Tripac Fasteners 1LGF8NANSF61/04 Full Face Gasket 4in 150

Product Description

The TRIPAC FASTENERS 1LGF8NANSF61/04 is a full face (FF) flange gasket designed for use in piping systems requiring a Class 150 pressure rating. It has a nominal pipe size of 4 inches and a thickness of 0.125 inches (1/8 inch). Constructed from non-asbestos gasket material, it provides a reliable, code-compliant sealing surface across the entire flange face. Plumbers, pipefitters, and mechanical contractors install this type of gasket wherever full face flanges require a complete, bolt-hole-to-bore seal. The non-asbestos composition meets current material safety standards and suits a broad range of fluid and gas service applications.

This gasket is suited for Class 150 flanged pipe connections at 4-inch nominal pipe size. Full face gaskets are commonly specified in cast iron flange systems, as well as other flange types where bolt loads must be distributed evenly across the entire face to prevent flange damage. Typical install scenarios include water distribution, HVAC hydronic piping, and general industrial process piping where Class 150 flat-face or full face flanges are used.

Key Features

• Nominal pipe size: 4 inches
• Thickness: 0.125 inches (1/8 inch)
• Pressure class: 150
• Sold as a single unit

Compatibility

Designed as an OEM-style replacement or new-installation gasket for Class 150 full face flanges at 4-inch nominal pipe size.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes such as the IPC or ASME B16.21 flange gasket standards. Depressurize and drain the piping system fully before removing any flanged connection. Inspect flange faces for damage or corrosion before seating the new gasket, and ensure bolt torque is applied evenly in a cross pattern to achieve uniform compression without over-stressing the gasket material.
