Bk 510-300HC 1/8 in 90 Degree Street Galvanized Elbow

Product Description

The BK 510-300HC is a 1/8-inch 90-degree street galvanized malleable iron elbow, also known as a quarter bend, used in threaded pipe assemblies where a direction change is required in a tight space. This fitting features a male thread on one end and a female thread on the other, allowing it to thread directly into a fitting without a nipple in between. Constructed from galvanized malleable iron meeting ANSI/ASTM A-197 material standards, it delivers corrosion resistance and durability in low-pressure plumbing and gas applications. Each fitting is individually flag tagged and 100 percent inspected and quality tested before leaving the facility.

This street elbow is suited for residential and light commercial plumbing, gas distribution, and mechanical piping systems where 1/8-inch NPT threaded connections are required. It is commonly installed in tight-clearance situations where a standard elbow and separate nipple would not fit. The Mueller logo is cast into the body of each fitting, confirming manufacturing traceability. Plumbers and pipefitters working on small-diameter threaded systems will find this fitting compatible with standard NPT pipe and fittings.

Key Features

• Galvanized malleable iron construction per ANSI/ASTM A-197 for corrosion resistance
• 90-degree street configuration with male and female NPT ends for direct fitting-to-fitting installation
• Dimensions conform to ANSI/ASME B16.3, B16.14, and B16.39 standards
• Threads cut to ANSI B1.20.1 NPT specification for reliable sealing
• Individually flag tagged and 100 percent inspected at the factory
• Mueller logo cast into body for product identification and traceability

Compatibility

Designed as an OEM-style replacement and standard fitting for 1/8-inch NPT threaded pipe systems in residential and commercial plumbing and mechanical applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters working on threaded pipe systems. Shut off the water or gas supply and relieve system pressure before disassembling any existing fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, following local plumbing code requirements. Do not over-tighten; use a pipe wrench with controlled force to achieve a leak-free joint without cracking the fitting.
