Spears 4235-010 Cpvc Flameguard Female Adapter 1 in

Product Description

The SPEARS 4235-010 is a 1-inch CPVC FlameGuard female adapter with a brass thread insert, configured in a Socket x FIPT end connection style. This fitting transitions from a solvent-weld socket connection to a female iron pipe thread using a factory-installed brass insert, which reinforces the threaded port and reduces the risk of thread deformation under repeated service or high-temperature conditions. It is designed for use in fire sprinkler and suppression piping systems where CPVC is the specified pipe material. Licensed sprinkler fitters and plumbing contractors are the primary installers of this fitting in both new construction and retrofit applications.

This adapter is intended for CPVC fire sprinkler systems operating at elevated temperatures and pressures typical of residential and light commercial suppression installations. The FlameGuard designation indicates the fitting meets fire protection piping standards and is suited for listed CPVC sprinkler systems. It serves as a transition point where a CPVC branch or main connects to a threaded component such as a sprinkler head, valve, or alarm device requiring a female NPT port.

Key Features

• 1-inch nominal size in Socket x FIPT configuration for threaded-to-solvent-weld transitions
• Brass thread insert reinforces the female threaded port for durable, leak-resistant connections
• CPVC construction rated for the higher temperature demands of fire suppression service
• FlameGuard product line designed to meet fire protection piping system requirements
• Socket end accepts standard 1-inch CPVC pipe with solvent cement per system specifications

Compatibility

Designed as an OEM-style fitting for use in listed CPVC fire sprinkler piping systems requiring 1-inch female adapter transitions with brass thread inserts.

Installation Notes

Installation should be performed by a licensed fire sprinkler contractor or journeyman plumber in accordance with NFPA 13, NFPA 13R, or NFPA 13D as applicable to the system design. Solvent-cement the socket end using a CPVC-compatible cement rated for fire sprinkler service and allow full cure time before pressurizing the system. Shut off and relieve system pressure before any fitting replacement or modification on an existing system. Do not over-torque the threaded port connection, as excessive force can crack CPVC fittings even with a brass insert present.
