Bronze 90-Degree Elbow for Potable Water

This 1 1/4-inch bronze elbow connects copper tubing to female NPT threads in potable-water systems. The C87850 alloy meets NSF/ANSI 61 and 372 for safe drinking-water contact. Rated for 351 psi at 200 degrees F, it suits residential and light-commercial supply lines. Sweat and threaded ends allow a permanent joint without additional adapters.

Standards-Driven Material and Certification

The fitting conforms to ASME B 16.18 dimensional requirements and is produced under ISO 9001 quality management. NSF/ANSI 61 and 372 certifications confirm lead-free compliance for potable-water installations. These markings let inspectors verify code acceptance on sight. No extra components or sealants are bundled with the single-piece casting.

Pressure and Temperature Headroom

The 351 psi rating provides margin above typical municipal pressures well below that figure. The 200-degree F limit covers standard hot-water distribution temperatures. Systems exceeding either value will require a higher-rated fitting or a different material. The 90-degree bend fixes the flow direction; layouts needing other angles must source additional fittings.

Questions about this item

Will the bronze body or the sweat cup joint need replacement if the system runs near the 351 psi pressure limit?

The C87850 bronze elbow is rated for 351 psi at 200 °F; the sweat cup and FNPT threads are permanent joints, so no scheduled replacement is required unless corrosion or mechanical damage occurs.

What is the first limit reached when hot water circulates continuously through this 90-degree elbow?

The maximum operating temperature of 200 °F is the primary thermal limit; sustained exposure above that temperature would exceed the fitting's rating before pressure becomes a concern.

Does the bronze fitting generate noise or add heat loss when installed in a recirculating potable-water loop?

The fitting itself has no moving parts and produces no noise; its bronze mass adds negligible heat loss compared with the copper tubing it connects.
