The PRO-SOURCE 90380900209 is a Schedule 80 PVC female adapter fitting designed for joining threaded pipe systems to plain-end pipe runs. Sized at 1 inch, this fitting features a slip socket on one end and a female iron pipe thread (FIPT) connection on the other, allowing a smooth-bore pipe to transition into a threaded fitting assembly. Made from PVC, it suits low-pressure water distribution, irrigation, chemical handling, and other fluid-conveyance systems where metal corrosion is a concern. Plumbers and pipefitters install this adapter wherever a threaded entry point is required on a solvent-welded PVC line.
This adapter is suited for residential and light commercial plumbing, irrigation manifolds, pool and spa plumbing, and industrial process piping that operates within PVC pressure and temperature ratings. The Schedule 80 wall thickness provides greater pressure capacity and impact resistance compared to Schedule 40 fittings of the same nominal size, making it appropriate for applications that see elevated working pressures or mechanical stress at connection points.
Designed as an OEM-style replacement or standard-service fitting for 1 inch Schedule 80 PVC piping systems using solvent-weld and female threaded connections.
Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and local plumbing codes. Shut off and depressurize the system fully before cutting into any existing line. Clean and dry both mating surfaces before applying solvent-weld cement to the slip end; allow full cure time per the cement manufacturer before returning the line to service. Apply thread sealant tape or compound to the male threaded pipe end before engaging the FIPT connection, and do not overtighten, as PVC threads can crack under excessive torque.
