3/4 inch SDR 11 Con-Stab Pipe Adapter Male IPS

3/4 Inch SDR 11 Con-Stab Pipe Adapter – Male Iron Pipe Size (IPS)

The 3/4 inch SDR 11 Con-Stab Pipe Adapter (Male IPS) is designed for direct transition between polyethylene gas pipe and metal threaded connections. Manufactured for use in underground gas distribution systems, this mechanical fitting simplifies installation by eliminating the need for fusion equipment, while still maintaining compliance with regulated joint integrity standards.

System Application and Compatibility

This adapter is used with medium-density (MDPE) and high-density (HDPE) PE gas piping conforming to ASTM D2513, with a standard dimension ratio (SDR) of 11. It provides a mechanical connection to metal pipe or threaded valves via its male NPT outlet. Key design features include:

• ✅ Mechanical Compression Seal – Con-Stab end mechanically seals to the PE pipe without heat fusion; utilizes internal stiffener and elastomeric sealing components.
• ✅ Brass or Engineered Body Construction – Designed to resist corrosion, UV exposure (when applicable), and underground conditions.
• ✅ Male NPT Outlet – 3/4 inch MNPT threads comply with ANSI B1.20.1 for direct mating with steel pipe or fittings.
• ✅ SDR 11 PE Pipe Compatibility – Sized and tested for use with PE gas tubing with a wall thickness ratio of SDR 11.

Installation Guidelines

Cut the PE pipe square and deburr before insertion. No heat fusion or special fusion tools are required. Follow the manufacturer’s instructions for insertion depth, tightening torque, and visual verification. Use thread sealant or PTFE tape approved for gas service on the male threaded outlet. This fitting is intended for use only in gas service applications as specified by local codes and regulations.

Typical Use Cases

Commonly installed in underground gas service laterals, meter riser assemblies, and distribution systems requiring transitions from plastic to metal components. Applicable in utility, commercial, and residential natural gas or propane installations using approved PE piping systems.
