The VALUE COLLECTION 839-129 is a Schedule 80 PVC reducer bushing used to transition between pipe sizes in threaded piping systems. It connects a 1-inch male iron pipe thread (MIPT) on the outer end to a 3/8-inch female iron pipe thread (FIPT) on the inner end, reducing flow path diameter within the fitting itself. Schedule 80 PVC wall thickness provides greater pressure ratings and mechanical strength compared to Schedule 40, making this bushing suitable for moderate-pressure service in chemical, industrial, and plumbing applications. It weighs 0.05 pounds. Plumbers and pipefitters install this fitting when downsizing a branch line or capping a larger threaded port to a smaller connection.
This reducer bushing is used in threaded PVC piping systems found in residential and commercial plumbing, irrigation, chemical handling, and industrial process lines. It is installed wherever a threaded 1-inch port must be reduced to accept 3/8-inch threaded pipe or tubing. The MIPT x FIPT configuration allows it to thread directly into a female-threaded fitting, valve, or tee while accepting a male-threaded 3/8-inch pipe on the opposite end.
Designed as an OEM-style replacement or standard fitting for Schedule 80 threaded PVC piping systems requiring a 1-inch to 3/8-inch pipe size reduction.
Installation is performed by licensed plumbers or qualified pipefitters working with threaded PVC systems. Shut off and depressurize the line before removing any existing fittings. Use PTFE thread tape or an approved thread sealant on male threads before assembly, and hand-tighten followed by wrench tightening — do not overtighten PVC threads, as this can crack the fitting. Follow applicable IPC or local plumbing code requirements for pressure rating and listed fittings in the specific service environment.
