Junta enrollada en espiral API 601 de alta resistencia con anillo de centrado para bridas Inch 4 Inch libras; Stainless Steel 304 con relleno de grafito flexible; banda amarilla con rayas grises; diseñada para altas temperaturas y ciclos térmicos

Heavy Duty Spiral Wound Gasket with Center Ring, 4 in 150#
✔️ 4 in flange, 150# class, 304 stainless windings, graphite filler 1 pc

This spiral wound gasket is built for ASME B16.20 compliance on ASME B16.5 Class 150 flanges. It uses 304 stainless steel windings with a flexible graphite filler for reliable sealing in high temperature service and during repeated thermal cycles. The center ring locates the gasket precisely on the flange face, adds radial strength, and acts as a compression limiter to protect the flange.

💡 What is a gasket used for in piping systems?

Gaskets seal flange joints in high temp and pressure service to prevent leaks and accommodate thermal cycling.

• Seals joints between flange faces to prevent leaks under pressure and high temp
• Compatible with ASME B16.20 and B16.5 Class 150 flanges
• Spiral wound construction with graphite filler handles thermal cycling
• 304 stainless steel windings resist corrosion in harsh environments
