Overview

This spiral wound gasket is engineered for high-pressure sealing in demanding industrial piping and vessel applications. It is constructed with alternating layers of 316L stainless steel and PTFE (polytetrafluoroethylene), combining mechanical strength with superior chemical resistance. The design incorporates integral inner and outer containment rings, which provide stability during installation and prevent gasket over-compression or blowout under pressure fluctuations. It is manufactured to conform to common international flange standards, ensuring a precise fit and reliable performance in critical sealing environments.

Key Features

Robust construction with 316L stainless steel windings for strength and corrosion resistance PTFE filler layer provides excellent resistance to a wide range of chemicals and solvents Inner and outer reinforcing rings control compression and improve gasket handling Designed for high-pressure applications up to 232 PSI Suitable for use with standard raised face and flat face flanges Prevents flange rotation and minimizes creep relaxation under load

Specifications

Material: 316L Stainless Steel and PTFE Bore Diameter: 1.02 inches Overall Thickness: 0.18 inches Pressure Rating: 232 PSI Temperature Range: Up to 500°F (with PTFE filler) Construction: Spiral wound with inner and outer containment rings Pack Quantity: 36

Applications

Sealing pumps, valves, and compressors in chemical processing High-pressure steam and utility lines in power generation Flange connections in oil and gas pipelines and refineries Heat exchangers, reactors, and pressure vessels General industrial maintenance for leak prevention on standard flanges

Frequently Asked Questions

What are the exact dimensions and pressure rating for this spiral wound gasket?
This gasket has a 1.02 inch bore diameter, is 0.18 inches thick, and is rated for PN16 pressure class (approximately 232 PSI at 100°F). It is constructed with 316L stainless steel windings and filler, and a PTFE (Teflon) outer wrap for chemical resistance.
What are the typical applications for this specific type of gasket?
This D-type gasket with inner and outer rings is designed for sealing flanged connections in piping systems handling corrosive chemicals, high-purity fluids, or where contamination must be avoided. It is suitable for use in chemical processing, pharmaceutical, and food & beverage applications up to 500°F.
How is this gasket packaged and what is the minimum order quantity?
This gasket is packaged in quantities of 36 pieces per bag or box. The standard pack size is 36, which is also the minimum order quantity for this specific DN20 (1.02 inch bore) size and configuration.
