1/2 inch Clearloc Push to Fit Test Cap

1/2" Clearloc Push-to-Fit Test Cap – Temporary Termination for Pressure Testing and Isolation

The 1/2" Clearloc push-to-fit test cap is designed for temporary sealing of open pipe ends in residential and commercial plumbing systems. It is compatible with copper, PEX, and CPVC tubing and provides a tool-free method for pressure testing or system isolation prior to fixture or valve installation.

Technical Specifications

• Connection Type: Push-to-connect (1/2" nominal)
• Pipe Compatibility: ASTM B88 copper, ASTM D2846 CPVC, ASTM F876/F877 PEX
• Material: Lead-free brass body, EPDM O-ring, stainless steel grab ring
• Working Pressure: Rated for 200 PSI at 73°F
• Temperature Range: Suitable for service up to 200°F
• Certifications: Complies with ASSE 1061, NSF/ANSI 61 and 372; lead-free compliant

Applications

Used in plumbing systems for temporary sealing during pressure testing, air or water inspection procedures, or line isolation before fixture installation. Typical use cases include new construction, maintenance isolation, and rough-in stages of potable water system layout.

Installation Guidelines

Insert clean, square-cut pipe into the fitting until fully seated per the manufacturer’s insertion depth (e.g., 15/16" for 1/2" pipe). No adhesives, clamps, or tools are required. Removal is possible with an appropriate disconnect clip or tool. Test caps are reusable and intended for temporary use only—not for permanent sealing.

Performance Consideration

Push-to-fit test caps offer a pressure-rated alternative to threaded or solvent-welded terminations. The integrated stainless steel grip ring and O-ring seal deliver leak-tight performance under test conditions without additional sealing compounds or thread tape.
