Tyco Products 77213ES Rigid Coupling E Gasket 1-1/4

Product Description

The TYCO PRODUCTS 77213ES is a 1-1/4 inch rigid coupling supplied with an E gasket, designed for use in grooved-pipe fire protection and mechanical piping systems. Rigid couplings lock the pipe segments in place, preventing angular deflection or linear movement at the joint. This makes them the preferred choice when system design calls for a fixed, immovable connection rather than a flexible joint. The coupling is sold as a single unit and includes the E gasket required to complete the assembly. Installation is typically performed by licensed fire protection contractors or journeyman plumbers working on grooved mechanical systems.

This rigid coupling is suited for 1-1/4 inch nominal pipe diameter installations in sprinkler systems, fire suppression piping, and general mechanical piping where grooved-end pipe joining is specified. The E gasket included with the coupling is intended for standard service conditions typical of these applications. Always verify that the gasket material and coupling style match the pipe material, fluid type, and operating pressure requirements called out in the project specifications before installation.

Key Features

• Rigid coupling design locks pipe segments to prevent deflection or movement at the joint
• Nominal pipe size: 1-1/4 inches
• Includes E gasket for a complete, ready-to-install assembly
• Single-unit selling configuration
• Designed for use in grooved-pipe mechanical and fire protection systems

Compatibility

Designed as an OEM-style replacement or new-installation rigid coupling for grooved-pipe systems using 1-1/4 inch nominal pipe diameter.

Installation Notes

Installation should be performed by a licensed fire protection contractor or qualified pipefitter in accordance with NFPA 13 or the applicable mechanical code. Power down or isolate the affected section of pipe and depressurize the line before disassembling any existing joint. Ensure pipe ends are clean, free of burrs, and properly grooved to the coupling manufacturer's groove specification before seating the gasket and housing. Do not over-torque bolts beyond the coupling manufacturer's published fastener specification.
