Threaded On/Off Valves with Garden Hose Outlet for Chemicals
- Valve Type: Ball
- For Use With: Air, Carbon Dioxide, Chlorinated Water, Deionized Water, Dry Material, Ethylene Glycol, Phosphoric Acid, Salt Water, Soap Solutions, Water
- Ball Material: PVC Plastic
- Seal Material: Viton® Fluoroelastomer Rubber
- Inlet Seat Material: Santoprene Rubber
- Outlet Seat Material: PTFE Plastic
Control the flow of chemical solutions from any garden hose. With a fluoroelastomer seal and polypropylene body, these valves withstand strong chemicals, such as chlorinated water and phosphoric acid. This makes them a great choice for lines used to spray greasy floors with cleaning solutions or to spread fertilizer. These valves have garden hose threads, which are a standard size, so they’re compatible with all standard garden hoses. When open, these valves don’t restrict the flow—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.
On/Off Valves with Luer Lock Fittings for Chemicals
Made of PVDF to withstand corrosive solutions, these valves are ideal for use in chemical processing. Their luer lock fittings are quick to connect and disconnect. They fit any luer lock plug or socket, thanks to their universal connection size.
Male fittings without a locking ring attach with a gentle push to create luer slip connections. For a luer lock connection, add a snap-on locking ring (sold separately). You can also use locking rings to color-code your line.
Male fittings with a locking ring connect to female fittings with a half turn. The locking ring is built into the plug body and can’t be removed.

Vacuum-Breaking Valves for Chemicals
A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals. Also known as vacuum breakers, these valves have vents that open when pressure drops to relieve vacuum conditions and prevent backward suction from drawing liquid into upstream piping.
