread a hose while the valves stay in place.
Valves comply with Uniform Plumbing Code (UPC) and are CSA certified, so they're safe to use in sanitary plumbing systems because they prevent contamination from flowing backward into your line.
These valves are designed to be used intermittently. They've been tested under ASME A112.1.3, which assumes the valves will not be used for more than 12 hours at a time.
Chrome-plated brass valves are more corrosion resistant than plain brass valves.
Valves with tamper-resistant set screws have a head that breaks off after tightening to prevent valve removal after installation.
Valves that meet NSF/ANSI Standard 372 are certified lead free.

Quick-Disconnect Garden Hose Couplings
Use these couplings if you need frequent access to a garden hose line—a complete coupling consists of a plug and a socket that connect and disconnect quickly. The compact design makes these couplings sleeker and easier to handle than cam-and-groove garden hose couplings. Couplings have a sleeve-lock socket. Connect by sliding back the sleeve on the socket, inserting the plug, and releasing the sleeve. To disconnect, slide the sleeve back and pull out the plug.
Brass couplings have good corrosion resistance and are softer than 303 stainless steel couplings, so they’re easier to thread together. ABS plastic couplings offer comparable corrosion resistance to 303 stainless steel couplings, but are lighter in weight.
Couplings with shut-off valve have a valve in the socket that stops the flow of water when the coupling is separated.

On/Off Valves with Garden Hose Threads
Start and stop the flow of water through your garden hose.
Plastic valves are lighter in weight than metal valves, but they’re typically not as durable. Zinc valves are stronger and more resistant to wear and tear than plastic valves. Brass valves are stronger and resist corrosion better than plastic, zinc, and aluminum valves. Aluminum valves resist the highest pressures. TPR-coated valves stay safe to touch because they won’t get too hot in the summer or too cold in the winter.
Valves with a toggle switch are easy to use one-handed because you can flip the water on or off with just your thumb. Valves with a contoured lever handle are easy to grip, even if they're wet, oily, or you're wearing gloves.
Add kink absorbers to eliminate sharp bends between your hose and your valve, maximizing flow and preventing damage.
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.

Swivel On/Off Valves with Garden Hose Threads
- Valve Type: Ball
- For Use With: Water
- Temperature Range: 35° to 120° F
Keep fluids flowing—these valves twist and turn to prevent your hose from kinking. They connect to your faucet and swivel 360°, which makes it less likely your hose will kink when you move it side to side. Their lever handle is easy to turn, and lets you know if the valve is open or closed at a glance.
Zinc valves have good corrosion resistance. A plastic coating protects your hands by keeping the valve’s surface from getting too hot or cold.
Brass valves are more durable and corrosion resistant than zinc valves.
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.
Add a kink absorber for additional protection to your hose. Connected between the valve and the hose, they prevent kinking from sharp up and down movements.
