R410A Adapter 5/16" SAE Female to 1/4" SAE Male Flare for Air Conditioners HVAC, 2 Adapter (1 Straight + 1 Angled)

Must have!!!!

Great price and quality. Came with new seals you must install. Would purchase again

Product worked great for adapting an older set of gauges to a Mini Split system. Specifically a Senville 48k Ducted split. Very self explanatory product with different options for different angles.

Based on what others have said, and the design itself, I went ahead and modified it before using it, aannnnddd (drum roll please), IT WORKED GREAT.On one of the short ones, and one of the long ones, I replaced the Teflon (white) seal with the included softer seal. But, based on the way the male end was affixed to the tube, I still didn't trust it to seal: it is not soldered on -- appears to just be pushed into place. SO, again, before even using it, I went ahead and put some anerobic-curing post-assembly sealant* between the tube and the male fitting. I put it on the outside, and it wicked down into the joint. You can see in the attached photo where I put it. END RESULT: When I did use it to evacuate a system, the vacuum held for about 20 minutes with no indication of leakage (the vacuum gage didn't budge over the 20 minutes, nor when I turned the pump on again at the end of the 20 minutes.)I wish they had just provided the 8 seals as part of the kit, without installing the 4 Teflon ones. The seals are EXTREMELY difficult to remove. The only way I could get the Teflon seal out was to use an Exacto knife to cut completely through the seal (from bottom to top -- risking putting a scar/leakage path in the brass), then to pry one of the edges away from the brass enough to wriggle some needle-nose pliers between the brass and the Teflon. It was a major pain-in-the-hand (I ended up injuring my finger with a sharp instrument -- recommend holding it with pliers while wrestling with it)! Once I got the Teflon seal out, installing the soft seal was easy: just pushed it in with my (uninjured) fingers.*Permatex Threadlocker GREEN, Penetrating Grade 29000 or LocTite equivalent.

Excellent ext tool!👍👍👍

Used to get gauge on mini-split connector. Mini-splits use different size ports than normal HVAC gauges support.

Awesome Purchase

Let's just say this.... the seals were useful. Really lousy. Straight out of a gumball machine
