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!

Did not fit. Price for 6 pieces was too much.

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.

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.
