Bmi Usa 35315 Black 90 Degree Pipe Elbow 1/4 X 1/8

Product Description

The BMI USA 35315 is a malleable iron black 90-degree pipe elbow designed for threaded piping systems in residential and light commercial plumbing, gas distribution, and HVAC applications. This reducing elbow transitions from a 1/4-inch run to a 1/8-inch branch at a right angle, allowing direction changes in tight piping layouts. The black finish indicates a non-galvanized iron fitting, which is standard practice for natural gas and propane lines. Malleable iron construction provides the ductility needed to withstand mechanical stress and vibration without cracking, making it a reliable choice for code-compliant threaded systems.

This elbow is suited for low-pressure gas piping, compressed air lines, and general plumbing installations where a 90-degree directional change and a size reduction are required in the same fitting. The reducing configuration eliminates the need for a separate reducing coupling, saving space and connection points in confined rough-in areas. Licensed plumbers and HVAC technicians typically use this fitting when transitioning from a main run to a smaller branch or appliance connection.

Key Features

• Malleable iron construction resists mechanical stress and vibration in threaded piping systems
• Black (non-galvanized) finish suitable for natural gas and propane piping per code requirements
• 90-degree elbow with reducing configuration: 1/4-inch inlet to 1/8-inch outlet
• Threaded connections for standard NPT assembly without special tooling
• Compact, lightweight design at 0.1 pounds for use in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded piping systems requiring a 1/4-inch to 1/8-inch reducing 90-degree elbow.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) as applicable. Shut off all gas supply or system pressure and verify zero pressure before disassembling or joining threaded fittings. Apply approved thread sealant or PTFE tape rated for the intended service to all male threads before assembly. Do not over-tighten threaded joints; use a pipe wrench and back-up wrench technique to avoid stressing adjacent pipe or fittings.
