This is a hose I had on my equipment last year. Brass fitting, suction hose out of my tank to a 3 way banjo valve. I always rinsed the valve pump and hose reel and never thought about the suction line not getting rinsed. Got lucky and finished my last job last year when i noticed it was leaking. I will be using poly or stainless from now on. It actually lasted 2 years.
