Bk 510-301BG 1/4 in 90 Deg Street Galvanized Elbow

Product Description

The BK 510-301BG is a 1/4-inch 90-degree street galvanized malleable iron elbow, also known as a 1/4 bend, used to change pipe direction in low-pressure fluid and gas piping systems. Constructed from galvanized malleable iron to ANSI/ASTM A-197 standards, this fitting provides corrosion resistance and the flexibility to handle mechanical stress without cracking. It ships individually flag tagged and carries the Mueller logo cast directly into the body. Licensed plumbers and pipefitters install this fitting in residential and light commercial applications where a male-to-female street configuration simplifies directional changes without requiring an additional nipple.

This street elbow is suited for use in water supply, drainage, and low-pressure gas piping systems where galvanized iron fittings are specified. The street configuration features one male-threaded end and one female-threaded end, allowing it to thread directly into another fitting. It is commonly installed in tight spaces where standard elbow and nipple combinations would not fit. Plumbers and pipefitters working on retrofit or new-construction projects choose this fitting when galvanized iron piping is required by specification or local code.

Key Features

• Galvanized malleable iron construction per ANSI/ASTM A-197 for corrosion resistance and ductility
• Dimensions conform to ANSI/ASME B16.3, B16.14, and B16.39 standards
• Threads machined to ANSI B1.20.1 for consistent, leak-free engagement
• Street configuration with one male and one female threaded end
• Mueller logo cast into body; individually flag tagged for quality traceability
• 100 percent inspected and quality tested prior to shipment

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4-inch galvanized malleable iron pipe systems conforming to ANSI/ASME dimensional standards.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off the water or gas supply and relieve system pressure completely before threading any fitting. Apply an appropriate pipe thread sealant or PTFE tape to the male threads in accordance with local plumbing codes before making up the joint. Do not over-tighten; use a properly sized pipe wrench and follow applicable IPC or IFGC guidelines for fitting assembly.
