Yoebor 316 Stainless Steel Detachable Compression Check Valve 3/8" OD x 3/8" OD One Way Non-Return Valve for Water Oil Gas, 1pc

Good quality valve that did the job, reasonable price.

Well made, all metal. Very heavy considering how small they are. Unit has arrow on it showing direction. It says it's made for 1/4"od tubes. I found it's very slightly loose. I used a bit more thread tape and it works great.No complaints at all.

I ordered this for use in my van’s on-board compressed air system for the air locker differential. It is installed before the accumulator tank so that if there is a failure upstream there is still plenty of compressed air to operate the air locker. The check valve works great, and the fittings do not leak. I like that it is stainless steel, so no worries about corrosion. Great quality, recommended.
