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.

Check Valves with Barbed Fittings for Harsh Chemicals
Prevent backflow in chemical tubing lines. These valves have barbed fittings that grip onto tubing, providing a secure hold. The plastic body and fluoroelastomer seal provide excellent chemical resistance. Valves open to allow flow in one direction and close when flow stops or reverses.
Polypropylene valves are more corrosion resistant than nylon valves.
Nylon valves are more impact resistant than polypropylene 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.

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a PTFE seal and a PVDF body. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Threads and a hex nut below the handle allow you to install these valves in instrument panels. They have a nut that can be tightened to compress the packing if it leaks.

- Needle Material: 316 Stainless Steel
For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. The 316 stainless steel body, seal and needle, and the PTFE seat and packing can withstand aggressive and corrosive solutions in chemical-processing applications. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Threads and a hex nut below the handle allow you to mount these valves in instrument panels. All have a nut that can be tightened to compress the packing if it leaks. Valves have bubble-tight soft seats that provide a tight seal when the valve is completely closed.
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.
