Legend Valve 441-090p 3 Inch Csg Coupling with Stop

Product Description

The LEGEND VALVE 441-090p is a 3-inch corrugated stainless steel (CSG) press coupling with an integrated stop, designed for joining fuel gas and compressed air distribution lines. The stop feature ensures consistent pipe insertion depth during assembly, reducing the risk of incomplete connections. Rated for 125 PSI maximum on fuel gas and 200 PSI maximum for air, this fitting meets ANSI LC 4a and CSA 6.32 standards. Licensed plumbers and gas fitters install this type of fitting in both new construction and retrofit piping systems where press-connection tooling is used in place of threaded or soldered joints.

This coupling is suited for residential and light commercial gas distribution applications where corrugated stainless steel flexible gas piping systems are specified. The Large Press x Large Press configuration allows direct connection of two CSG pipe runs at 3-inch diameter. Its rated operating temperature range of -40 degrees F to 180 degrees F makes it appropriate for interior mechanical rooms, utility spaces, and similar environments where gas piping is routed to appliances, boilers, and other equipment.

Key Features

• Integrated pipe stop ensures consistent and complete insertion depth for reliable press connections
• Rated 125 PSI maximum for fuel gas service
• Rated 200 PSI maximum for compressed air service
• Operating temperature range: -40 degrees F to 180 degrees F
• Meets ANSI LC 4a and CSA 6.32 standards
• Large Press x Large Press end configuration for direct CSG-to-CSG joining

Compatibility

Designed for use with 3-inch corrugated stainless steel gas piping systems using large press-style end connections, in applications conforming to ANSI LC 4a and CSA 6.32 requirements.

Installation Notes

Installation of gas piping fittings must be performed by a licensed plumber or gas fitter in accordance with local codes, IFGC requirements, and the CSG piping manufacturer's guidelines. Shut off the gas supply and verify zero pressure in the line before making or breaking any connections. Press connections require a compatible press tool and jaw set rated for the fitting size and end type — do not substitute tools not approved for this fitting profile. After assembly, pressure-test the completed system per applicable code before returning it to service.
