1-1/4 inch SDR 11 Con-Stab Pipe Adapter Male IPS

1-1/4" SDR11 Con-Stab Pipe Adapter – Built for Gas Distribution Performance

Designed for secure polyethylene (PE) gas pipe connections, the 1-1/4" SDR11 Con-Stab Pipe Adapter provides a robust transition between PE pipe and male iron pipe threads (MIP). Manufactured for use in underground gas distribution systems, this fitting delivers dependable performance where safety and durability are critical.

Product Features

• ✅ Electrofusion-Free Installation – Uses stab-type mechanical compression connection, eliminating the need for heat fusion tools.
• ✅ Engineered Polymer Body – Constructed from high-performance materials resistant to environmental stress cracking and corrosion.
• ✅ Integrated Internal Sealing Components – Dual-seal design ensures long-term gas-tight integrity under system pressures.
• ✅ SDR11 Compatibility – Designed for use with 1-1/4” SDR11 PE pipe in accordance with ASTM D2513.
• ✅ Threaded Male Outlet – NPT iron pipe threads allow direct connection to metal fittings or regulators.

Technical Specifications

• Pipe Size: 1-1/4" SDR11
• Outlet: 1-1/4" Male Iron Pipe Thread (NPT)
• Material: Engineered thermoplastic (body), stainless steel stiffener
• Connection Type: Con-Stab compression (inlet) x MIP (outlet)
• Standard Compliance: ASTM D2513, CSA B137.4, DOT CFR 49 Part 192
• Pressure Rating: Suitable for gas distribution systems at up to 125 psi

Installation Guidance

Con-Stab fittings require no special tools, but correct insertion depth, pipe preparation, and alignment are critical to maintain seal integrity. Use of an internal pipe stiffener is mandatory for SDR11 installations. Ensure the pipe end is square-cut, chamfered, and free of debris before insertion. Over-tightening the threaded outlet may compromise seal performance—tighten to manufacturer-recommended torque specifications.

Common Applications

• Natural gas and propane distribution systems
• Service lines connecting PE pipe to residential or commercial structures
• Transitioning from plastic piping to steel piping at riser points

Contractor Note

This adapter is purpose-built for underground gas applications and should be installed per local code and utility specifications. Always confirm compatibility with your piping system's SDR rating and material before installation.

Engineered for performance and ease of installation, the 1-1/4" SDR11 Con-Stab Pipe Adapter is a reliable solution for contractors requiring consistent, code-compliant connections in gas piping systems. Its robust construction and field-proven design ensure lasting service in demanding environments.
