2 inch Con-Stab SDR11 Gas Coupling IPS

2881010 SDR11 2" IPS Con-Stab Coupling – Mechanical Fitting for Poly Gas Pipe

The 2881010 Coupling SDR11 2" IPS Con-Stab is a mechanical compression fitting designed for joining medium-density (MDPE) and high-density (HDPE) polyethylene gas piping systems. It features a stab-type design that streamlines the installation process by eliminating the need for fusion welding or heat fusion equipment.

This coupling complies with ASTM D2513 requirements and is rated for use in underground gas distribution systems. The Con-Stab (compression-stab) technology provides a positive seal using internal grip rings and elastomeric components, ensuring mechanical joint integrity under operating pressure ranges defined by SDR11 specifications.

Key Product Attributes

• ✅ For 2" IPS SDR11 PE Pipe – Compatible with standard dimension ratio polyethylene piping used in gas distribution.
• ✅ Stab-Type Mechanical Connection – No fusion equipment required; uses an internal gripping mechanism and sealing element for secure assembly.
• ✅ Pressure Rating: Suitable for systems up to 125 PSI when used with SDR11 pipe and installed per manufacturer instructions.
• ✅ Compliance: Meets ASTM D2513 and DOT CFR Title 49 Part 192 for gas distribution components.
• ✅ Materials: Constructed from corrosion-resistant components compatible with underground installation.

Installation Guidelines

Installation requires proper pipe preparation, including cutting square, chamfering, and cleaning per coupling manufacturer’s instructions. Pipe must be inserted to the proper stab depth to engage the internal sealing and restraint components. Visual or depth markings should be verified to ensure full engagement.

Common Use Cases

Used extensively in underground natural gas and propane distribution networks, this coupling is appropriate for mainline connections, service laterals, and repair scenarios. It supports direct burial in accordance with utility and pipeline construction standards.

Note on System Integrity

All mechanical connections should be field-tested at operating pressure and meet local inspection requirements. Proper storage, handling, and installation of polyethylene pipe and fittings are essential to maintain system certification and performance.
