Male Elbow Check Valve Stainless Steel - 1/4" Push-in x 1/8" MPT

Great check valve

I use the check valves in the permeate port of RO modules. They work great and less intrusive than an external check valve. The quality is very good. No issues and I have used on multiple RO systems.

A godsend

The neighborhood water with its frequent breaks mud and rust had seriously undermined our old osmosis filter. With your help I was able to replace every part that has something to do with filtering water from the membranes to this little tiny check valve. It now works perfectly and even the city has remarked that it is not leaking water through it anymore
