Tigre Usa Inc 36-6551 Pvc Adapter Bushing 4x1.5 Inch

Product Description

The TIGRE USA INC 36-6551 is a PVC adapter bushing designed to reduce a 4-inch spigot connection down to a 1.5-inch hub connection. This fitting is used in drain, waste, and vent (DWV) piping systems where a larger-diameter pipe or fitting must transition to a smaller-diameter line. Constructed from white PVC, it provides a secure, solvent-weld connection at both ends. Licensed plumbers and pipefitters typically install this type of reducer bushing during new construction or remodel work when branch lines or fixture connections require a size step-down within a PVC system.

This bushing is suited for residential and light commercial plumbing applications. It fits into standard 4-inch PVC hubs and accepts a 1.5-inch PVC spigot, making it a common solution for connecting smaller fixture drain lines or cleanout fittings to a 4-inch main. The white PVC construction is typical for above-slab and in-wall DWV installations where the fitting is not exposed to direct UV or heavy mechanical stress.

Key Features

• 4-inch spigot end transitions to 1.5-inch hub for size reduction in PVC DWV lines
• White PVC construction for use in standard drain, waste, and vent systems
• Solvent-weld connection on both ends for a permanent, leak-resistant joint
• Sold in a package quantity of 25 units per carton

Compatibility

Designed as an OEM-style replacement and new-installation fitting for standard PVC DWV piping systems using 4-inch spigot and 1.5-inch hub connections.

Installation Notes

Installation is performed by a licensed plumber following local plumbing codes and IPC guidelines. Shut off water supply and ensure the pipe is dry before applying primer and solvent cement. Use only PVC-rated primer and cement rated for DWV applications, and allow full cure time before restoring flow. Do not use this fitting in pressurized supply lines.
