Right Angle Pneumatic Flow Control Valve, 1/8 NPT Male x 1/8 NPT Female Ports, 17 Flow Rating

The ports on this valve are 1/8 NPT male on one end and 1/8 NPT female on the other, so if your existing lines are already threaded to that size you can connect it straight in without any adapters. Thread sealant comes pre-applied to the threads as well, so there's no need to wrap anything with Teflon tape before you install it.

This right angle flow control valve has 1/8 NPT male and 1/8 NPT female ports. You'll need fittings appropriate for connecting your 1/8" OD nylon tubing to those NPT ports.

For pneumatic setups where you want controlled flow in one direction and free flow the other way, that is exactly what this valve is built to do. It uses a slotted adjustment so you can fine-tune the restricted direction.
