1-1/4 inch Carbon Steel 400G Gas Press Coupling with Stop Press x Press

1-1/4" Carbon Steel Gas Press Coupling with Stop – Press x Press Fitting for Fuel Gas Systems

The 1-1/4" Carbon Steel Gas Press Coupling with Stop is a precision-engineered mechanical fitting designed for use in fuel gas piping systems. Manufactured from durable carbon steel and equipped with press ends, this coupling allows for fast, flame-free connections in black steel piping systems compliant with ANSI Z223.1/NFPA 54 standards.

Its integral stop feature ensures correct pipe insertion depth and alignment during installation, promoting joint integrity and consistent performance under pressure. This coupling is part of a press fitting system compatible with carbon steel pipe and is suitable for use in both new construction and retrofit gas piping projects.

Key Features and Performance Attributes

• ✅ Carbon Steel Body Made from ASTM A420 or equivalent material for structural integrity and corrosion resistance in gas service environments.
• ✅ Press Connection Technology Eliminates the need for threading or welding, reducing labor time and minimizing fire risks on job sites.
• ✅ Stop Feature Internal pipe stop ensures proper pipe alignment, aiding in consistent sealing and avoiding over-insertion.
• ✅ Sealing Element Pre-installed HNBR sealing ring rated for fuel gas applications, providing reliable leak resistance.
• ✅ Code Compliance Approved for use in gas distribution systems under IAPMO, CSA, and ICC listings where applicable.

Installation Requirements

Press connections must be made using manufacturer-approved press tools with calibrated jaws. Ensure pipe ends are cut square, deburred, and marked for insertion depth prior to pressing. This fitting does not require thread sealant or tape, as sealing is achieved through the O-ring and mechanical deformation of the press sleeve.

Technical Specifications

• Material: Carbon Steel
• Size: 1-1/4" Nominal
• Connection Type: Press x Press with Stop
• Sealing Element: HNBR (Hydrogenated Nitrile Butadiene Rubber)
• Pressure Rating: Up to 125 psi (Gas), System rated 400G
