    Used it to fix my Big EZ dye injection gun. Didn’t have to buy a whole new gun.

    I had a hard time trying to connect it to my 2003 Mazda Protege ac connection. I had to use tremendous amount of force to eventually lock it onto the suction connection. Once connected, it sits solidly and did not leak. It was well built. I give 2 stars because of difficulty with connection.

    I’m glad Robinair considers the need to replace these connectors. I’ve had connectors that were crimped onto the hose, and the whole unit is wasted if the connector starts failing. Easy to use, but make no mistake, these can fail just like any other tool. High side more often than low side.

    It’s OEM. The last time I had to replace one was about 10 year ago.
