B K/mueller Inds(import) 520-208HN Black 45 Degree Elbow

Product Description

The B K/MUELLER INDS(IMPORT) 520-208HN is a 2-inch black 45-degree equal elbow designed for use in threaded pipe systems. This fitting redirects flow at a 45-degree angle and is manufactured with a black finish suited for gas distribution and related piping applications. Sold in a package of 3 units, it is a standard trade fitting installed by licensed plumbers and pipefitters working on residential and light commercial systems. The equal-end configuration means both inlet and outlet share the same 2-inch nominal pipe size, simplifying ordering and installation planning.

This elbow is used in threaded black iron piping systems, most commonly in natural gas and propane distribution lines within residential and commercial buildings. The 45-degree angle makes it well suited for routing pipe around obstructions or making gradual directional changes where a 90-degree elbow would create excessive flow restriction or spatial conflict. Plumbers and gas fitters rely on fittings of this type during rough-in and retrofit work on fuel gas piping systems governed by the International Fuel Gas Code.

Key Features

• 45-degree angle for gradual directional changes in threaded pipe runs
• Equal end sizing at 2 inches nominal on both inlet and outlet
• Black finish suitable for gas piping applications
• Sold in a package of 3 units for convenient stocking
• Threaded connection type compatible with standard NPT pipe fittings

Compatibility

Designed as an OEM-style replacement fitting for standard 2-inch NPT threaded black iron pipe systems used in gas and related piping installations.

Installation Notes

Installation should be performed by a licensed plumber or gas fitter in accordance with the International Fuel Gas Code and applicable local codes. Shut off and verify the absence of gas pressure in the line before disconnecting or installing any fitting. Apply an approved pipe thread sealant or PTFE tape rated for gas service to all male threads before assembly. Do not overtighten threaded connections, as this can crack cast fittings or damage threads.
