1 inch x 3/4 inch Carbon Steel 418G Gas Press Reducing Fitting Male x Press Carbon Steel

1" x 3/4" Carbon Steel Press Reducing Fitting – Gas-Approved, 418G Pattern

The 1" x 3/4" carbon steel press reducing fitting (418G profile) is a transition component used in press-connect gas piping systems. Manufactured to meet specifications for fuel gas distribution, this fitting allows for a secure reduction from 1" to 3/4" nominal pipe sizes while maintaining code-compliant performance under system operating pressures.

Constructed from carbon steel with corrosion-resistant coating, this press fitting is designed for use with schedule-based carbon steel pipe and is installed using compatible press tools. Its leak-before-press (LBP) feature ensures installation accuracy during pressure testing.

Performance and Construction Features

• ✅ Material: Carbon steel with zinc-nickel coating or equivalent corrosion-resistant finish
• ✅ Connection Type: Press x Press, 1" (run) x 3/4" (branch) nominal sizes
• ✅ Application: Fuel gas distribution systems conforming to ANSI LC 4 / CSA 6.32
• ✅ Leak Detection Feature: Leak-before-press design for visual leak verification during pressure testing
• ✅ Sealing Element: Pre-installed HNBR sealing ring rated for gas and temperature fluctuations

Installation Guidelines

Installation requires a press tool with manufacturer-approved jaws. The fitting should be properly deburred, marked for insertion depth, and pressed according to tool specifications. Ensure alignment and avoid rotating or stressing the fitting post-installation. All connections must be verified per local code, and pressure testing should be conducted before commissioning.

Approved Use Cases

This press reducing fitting is used in natural gas and propane piping systems in residential, commercial, and industrial installations. Typical applications include branch takeoffs, appliance connections, and line transitions within fuel gas distribution networks.

Code and Material Compliance

Manufactured in accordance with ISO 7/1 and tested to conform with fuel gas codes including the International Fuel Gas Code (IFGC) and NFPA 54. Also listed to applicable ASTM standards for press fittings in fuel gas systems. Not for use with potable water or oxygen applications.
