3/4 inch Con-Stab SDR11 Gas Coupling IPS

2881002 Wal-Rich 3/4" IPS Con-Stab Coupling – SDR11 Polyethylene Gas Line Fitting

The 2881002 Wal-Rich Coupling is a 3/4" IPS Con-Stab (constant stab) mechanical fitting used for joining medium-density polyethylene (MDPE) gas pipe in underground and outdoor fuel gas distribution systems. Manufactured to SDR11 specifications, this coupling is engineered for use in natural gas and propane installations, offering a dependable transition between polyethylene pipe segments without the need for fusion equipment.

This fitting features an integrated stab design with internal gripping and sealing mechanisms, enabling fast installation while maintaining a leak-resistant, code-compliant connection. No external heat source or fusion tools are required, significantly reducing time on site and minimizing joint variability.

Product Features

• ✅ SDR11 Compatibility Designed for use with 3/4" IPS MDPE gas pipe rated to ASTM D2513 specifications.
• ✅ Con-Stab Connection Mechanical insertion design provides a secure joint with positive pipe retention and integrated O-ring sealing.
• ✅ Steel Stiffener Included Internal support insert maintains dimensional stability and prevents pipe collapse at the joint.
• ✅ Tool-Free Assembly Requires no heat fusion or clamping—installs using manufacturer-recommended stab depth gauge and chamfer tool.
• ✅ Leak-Resistant Seal Elastomeric sealing system ensures long-term gas-tight performance when installed per specifications.

Technical Specifications

• Model: 2881002
• Nominal Size: 3/4" IPS
• Material: High-strength polymer body with internal stainless steel and elastomeric components
• Connection Type: Con-Stab (stab fitting for SDR11 PE pipe)

• Applicable Standards: ASTM D2513, DOT CFR Title 49 Part 192 (as applicable)

Installation Guidelines

Cut and chamfer the PE pipe using the recommended chamfer tool. Confirm insertion depth with a depth gauge and mark the pipe accordingly. Insert pipe into the coupling until the mark aligns with the edge of the fitting. Do not reuse Con-Stab fittings once assembled. All joints should be leak-tested per NFPA 54 and local code requirements before pressurizing the system.

Typical Applications

This coupling is used in underground gas service lines, meter riser assemblies, utility trenching, and branch tie-ins for both residential and commercial fuel gas systems. It is suitable for installations requiring a fast, non-fusion joining method under field conditions where safety and time efficiency are critical.

Note on Compliance

Con-Stab fittings must be installed by qualified personnel in accordance with manufacturer instructions and utility specifications. Use only with SDR11 MDPE piping intended for gas service.

The 2881002 Wal-Rich Con-Stab Coupling provides a secure, mechanical joint solution for gas service lines requiring SDR11 compliance. Its tool-free installation and integrated sealing technology offer a reliable alternative to fusion joining methods in polyethylene gas piping systems.
