1/2 Inch Clearloc Push to Fit Coupling

Legend Valve 457-485 Push-Fit Test Cap – 1" ClearLoc Termination for Pressure Testing

The Legend Valve 457-485 Push-Fit Test Cap is designed for temporary termination of 1" nominal pipe during pressure testing or system staging. Utilizing ClearLoc push-fit technology, it provides a secure mechanical seal compatible with copper, CPVC, and PEX tubing—eliminating the need for solder, cement, or mechanical fasteners during rough-in or inspection procedures.

This test cap features a clear visual confirmation window that ensures full pipe insertion. Constructed from lead-free engineered polymer and equipped with EPDM sealing elements, it supports potable water system compliance while simplifying field installation and removal. Ideal for rough-in testing, isolation, or phased system pressurization.

Installation Guidelines

Prepare the pipe by cutting square and deburring the edge. Mark the correct insertion depth and push the pipe into the fitting until fully seated and visible through the ClearLoc window. No sealants or torque tools are required. For removal, use the manufacturer’s recommended disconnect clip or tongs. Confirm proper engagement before pressurizing system per local code.

Application Scope

Used for pressure testing, isolation of pipe branches, and temporary termination of open lines during rough-in. Common in residential and commercial water supply installations, including manifold distribution, mechanical room layouts, and retrofit work requiring sealed, non-permanent endpoints.

Field Insight

Push-fit test caps offer labor savings and reduced error rates during staged inspections. Visual confirmation features like ClearLoc support faster inspection sign-offs and reduce potential for under-insertion. Their reusability also supports phased construction cycles with minimal component waste.

The Legend Valve 457-485 Push-Fit Test Cap is a contractor-grade solution for temporary line termination and pressure validation. Designed for performance, efficiency, and compliance, it’s a trusted component in modern plumbing system workflows.
