Aqualine GHXB-4030 Threaded Galvanized Bushing 4x3

Product Description

The AQUALINE GHXB-4030 is a threaded galvanized steel bushing designed to reduce a 4-inch pipe connection down to a 3-inch pipe connection. Bushings of this type seat inside a female-threaded fitting and provide a male-threaded outlet at the reduced size, allowing a single transition point without additional couplings or adapters. The galvanized finish provides corrosion resistance in wet and exposed environments. At 3.35 pounds, this is a heavy-duty fitting suited for commercial and residential piping systems where a durable, code-compliant threaded reduction is required. Licensed plumbers and pipefitters are the primary installers.

This bushing is commonly used in water supply, drain, and general piping applications where a 4-inch line must transition to a 3-inch line at a threaded joint. It is appropriate for residential and light commercial plumbing installations, irrigation systems, and pool or spa plumbing where galvanized threaded fittings are specified. The hex head design allows standard pipe wrenches or strap wrenches to be used for installation without damaging the fitting body.

Key Features

• Reduces 4-inch female thread to 3-inch male thread in a single fitting
• Galvanized steel construction for corrosion resistance in wet environments
• Heavy-duty build at 3.35 pounds for reliable, long-term service
• Hex shoulder design accommodates standard pipe wrenches for proper torque
• Threaded connection type for secure, leak-resistant joints with pipe compound or PTFE tape

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 4-inch to 3-inch threaded galvanized pipe systems in residential and commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before beginning work. Apply PTFE tape or approved pipe thread sealant to the male threads before assembly to ensure a leak-free joint. Do not over-tighten threaded fittings; use a pipe wrench on the hex shoulder only and avoid excessive force that could crack fittings or damage pipe threads.
