One Way Check Valve – Female In – 1/4″ BSP Male to 1/4″ BSP Female

This is a one way check valve that allows air to pass through in one direction only.

A great application is air from compressor into tank – when the compressor is off it can prevent air leaking back out through the compressor.

This has 1/4″ BSPT threads – both male and female.

Air is permitted to flow in through the female side and out through the male.

At AAA we stock the following check valves ….

• 1/4″ BSPT Female In (Male Out)
• 1/4″ BSPT Male In (Female Out)
• 1/8″ BSPT Female In (Male Out)
• 1/8″ BSPT Male In (Female Out)

When making threaded connections we recommend using a liquid thread sealant on all threads. Plumbers tape can create leaks later on when bits of tape get stuck in valves.
