1 inch Bronze 90 Degree Radiator Elbow Hot Water Female x Male

1 inch Bronze 90° Radiator Elbow – FNPT x MNPT, Lead-Free, High-Pressure Rated

The 1 inch Bronze 90-Degree Radiator Elbow is specifically engineered for directional changes in hydronic heating systems. This elbow features a female NPT inlet and male NPT outlet, making it suitable for threaded transitions in confined or offset piping configurations. Manufactured from lead-free bronze, it meets NSF/ANSI 61 and 372 compliance for use in potable and closed-loop systems.

Performance and Material Benefits

• Pressure and Temperature Ratings: Designed for applications up to 400 PSI non-shock at ambient temperatures, suitable for hot water distribution and radiator tie-ins.
• Lead-Free Bronze Alloy: Resistant to dezincification, scaling, and internal corrosion. Compatible with copper, brass, and black steel threaded systems.
• Precision Machining: NPT threads are machined to ASME B1.20.1 tolerances, ensuring a tight mechanical seal with proper thread engagement.

Use Case Applications

Commonly used in heating system installations, this 90° elbow is ideal for:

• Baseboard radiator connections in residential boiler systems
• High-temperature loops in closed hydronic systems
• Threaded terminal unit fittings or manifold terminations
• Transitions from copper tube or iron pipe to devices with limited clearance

Installation Notes

Apply PTFE tape or anaerobic pipe thread sealant to male threads. Use two wrenches—one to stabilize the fitting body, the other to tighten—avoiding stress on nearby joints. Ensure alignment before torque to prevent galling or cross-threading.
