3/4 in. SCH-40 PVC Male NPT x Female NPT Adapter/Threaded Coupling Pipe Fitting NSF ASTM D2466 MIPT x FIPT

The 247Garden 3/4-inch Schedule 40 PVC Male NPT x Female NPT Adapter, also known as a PVC Riser Extension, is a reliable and versatile threaded coupling designed for connecting two pipes with NPT (National Pipe Thread) ends—one male and one female. Engineered for strength, chemical resistance, and durability, this fitting provides a secure and leak-resistant connection in both residential and commercial plumbing or irrigation systems.

Constructed from high-quality Schedule 40 PVC (Polyvinyl Chloride), this fitting meets ASTM D2466 and NSF standards for performance and safety. It’s corrosion-resistant, rust-proof, and capable of withstanding high-pressure water flow, making it ideal for both indoor and outdoor applications. The MIPT x FIPT (Male Iron Pipe Thread x Female Iron Pipe Thread) design allows for a simple threaded connection without the need for gluing—perfect for situations where disassembly or reconfiguration may be required.

Often referred to as a PVC riser or riser extension fitting, this adapter is widely used in irrigation systems to extend sprinkler risers, connect water lines, or transition between different threaded fittings. Its precision-molded threads ensure a tight, watertight seal when used with standard Teflon tape or thread sealant.
