Its the right product, from the original manufacturer. Took some time installing them. A Q-tip with vaseline applied on the gasket, and in the fitting kept the gasket from getting damaged. Its a TIGHT fit!

perfect replacment for my auto AC set. those pesky seals always pop out of my setup and these are handy to keep in an old film canister.

Did not fit. Price for 6 pieces was too much.
Maurice Price –
Works as intended
Wonk –
They are most certainly worth the purchase.

Could not find these at one hvac distributor in all of town. Correct size for your standard vaccum hose on a 4 port manifold. The other three hoses are 1/4inch.
Nikkita Matata –
It worked for what I needed. I am very happy with it.

Feels more like rubber or rubber-silicone blend than just soft silicone like most foreign made junk. Pricey, but Robinair is a well known a/c products company that will stand by their products.Only drawback is that these are a very tight fit, but that’s better than a loose fit that will pop out of the fitting on disconnect.Use an a/c lube or vaseline or any appropriate oil to help with installation.
