1-1/2 inch Chrome Spud Coupling Assembly with Nut and Flange

1-1/2" Chrome-Plated Brass Spud Coupling Assembly with Nut and Flange – Engineered for Secure Fixture Connections

The 1-1/2" Chrome Spud Coupling Assembly is a precision-engineered fitting used to connect fixtures such as flushometers to toilet bowls or urinals. Constructed from chrome-plated brass, it offers corrosion resistance, high mechanical strength, and a tight sealing interface for vertical and angled installations.

This assembly includes the coupling body, locknut, and flange, delivering a complete solution for commercial and institutional fixture installations that require long-term durability and compliance with plumbing code specifications. Its design supports consistent sealing performance even in high-traffic environments.

Key Performance Features

• ✅ Precision-Machined Threads: Enables secure, leak-resistant engagement with flush valves and fixture inlets.
• ✅ Chrome-Plated Brass Body: Provides superior resistance to corrosion and wear, maintaining appearance and function over time.
• ✅ Pressure-Rated Design: Withstands static and dynamic loads associated with commercial water delivery systems.
• ✅ Inclusive Kit: Includes spud coupling, locknut, and flange for a complete installation.
• ✅ Interchangeable Configuration: Compatible with standard flushometer and fixture configurations, supporting both retrofit and new installations.

Installation Guidelines

This coupling is typically installed between a flushometer tailpiece and a vitreous china inlet horn. A smooth mating surface is essential to ensure a watertight connection. Use of approved thread sealants and torque-controlled tightening of the locknut are recommended for optimal fit and function. Ensure alignment with fixture inlet to prevent mechanical stress or improper seating of seals.
