8 What are hose couplers?

A hose coupling is a piece of equipment used to connect a hose with something else, like a tap, sprinkler, pump or another hose.

This mounting style coupler locks on by sliding into the round shank tongue and welds on it.

This is a style for the straight tongue and it’s the most basic one.

It's used for A-shaped tongues and it’s made to withstand heavy duty towing.
