Yellow Jacket 19173 5/16 Female Quick Couplers x 1/4 Male Flare

Amazon didnt put this in the description but you MUST unscrew the center tit with needle nose pliers for it to be a Schrader Valve depressor *required* for pulling a vacuum on a mini-split (low-side service port with Schrader valve. If you fail to do this, you will think youre pulling a vacuum when youre not. Also remove the Schrader valve on this adapter with a remover tool as this will impede the vacuum.

Excellent product

Good product!

as advertised, seller was fast ship. thanks

Guess I did not read 5/16

Works like it should a must have for anyone who is going to be working on or installing a mini split

Ritchie Yellow Jacket is synonymous with quality, and this item is no exception. Perfect for coupling to minisplit AC units.

fast shipping and worked as designed. I hooked up my old R22 gauge set to the low side port of the min split AC.

I bought these couplers for use in installation and training on HVAC Mini Split products and know that Ritchie/Yellow Jacket are good quality products.

High quality. Just what I needed.
