1 inch Lead-Free Brass Union – Flare x Flare, Designed for High-Integrity Connections

The 1 inch Flare x Flare Union is a precision-machined brass fitting used for joining two flared tubing ends in fluid or gas systems. Manufactured from lead-free brass in compliance with current potable water regulations, this union provides a mechanically strong, reusable connection that is suitable for service in residential, commercial, and light industrial applications.

This fitting features dual flare-end connections and is typically used where quick disassembly is required without cutting or soldering. The union’s flare design provides metal-to-metal sealing, minimizing the need for additional sealants and ensuring reliable, leak-resistant operation under pressure and vibration.
