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

Really are necessary to purge out all the air from the lines. These work well with standard consumer grade manifold sets out there. No problem holding vacuum.

5/16” female x 1/4” male for mini splits Seem to be ok ‘!!! 🤙

Super bien, buena relacion precio y calidad, me ha servido mucho.

arrived quickly anf function perfectly

Do not buy this product. The size of the connectors is all wrong and too big. Do not waste your money. Only one in the pack was the right size.

The rubber seals are junk, buy good ones. The hoses are decent but fittings needed to be properly tightened. The valves are a bit loose as well.

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

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.

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
