B K/mueller Inds(import) 520-201HC Black 45 Degree Elbow

Product Description

The B K/MUELLER INDS(IMPORT) 520-201HC is a 1/4 inch black 45 degree equal elbow designed for directional changes in low-pressure gas piping systems. This malleable fitting redirects flow at a 45 degree angle while maintaining consistent inside diameter through both ports. Sold in a package of 25 units, it is well suited for rough-in work or service calls that require multiple fittings. Licensed plumbers and gas fitters are the typical installers, though mechanical contractors also work with this fitting type in commercial applications.

This fitting is used in residential and light commercial gas piping installations where a 45 degree change of direction is required. The black iron finish distinguishes it from galvanized fittings and is the standard choice for natural gas and propane distribution lines. It is commonly installed during new construction rough-in, system modifications, or appliance connection work where threaded black pipe is already in use.

Key Features

• 45 degree angle provides mid-range directional change without a full 90 degree turn
• Equal end sizing at 1/4 inch on both ports for straight inline transitioning
• Black finish compatible with standard black iron gas pipe systems
• Package quantity of 25 units supports multi-fitting jobs and service truck stocking
• Threaded connection type for compatibility with standard NPT pipe fittings

Compatibility

Designed as an OEM-style replacement fitting for use with standard 1/4 inch threaded black iron pipe in residential and commercial gas piping systems.

Installation Notes

Installation should be performed by a licensed plumber or gas fitter in accordance with applicable local codes and IFGC requirements. Shut off the gas supply and verify zero pressure in the line before disassembling or installing any threaded fittings. Apply approved thread sealant or PTFE tape rated for gas service to all male threads before assembly. Never overtighten threaded fittings, as this can crack the fitting or damage pipe threads.
