4 in. PVC Schedule-40 DWV Male Adapter MIPT X Spigot Fitting for Drain, Waste, and Vent Pipe ASTM D2665 NSF

The 4 in. PVC Schedule-40 DWV Male Adapter MIPT x Spigot Fitting from 247Garden is a rugged and reliable solution designed for seamless transitions between solvent-weld DWV systems and threaded connections. Made from durable white PVC and manufactured in accordance with ASTM D2665 and NSF standards, this fitting is engineered for long-lasting performance in drain, waste, and vent (DWV) systems.

The spigot end fits securely into the hub of another 4" DWV HUB/SLIP fitting, while the MIPT (Male Iron Pipe Thread) end provides a strong, threaded connection point for any female-threaded components such as cleanout caps, female adapters, or other threaded PVC or metal parts. This makes it especially useful for cleanouts, equipment transitions, or any area where future disassembly may be required.

Whether you're working on new construction, repair, or retrofitting an existing plumbing system, this adapter is built to maintain system integrity and ease of maintenance. It resists corrosion, chemical degradation, and microbial growth—ensuring a long service life in both above- and below-ground installations (as permitted by local code).
