Review on 🔧 R1234YF Self-Sealing Can Tap for Automotive AC Charging: Left Hand Threaded, 1/2’’ Acme to 1/4’’ SAE Valve Opener by Kyle Mason

This does not fit my 1234yf (Interdynamics) gauges. The outlet thread on this valve is 1/4" FLR and the yellow hose on the gauges is 1/2" LH ACME. Nobody has the part to adjust these threads and they should be included as there is no other reason for people to buy this part separately. I ended up making my own adapter which required me to cut the tubing on my gauges and light up some copper. This valve is designed to be used with a simple inflation hose. So if you want to rebuild or vacuum out the system you can find another product unless you want to make your own adapter like I did. The glass piercing works, hence the 2 stars.
