Bushing, MPT x FPT (Flush Style) PVC Schedule 80 1-1/2" x 1" (839-211)

This 1-1/2" x 1" Schedule 80 PVC Flush Bushing provides a compact, inline solution for reducing a 1-1/2" female-threaded port down to a 1" male-threaded connection in pressure piping systems. Constructed in dark gray Schedule 80 PVC, it delivers the elevated wall thickness and impact resistance required in industrial, chemical, and commercial plumbing installations where standard Schedule 40 fittings are insufficient.

The flush style design eliminates the protruding hex shoulder found on standard hex bushings, creating a low-profile, streamlined transition that installs cleanly inside existing female-threaded fittings without adding unnecessary bulk to the assembly. Both the 1-1/2" MPT exterior and the 1" FPT interior are cut to NPT tapered thread standards for a reliable, pressure-tight mechanical seal when made up with thread sealant or PTFE tape.

Rated to 630 psi at 73°F (governed by the 1-1/2" MPT end), this bushing is well-suited for demanding pressure service across a wide range of fluid handling applications. Its PVC composition provides excellent resistance to acids, bases, salts, and chlorinated water, making it a durable long-term choice in corrosive environments where metal fittings would degrade. NSF/ANSI 61 listing confirms suitability for potable water contact.

Install using a quality pipe thread sealant or PTFE tape on all threaded joints. Avoid over-torquing — PVC threads require hand-tight plus one to two turns; excessive force can crack the fitting. Derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Industrial Process Piping — Reduces line size at pump inlets, valve ports, equipment connections, and instrumentation taps in chemical processing, water treatment, and manufacturing facilities
• Commercial Plumbing — Adapts 1-1/2" threaded ports on fixtures, manifolds, and valve assemblies to 1" branch lines in pressurized water supply systems
• Irrigation & Water Distribution — Provides a compact, corrosion-resistant thread reducer in agricultural and municipal irrigation headers
• Chemical Handling — Performs reliably in systems conveying acids, caustics, fertilizer solutions, and other corrosive fluids incompatible with metal fittings
• Aquaculture & Water Features — Used at filter housings, pump connections, and header transitions where a low-profile bushing preserves tight spatial clearances
• HVAC & Mechanical Systems — Reduces threaded connections on cooling towers, chilled water loops, and treated water systems requiring Schedule 80 pressure rating
