The VALUE COLLECTION 839-166 is a Schedule 80 PVC pipe bushing designed to reduce a 1-1/4 inch female pipe thread to a 1/2 inch male pipe thread within pressurized water, irrigation, and chemical distribution systems. Constructed from rigid PVC, this bushing handles moderate pressure service and offers strong resistance to corrosion, scale buildup, and a wide range of chemicals. The MIPT x FIPT end configuration allows direct threaded installation into existing pipe fittings without specialty tools. Licensed plumbers and pipefitters install this type of fitting during new construction, system modification, or repair work where a reduction in pipe size is required at a threaded joint.
This bushing is suited for residential and light commercial plumbing systems, irrigation lines, pool and spa piping, and industrial process lines that require a PVC-compatible threaded reduction. Schedule 80 wall thickness makes it appropriate for higher-pressure applications compared to Schedule 40 equivalents. It is commonly installed in above-ground and below-grade threaded piping runs where corrosion resistance and dimensional stability are priorities.
Designed as an OEM-style replacement or new-installation threaded bushing for Schedule 80 PVC piping systems using standard NPT threaded connections.
Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and ASTM standards for PVC threaded fittings. Depressurize and drain the system completely before removing or installing any threaded fitting. Apply PTFE thread tape or an approved pipe thread sealant to the male threads before assembly. Do not overtighten PVC threaded fittings — hand-tight plus one to two turns with a strap wrench is typical; use of pipe wrenches directly on PVC can crack the fitting body.
