1/2" PEX Ear Clamp, Stainless Steel

3/4" PEX Stainless Steel Clamp – For Secure Crimp-Free PEX Connections

The 3/4" PEX stainless steel clamp is a mechanical fastener used for joining PEX tubing to barbed fittings in potable water and hydronic heating systems. Designed for use with ASTM F2098 clamp-style connection methods, it delivers uniform compression around the tubing to ensure a secure, leak-resistant seal without the need for solder, glue, or threading.

Technical Specifications

• Material: 304 stainless steel – corrosion-resistant and lead-free
• Size: 3/4" nominal clamp width
• Standard: Meets ASTM F2098 requirements for PEX clamping systems
• Tool Compatibility: Requires a calibrated clamp tool approved for ASTM F2098 applications
• Application Range: Designed for use with 3/4" PEX tubing and corresponding ASTM F1807/F2159 insert fittings

Applications

Commonly used in residential and light commercial plumbing systems, including water supply, radiant heating, and distribution manifolds. Ideal for confined spaces or projects where flame-free installation is required. Also suitable for system expansions, retrofits, and repairs where quick installation and mechanical reliability are priorities.

Installation Notes

Install by placing the clamp over the PEX tubing and fully inserting the fitting. Position the clamp 1/8" to 1/4" from the tubing end and compress using an ASTM-compliant clamp tool. Visual inspection of the clamp ear confirms proper installation. No additional sealant is required. All connections should be pressure-tested according to applicable codes after assembly.

Performance Consideration

Stainless steel clamps offer enhanced resistance to corrosion and environmental degradation, making them suitable for use in both indoor and exposed locations. Their one-piece construction allows for uniform tension and reduces the risk of localized leaks due to uneven compression.
