Macomb Group Approved 1838-167 Cpvc Sch 80 Flush Bushing

Product Description

The MACOMB GROUP APPROVED 1838-167 is a solid-style flush bushing designed for Schedule 80 CPVC piping systems. Manufactured from Corzan CPVC and molded to meet ASTM D1784 Type IV Grade I Cell Class 23447 and ASTM F439 standards, this bushing transitions a 1-1/4 inch spigot connection to a 3/4 inch female NPT threaded connection. It carries an NSF/ANSI Standard 14 and 61 Annex G listing, making it suitable for potable water and industrial fluid handling applications. Licensed plumbers and pipe fitters install this fitting where Schedule 80 thermoplastic systems require a reduction with a threaded outlet. The gray finish and 1.66 inch length confirm its compact, flush profile.

This bushing fits inline reducer and adapter applications in Schedule 80 CPVC pressure piping systems. It is commonly used in commercial plumbing, industrial process lines, and chemical handling systems where corrosion resistance and elevated temperature performance are required. The spigot-by-female-NPT configuration allows the bushing to be solvent-cemented into a socket fitting on the 1-1/4 inch side while accepting a threaded male connection on the 3/4 inch outlet. Typical installation environments include mechanical rooms, process piping manifolds, and anywhere CPVC replaces metal piping for corrosive service.

Key Features

• Corzan CPVC material provides superior chemical and heat resistance versus standard PVC
• Schedule 80 wall thickness rated for higher pressure service than Schedule 40
• Temperature rating of 210 degrees F suits hot-water and industrial process lines
• Spigot x FNPT connection allows solvent-cement to socket on one end and threaded assembly on the other
• NSF/ANSI 14 and 61 Annex G listed for potable water contact
• Molded solid-style flush bushing construction for a compact, low-profile fit

Compatibility

Designed as an OEM-style replacement and standard-fit component for Schedule 80 CPVC pressure piping systems requiring a 1-1/4 inch spigot to 3/4 inch female NPT reducing bushing per ASTM F439.

Installation Notes

Installation must be performed by a licensed plumber following applicable local plumbing codes and IPC guidelines. De-pressurize and drain the piping system completely before cutting or assembling fittings. Use a CPVC-rated solvent cement and primer on the spigot end; do not use PVC-only cement on Corzan CPVC fittings. Allow full cure time per the cement manufacturer before restoring system pressure.
