The CHARLOTTE PIPE FOUNDRY CO. PVC 02101 3800HA is a white PVC reducing female adapter designed for slip-to-thread transitions in irrigation and sprinkler piping systems. It connects a 1-inch slip socket inlet to a 3/4-inch female threaded outlet, with internal pipe threads that accept male-threaded fittings. Built from schedule-rated PVC, this adapter meets ASTM D 2466 requirements and is sold in packages of 25 units. Plumbers, irrigation contractors, and sprinkler system installers use this fitting to reduce line size while transitioning from solvent-welded pipe to threaded connections.
This adapter is commonly used in residential and light commercial sprinkler and irrigation systems where a mainline or lateral must step down from 1-inch PVC pipe to a 3/4-inch threaded connection point. Typical install scenarios include zone valve connections, riser assemblies, and lateral feed lines where a slip-to-thread reduction is required. The internal threading accepts standard male NPT fittings used throughout irrigation manifolds and sprinkler heads.
Designed as an OEM-style replacement and standard fitting for 1-inch PVC slip-to-3/4-inch female threaded connections in residential and commercial sprinkler and irrigation systems.
Installation is typically performed by licensed plumbers or certified irrigation contractors. Shut off system water supply and relieve line pressure before cutting into existing pipe. The slip socket end requires solvent cement compatible with PVC Schedule 40; follow ASTM D 2564 procedures for proper joint assembly. Apply thread sealant tape or compound to male threads before engaging the female adapter to ensure a leak-free connection.
