Attwood pump fitting
Very thin plastic. Only reason im using it is because nothing else fits the thread of the attwood pump.
When tightened to the pump the rubber seal washer does not feel firm. I dont think the fitting will take another turn with out breaking. Im not confident of a good seal that wont leak.
Ive been working around plumbing and mobile hyraulics my whole life and this is bad engineering/design.
Attwood needs to step up their game and make their pumps with common fittings that can be bought at any hardware store.
