Ipex 36634 Pvc Sch 80 Spigot X Socket Bushing 6x4 in

Product Description

The IPEX 36634 is a PVC Schedule 80 spigot-by-socket reducing bushing designed for industrial and commercial piping systems. It transitions a 6-inch spigot connection down to a 4-inch socket, allowing installers to reduce line size within a pressure-rated PVC piping system. Schedule 80 wall thickness provides added pressure capacity compared to Schedule 40, making it suitable for demanding process piping applications. The fitting is manufactured to strict dimensional and performance standards and carries NSF and CSA International listing for use with potable water. Plumbers and pipefitters working in chemical process, industrial, and municipal water systems are the primary installers.

The IPEX 36634 is suited for industrial process piping, chemical handling systems, commercial plumbing, and potable water distribution where a 6-inch to 4-inch reduction is required. Its PVC construction makes it appropriate for service with a broad range of acids, alcohols, alkalis, salt solutions, and halogens. The Schedule 80 rating supports higher operating pressures than standard-weight fittings, making it a common choice in process lines where pressure margins matter.

Key Features

• PVC Schedule 80 construction provides higher pressure ratings than Schedule 40
• Smooth interior bore resists rust, pitting, scaling, and corrosion throughout service life
• Outstanding chemical resistance to most acids, alcohols, alkalis, salt solutions, and halogens
• NSF and CSA International listed for use with potable water
• Spigot-by-socket end configuration allows direct integration into standard PVC socket-weld systems
• Lower embodied energy compared to same-size steel or steel-alloy fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for PVC Schedule 80 piping systems requiring a 6-inch spigot to 4-inch socket reducing connection.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with solvent-cement joining of PVC pressure fittings per ASTM D2564 procedures. Depressurize and drain the line completely before cutting or joining. Use only PVC-rated solvent cement and primer appropriate for Schedule 80 fittings; do not substitute CPVC or ABS cements. Follow applicable plumbing code requirements, including IPC and local amendments, for support spacing and pressure testing after installation.
