The Coupling simply connects two piece of tubing. These are perfect if a mistake was made when cutting your tubing or if you want to remove a spray nozzle from an area. Essentially, the Coupling is a way to splice two pieces of tubing together.
All of our fittings are nickel plated, which provide years of non-tarnishing luster. These are quick fit designed whereas the tubing simply pushes into the fitting until the internal "teeth" grab it and lock it into place. To release the tubing, simply push in the collar surrounding the tubing to release the "teeth" and pull the tubing out.
Inline Check Valves allow flow in one direction and automatically prevents back flow or reverse flow when fluid in the tubing reverses direction.
These are primarily used in system designs where there is a large number of spray nozzles and large lengths of tubing. They are connected to your tubing to ensure that spray nozzles furthest from the pump receive adequate pressure at the same time as those spray nozzles closest to the pump, when the system activates.
