Bk 510-307BG 1-1/2 in 90 Deg Street Galvanized Elbow

Product Description

The BK 510-307BG is a 1-1/2 inch 90-degree street galvanized malleable iron elbow, also referred to as a 1/4 bend. Designed for threaded pipe assemblies, this fitting connects a male-threaded pipe end directly to a female-threaded run, eliminating the need for an additional nipple and reducing overall joint count. The body is galvanized malleable iron conforming to ANSI/ASTM A-197, providing corrosion resistance suited to plumbing, gas distribution support piping, and general industrial pipe work. Each fitting carries the Mueller logo cast directly into the body and is individually flag tagged for traceability.

This elbow is appropriate for residential and light commercial applications where 1-1/2 inch threaded galvanized pipe systems require a 90-degree directional change at a street fitting. Typical install scenarios include water supply rough-in, gas line support piping, and general mechanical piping where malleable iron threaded fittings are specified. The street configuration is commonly used in tight spaces where a male-to-female turn is needed without an additional coupling or nipple.

Key Features

• Galvanized malleable iron body meets ANSI/ASTM A-197 material standard
• Dimensions conform to ANSI/ASME B16.3, B16.14, and B16.39
• Threads cut to ANSI B1.20.1 NPT specification for leak-free makeup
• Street configuration with one male and one female threaded end
• 100 percent inspected and quality tested at the factory
• Mueller logo cast into body; individually flag tagged for job-site identification

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch NPT threaded galvanized malleable iron pipe systems where a 90-degree street elbow is required.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters working with threaded galvanized pipe systems. Shut off the water or gas supply and depressurize the line before breaking any existing joint. Apply an approved thread sealant or PTFE tape to all male threads before makeup, and tighten to a firm, wrench-tight connection without over-torquing the malleable iron body. Work must comply with applicable local plumbing codes and reference standards such as the IPC or IFGC as appropriate to the system.
