1-1/2 inch Carbon Steel 401G Gas Press Coupling with Stop Press x Press

1-1/2" Carbon Steel 401G Gas Press Coupling with Stop – Press-to-Connect Solution for Fuel Gas Systems

The 1-1/2" Carbon Steel 401G Gas Press Coupling with Stop is a mechanical press fitting engineered specifically for joining carbon steel pipe in fuel gas distribution systems. Designed to meet the demands of commercial and industrial installations, this fitting offers a safe, heat-free method of connection that maintains pressure integrity without the need for threading or welding.
The built-in stop feature ensures precise pipe alignment during insertion, reducing installation errors and promoting consistent joint quality in the field.

This coupling is part of the Apollo PowerPress® 401G series, developed for use with Schedule 40 carbon steel pipe in gas systems. It is factory-fitted with HNBR sealing elements and is compatible with standard press tools and V-profile jaws commonly used by professionals in mechanical and gas piping trades.

Technical Advantages

• ✅ Material: ASTM A420 carbon steel body with zinc-plated corrosion-resistant finish
• ✅ Seal Type: HNBR O-ring pre-installed for hydrocarbon gas compatibility
• ✅ Connection Method: Press x Press with pipe stop for controlled insertion depth
• ✅ Leak Detection: Incorporates Leak Before Press® feature for visual testing verification
• ✅ Temperature/Pressure Range: Rated for up to 250 psi at -40°F to 180°F in gas service

Installation Guidelines

Proper installation requires the use of calibrated press tools and manufacturer-approved jaws. Pipes should be cut square, deburred, and marked to the insertion depth prior to pressing. Do not use thread sealant or tape with press connections. Follow all local and national fuel gas codes (e.g., NFPA 54, ANSI Z223.1) and manufacturer's installation instructions to ensure compliance and performance.

Application Areas

This fitting is used in fuel gas piping systems including:

• Commercial and industrial natural gas distribution
• LP gas piping in mixed-use buildings
• Boiler and mechanical room installations
• System retrofits and gas piping expansions

Product Use and Compliance

All 401G series gas press fittings are independently tested and certified for gas applications. This includes compliance with ANSI LC 4/CSA 6.32 standards. The HNBR seal is suitable for use with natural gas, propane, and other approved hydrocarbon gases within specified limits.

Advantages in the Field

• ✅ Reduced Labor Time Enables faster installations compared to welded or threaded systems
• ✅ No Open Flame Eliminates fire risk and hot work permits during installation
• ✅ Repeatable Performance Minimizes joint variability and field failures

The 1-1/2" Carbon Steel 401G Gas Press Coupling with Stop delivers a secure, code-compliant connection for fuel gas systems. Its press-fit design and integrated stop simplify alignment and accelerate workflow, while the HNBR sealing element ensures safe performance under demanding conditions. This is a proven solution for professionals requiring speed, safety, and consistency on high-stakes gas piping jobs.
