On/Off Valves with Luer Lock Fittings
With just a half turn or a light push, these valves connect to luer lock fittings on your line. Their universal connection size fits any luer lock plug or socket.
Polycarbonate valves are lighter in weight than metal valves, but they aren’t as durable. Nickel-plated brass valves are more corrosion resistant and durable than polycarbonate valves. 303 stainless steel valves have the best corrosion resistance.
Connections without a locking ring are quicker to install and remove than those with a locking ring. Also known as luer slip connections, all they need is a light push. Add a snap-on ring (sold separately) to lock your connection in place and color code your line.
Connections with a locking ring are more secure than those without a locking ring, so they’re better for high pressures. Give the ring a half turn to lock them in place. You can’t remove the locking ring.
Barbed connections grip onto tubing for a secure hold.
