It provides a 2" MPT x FPT threaded connection for easy, corrosion-resistant extension of existing risers and fittings. Material: White Schedule 40 PVC for durability and chemical resistance. Thread type: 2" MPT x FPT (male pipe thread x female pipe thread), compatible with standard threaded PVC fittings. Standards: Manufactured to common PVC fitting standards including ASTM D2466 and ASTM D1784; listed to NSF/ANSI 61 and NSF 14 where applicable. Dimensions: Nominal 2" size; overall length approximately 2 11/16" for part 434-020 (varies by manufacturer). Applications: Ideal for irrigation, pool & spa, and other cold-water pressure distribution systems; not for compressed air or hot water applications. Installation is simple — thread the extender into a matching threaded riser or fitting using PTFE thread sealant or tape. Avoid using with compressed gases and consult local plumbing codes. If you need a solvent-weld connection, use the appropriate adapter or consult product specifications before installation.
