1-1/2 inch Carbon Steel 417G Gas Press Cap

1-1/2" Carbon Steel Press Cap – Gas Rated, EPDM Sealing Element

The 1-1/2 inch Carbon Steel Gas Press Cap is designed to terminate unused ends of piping in press-connect gas distribution systems. Constructed from zinc-plated carbon steel and factory-fitted with a yellow HNBR sealing element, this press cap ensures a secure, permanent closure point in natural gas and fuel gas piping applications. Intended for use with compatible press tools and jaws conforming to approved press profiles.

Design and Material Specifications

• ✅ Material: Carbon steel (zinc-plated for corrosion resistance in non-buried installations)
• ✅ Sealing Element: Yellow HNBR (Hydrogenated Nitrile Butadiene Rubber) for fuel gas compatibility
• ✅ Connection Type: Press-fit (mechanical joint using press tools)
• ✅ Pressure Rating: Suitable for fuel gas applications per ANSI LC 4 / CSA 6.32 (press systems)
• ✅ Size: 1-1/2 inch nominal pipe size

Installation Requirements

Before installation, verify pipe ends are properly deburred and marked for insertion depth. Install the fitting using press tools approved by the manufacturer. The cap must be pressed over properly prepared carbon steel pipe ends, and sealing integrity should be confirmed visually through indicator markings. This fitting does not require threading, welding, or heat application.

Applications

Commonly used to terminate branches or unused outlets in:

• Fuel gas distribution systems (natural gas and propane)
• HVAC systems and appliance lines
• Residential and commercial gas manifolds
• Retrofitted press systems replacing traditional threaded or welded closures

Standards and Compliance

This press cap meets or exceeds performance requirements set by applicable fuel gas system codes and standards, including:

• CSA LC 4 / CSA 6.32 (Press-Connect Metallic Fittings for Gas)
• ICC-ES PMG Listings where applicable
• ASTM and ANSI/ASME dimensional tolerances for Schedule piping systems

The 1-1/2" Carbon Steel Gas Press Cap provides a fast, flame-free method for sealing gas piping system terminations, helping contractors reduce labor time while maintaining code compliance and mechanical integrity.
