gohantee70'' R410A AC Charging Hose Set for HVAC Air Condition Refrigerant R134A R12 R22

They hold up to the pressure. The schreder valve on the hoses have to be opened up when you get them. Make sure you give them a few turns counter clock wise so it opens the schreder valve up all the way. Other then that I'm happy with them.

Exact product. Good quality. Fast delivery

Got these to replace my very old and now stiff Yellow Jacket hoses. Seem to be good quality, flexible and include rubber seals at the connectors. Just use caution for the first time I used the hoses and unscrewed one hose from my refill Freon can, the rubber gasket fell out of the hose connector and into the engine bay. Way to small and it blends in too well to find where it went. Have to get a replacement hose gasket now and those only come in sets of 10 or more rubber gaskets which is almost as much as just buying a new single hose all over again. Just be careful when everything is new and you unscrew the hoses.

Hello Amazon, thank you.It’s great. Would recommend to others.

Hose’s are made of good quality materials and work as they supposed too. Another thing is that they seal very good since the have green rubber insert gaskets, in stead of the white hard plastic type you get when you buy a a/c manifold for 134 type refrigerant, plus they are replaceable if they ever go bad.
