Description
A 3/4″ Coupler (also called a Full Coupling) is a straightforward but essential fitting used to join two lengths of pipe or two male-threaded fittings together. It consists of a hollow cylinder with Female Pipe Threads (FPT) running through the entire length.
Key Features
-
Internal Threading: Features 3/4″ Female Pipe Threads (FPT) on both ends. It acts as the “bridge” that allows you to connect two male components, such as two pipe nipples or a hose barb and a male pump outlet.
-
304 Stainless Steel: This high-grade alloy provides excellent resistance to corrosion, rust, and chemical damage. In industries like soft washing or chemical processing, it is the standard for handling bleach (sodium hypochlorite), soaps, and water.
-
Class 150 (150#) Construction: Cast to industrial standards, providing the durability needed for the vibration and moderate pressure found in commercial pump systems.
-
Compact Strength: Unlike “straight” pipe segments, the coupler is reinforced to handle the mechanical stress of joining two separate components under tension.
