1/2 inch Carbon Steel 417G Gas Press Cap

1/2" Carbon Steel Gas Press Cap – Model 417G

The 1/2 inch Carbon Steel 417G Gas Press Cap is designed to terminate unused press connections in fuel gas piping systems. Manufactured from carbon steel and engineered for use in conjunction with press-fit carbon steel piping components, this cap provides a permanent, flame-free method of sealing branch lines or system extensions.

Product Overview and Material Characteristics

This press cap features a cold-formed body with a factory-installed sealing element and defined press contour, compatible with standard carbon steel press systems. It is intended for use in natural gas and propane distribution within commercial and residential systems and meets relevant fuel gas system standards.

• ✅ Carbon Steel Construction Fabricated from high-strength carbon steel conforming to ASTM specifications for gas distribution components.
• ✅ Press Connection Press-fit design eliminates the need for threading, welding, or soldering, enabling quick installation with approved press tools.
• ✅ Leak Detection Capability Compatible with tool-actuated leak detection features during system testing.
• ✅ Internal Sealing Element Typically EPDM or HNBR depending on application type; rated for gas service conditions.

Technical Specifications

• Size: 1/2 inch nominal
• Material: Carbon Steel
• Connection Type: Press (standard profile)
• Application: Fuel gas systems (natural gas, propane)
• Standards: Meets ANSI LC-4 / CSA 6.32, ICC, and NFPA 54 requirements

Installation Notes

Install using manufacturer-recommended press tools and jaws specific to the system size and press profile. Ensure pipe is deburred and insertion depth is marked prior to pressing. No sealant or thread tape is required. Pressed joints should be pressure tested per local code. Not suitable for use in potable water or compressed air systems.

Typical Applications

The 417G press cap is used to terminate branch lines or unused outlets in fuel gas piping networks. It is frequently employed during phased construction, system modifications, or permanent sealing of unused ports in manifolds, appliance connections, or risers.

System Compatibility

Designed for integration with carbon steel press systems rated for fuel gas, this cap offers mechanical strength and leak-resistance in non-potable, high-pressure environments. Suitable for both above-ground and concealed installations as allowed by code.

The 1/2" Carbon Steel 417G Gas Press Cap offers a secure, fast-install solution for terminating press system ends in gas service piping. Engineered for compliance and repeatable performance, it supports contractor-grade reliability on job sites requiring code-compliant fuel gas solutions.
