B K Mueller 510-001HN Galvanized 90 Degree Elbow 1/4 in

Product Description

The B K Mueller Industries 510-001HN is a 1/4-inch galvanized steel 90-degree equal elbow designed for use in threaded pipe assemblies. This fitting redirects flow at a right angle while maintaining consistent inside diameter throughout both ports. The hot-dip or electro-galvanized coating provides corrosion resistance for installations in damp or moderately corrosive environments. Plumbers and pipefitters install this type of fitting in low-pressure gas, water, and air distribution lines where a 90-degree change of direction is required. The equal-port design means both ends share the same nominal pipe size, simplifying procurement and layout on the jobsite.

This elbow is suited for residential and light commercial plumbing and gas piping applications. It is commonly installed in threaded black-and-galvanized pipe systems for natural gas distribution, compressed air lines, and water supply roughin work. The 1/4-inch nominal size makes it a common choice for branch lines, instrument taps, and pilot supply connections in HVAC and plumbing systems. This SKU is packaged in quantities of 10 units per package, making it practical for service vans and supply-house restocking.

Key Features

• 90-degree turn in a single equal-port fitting — no reducing bushings required
• Galvanized finish provides corrosion resistance in damp or moderately harsh environments
• 1/4-inch nominal pipe size fits standard NPT threaded pipe systems
• Equal elbow design — both inlet and outlet are the same nominal diameter
• Sold in a 10-unit package for efficient restocking

Compatibility

Designed as an OEM-style replacement and standard-fit component for 1/4-inch NPT threaded galvanized or black-iron pipe systems in plumbing, gas, and compressed air applications.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters working on threaded pipe systems. Shut off and depressurize the supply line before removing or installing any threaded fitting. Apply thread sealant tape or pipe dope rated for the intended service — gas, water, or air — to the male threads before assembly. Follow applicable code requirements, including IPC for water systems and IFGC for gas piping, regarding fitting material and joint sealing methods.
