TAILONZ PNEUMATIC Elbow and Straight Combination 3/8 Inch Tube OD x 1/4 Inch NPT Thread Push to Connect Fittings PC-3/8-N2+PL-3/8-N2(Pack of 12)

This was a good value, but wasn't what I needed. I was actually needing a 1/4 x 1/8 to work on my truck airbags. I did end up ordering the correct size on Amazon and it worked great. Keeping these just in case I need them in the future.

and it says so in the description, I just missed it, so it will not work for 1/2 pex. but it came fast and with the correct # of items.

These work great! I needed them in addition to pvc piping kit for my new air compressor set up. Very happy with the purchase.

I used these for a project with compressed air. Quality of fittings was excellent. No issues with fit or function. Very happy with the price, value and delivery.

This us exactly what I needed. Other plastic ones gave me leaks

SO far so good. No leaks

These are great, Im using them in a harsh machining environment for both air and coolant, so far they hold 100psi all day no problem! Zero leaks

Nice product. Worked well.
