1 1/2 in. Black Merch Coupling are machined from rolled steel. They join pieces of pipe together for a stronger extension.
The only fittings we sell made of the same industrial steel we make our pipe from. They are manufactured to the same spec as all our other fittings but with the added benefit of steel. Hydrostatically tested good for air, gas, decor, and liquid propane. Each coupling joins the same size pipe securely. Suitable for any situation you need to extend your pipe.
