Hardware is extremely cheap. Came with a broken compression fitting. Not sure if they offer any replacement parts but this fitting is not coming out. Effectively I need a new control valve block.Update: so I went to my local hardware store and purchased some barbed fittings. I also bought some reinforced 250psi hose. Seems to be working well now. Personally I trust my fix more than the original compression fittings. As always use jack stands if you are using any type of jack. Oh…I also used Gorilla glue tape over the clamp on the bag end just to keep the bag from directly contacting the clamp.
