R134A R410A R22 R12 Charging Hoses and Ball Valve Set, 3 Pcs Color Coded Hoses/w Ball Valve 1/4" SAE Thread (7" Long) for AC HVAC Maintenance Kit and Air Condition Refrigeration Charging Tools

Excelente

these are great for r12 shut off hoses but they are not for r134a at all. both ends are made for r12 hoses. they will not go on the bigger machine thread the r134a hoses have. I did not read the specifics in the title. these are 1/4 SAE thread but r134a is 1/2" machine thread. if you need R12 hoses, these are the ones to get. If you need r134a hoses, these won't work without buying adapters for both ends for each hose. seller offered a full refund and I accepted. I did not ask for a refund but seller offered, so I rank this seller 5 Star!

Kind of stiff but held a lot of pressure with no leaks.

Picked these up to seal a stripped schrader valve. It’s been a year and they’re still holding!

NOT recommended for closing off when pulling a vacuum and also have a pretty high failure rate. NO recommend at all to be honest. Out of 6 that I bought, 2 leak like a sieve, 1 other is a slow leaker, and none of them can hold against a vacuum (only on pressure). Just save yourself the pain. Unfortunately I didn't get a chance to use them before the return period expired so I'm stuck with paying for this junk.

Perfect exactly what I wanted

This product’s quality is disappointing. After only 3–4 uses, it began to leak, which indicates a need for improvement.

Item is as described and worked great

All is as promised. My thanks for the good product.

Bought this product for my HVAC company , the leads and valves leaking brand new outa the box .pretty useless when leaks are critical when vacuuming down a ac system.
