1 inch Con-Stab SDR11 Gas Coupling IPS

1 Inch Con-Stab SDR11 Gas Coupling – IPS, ASTM D2513 Compliant Mechanical Fitting

The 1 inch Con-Stab SDR11 Gas Coupling is a mechanical fitting used to join medium-density (MDPE) or high-density (HDPE) polyethylene gas pipe with a standard dimension ratio (SDR) of 11. Designed for use in underground natural gas and propane distribution systems, this fitting provides a non-threaded, stab-type compression connection for IPS-sized piping. It meets applicable performance and safety standards for direct burial and regulated fuel gas applications.

Material and Compliance Information

This coupling is constructed from engineered polymer materials and corrosion-resistant internal components to ensure compatibility with polyethylene gas pipe systems. It is tested to meet the mechanical integrity and leak-resistance standards required for use in utility and municipal gas distribution networks. Key features include:

• ✅ Material: UV-resistant high-performance polymer body with stainless steel gripper ring and sealing components
• ✅ Connection Type: Con-Stab (stab-type mechanical fitting) for 1 inch IPS SDR11 PE pipe
• ✅ Pressure Rating: Suitable for gas systems operating up to 125 psi (per ASTM D2513)
• ✅ Compliance: Conforms to ASTM D2513 Category I; typically qualified to ANSI B31.8 and DOT Part 192

Installation Guidelines

The fitting is designed for cold installation—no heat fusion, threading, or adhesives required. Cut the PE pipe squarely, chamfer the end, and stab into the fitting until fully seated. A visual indicator confirms proper insertion depth. Use manufacturer-approved chamfer tools and follow all field procedures and pressure test protocols required by the gas utility or authority having jurisdiction (AHJ).

Typical Applications

Used in below-grade gas distribution systems for residential and light commercial service. Typical installations include riser-to-main connections, lateral service branches, and pipe extensions for outdoor appliances or meter assemblies. Compatible with polyethylene pipe used in new construction or replacement applications.

Note on Pipe Compatibility

Ensure SDR compatibility (SDR11 only) and correct pipe material (MDPE or HDPE) before installation. Use only fittings listed by the manufacturer for gas applications and verify third-party listings or utility approvals as required for regulated systems.
