Composite thru-hull fitting 38mm 90deg

Table feed-through with 90 degree hose connection. Made of reinforced acetal plastic. The material is very strong and cannot corrode. The front ring made of stainless acid-free steel, which is highly polished, makes it look like a stainless feed-through from the outside. The hose is installed tilted upwards, creating a water trap. Can be used as an air vent for septic tanks. 19 mm is required to avoid squeezing the tank when the pump is emptying.
