B K/mueller Inds(import) 511-964HN Galvanized Hex Bushing

Product Description

The B K/MUELLER INDS(IMPORT) 511-964HN is a galvanized hex bushing used to reduce a larger female-threaded pipe connection to a smaller male-threaded pipe connection. Measuring 1-1/4 inches by 3/4 inches, this fitting bridges two pipe sizes in a threaded piping system. The hex body allows standard wrench engagement for a secure, leak-free installation. The galvanized finish provides corrosion resistance in wet or humid environments, making it suitable for water supply, gas distribution, and general plumbing rough-in applications. Plumbers and pipefitters install this fitting where pipe size reductions are required in threaded systems.

This hex bushing is used in residential and light commercial plumbing and gas piping systems wherever a 1-1/4 inch threaded pipe or fitting must transition down to a 3/4 inch male thread. Common install scenarios include reducing branch lines at manifolds, tees, and valves, or adapting larger-diameter pipe runs to smaller downstream connections. The galvanized construction suits both interior and exterior installations where moisture exposure is a concern.

Key Features

• 1-1/4 inch female thread to 3/4 inch male thread reduction in a single fitting
• Hex body design accepts standard pipe wrenches or adjustable wrenches for proper torque
• Galvanized finish resists corrosion in wet and humid service environments
• Sold in a package quantity of 5 units per package

Compatibility

Designed as an OEM-style replacement and general-use fitting for threaded pipe systems requiring a 1-1/4 inch to 3/4 inch bushing reduction.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters in accordance with applicable local plumbing codes and IFGC requirements where gas service is involved. Always shut off water or gas supply and relieve system pressure before removing or installing threaded fittings. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-tighten; use a wrench on the hex body to achieve a proper seal without stressing the fitting.
