HVAC Angled Shut-Off Ball Valve Adapter 1/4" 5/16" SAE R22 R12 R410a

Worked to vacuum down my new mini split

good quality great safety tool

Gohantee is not a widely known brand, but makes a number of different parts in HVAC tools. When first starting out, I bought a number of different tools and adapters. The Gohantee products are not the best quality, and you need to put a little more care into making them not leak, they are good to have in the tool kit. You can see they are a little bit larger when compared to others, but the handle is easier to use.For the price, I'd keep it in the kit and maybe replace the washer to a better quality as you need to put some extra force when screwing it on to prevent it from leaking.I prefer core depressors, but shutoff valves are useful for inline use. I would consider them inline after the core depressor.

way better than not having valves on the end of your gauge set.

All 3 valves had different sized heads with different threads. Unusable.

2 out of 3 of these could not be screwed on, due to the inner brass nipple that compresses the Schrader valve sticking out way too far, not allowing the screw on surfaces to mate. Poor quality control.

Did exactly what it said it would do. Held high vacuum for 3 days with no measurable leak down.

I didn’t pay attention to these being 5/16” female connects (on two of the valves)Finding adapter to go from 5/16 male to 1/4 female is proving a pain.All the systems I’ve worked with have been 1/4 inch so four of the valve in the two set I bought are currently useless to me.

Don’t work , don’t buy

They work, just. The valve core depressor is not long enough and the plastic outer "seal" is too hard, preventing it from depressing correctly. Some modifications are needed for them to work.

Not good. Both 5/16 values leak
