Smallest Check Valve in the World

Our 1/8" (3.2mm) plain tube check valve is the smallest spring assisted valve in the World.

It's difficult to understand how a check valve with an OD of just 1/8" and a length of 25mm exists, but it's not difficult to understand how useful it is. Our patented check valve technology allows us to fit a reliable and precise ultra-miniature check valve into a plain tube format that is perfect for applications where space is an issue. Just be careful not to lose it!

The standard model, available to buy online, comes in 316 stainless steel with a cracking pressure of 0.6 bar.
