1 Inch Stainless Steel Insert Coupling – Barbed Connection for Polyethylene Systems

The 1 inch stainless steel insert coupling is designed for use with flexible polyethylene (PE) piping in cold water distribution systems. This coupling features barbed ends to accommodate mechanical connection using stainless steel clamps or crimp rings. Its durable construction and corrosion-resistant properties make it suitable for underground and above-ground applications where high-strength, non-corrosive fittings are required.

Material and Design Features

Manufactured from lead-free stainless steel, this insert coupling supports secure connections in systems subject to variable pressure and environmental conditions. Its dual insert profile allows for consistent flow performance and mechanical stability across joined pipe sections.

• ✅ Barbed Insert Ends Compatible with ASTM D2239/D2737 polyethylene tubing for secure mechanical coupling.
• ✅ Lead-Free Stainless Steel Provides excellent resistance to pitting, chemical degradation, and scale formation.
• ✅ High Tensile Strength Maintains structural integrity in buried and exposed service conditions.
• ✅ Corrosion-Resistant Surface Suitable for use in non-potable water, irrigation, and some potable water applications where approved by code.

Installation Guidelines

To ensure a secure seal, use stainless steel worm gear clamps or crimp bands rated for polyethylene piping. The pipe must be cut square and fully inserted onto the barbs before clamp placement. Tighten the clamp over the barbed region to the recommended torque to prevent joint failure under pressure. This fitting does not require soldering or adhesive.

Common Applications

Used in cold water service lines, irrigation systems, and municipal service applications. Also specified in certain low-pressure fluid distribution systems in agricultural and commercial environments. Appropriate for both permanent and serviceable installations.

Code Compliance

Stainless steel insert couplings must meet NSF/ANSI 372 for lead-free content when used in potable water systems. Installation must comply with local codes, including proper identification and documentation when used in regulated water supply applications.
