Custom sealing gaskets can be manufactured by PSI for flanges from 3/8” diameter and up. For added flexibility and to accommodate a wide variety of flange types, sealing elements may be positioned anywhere between the I.D. of the bolt circle and I.D. of the gasket. In addition, PSI has designed and installed large diameter sealing gaskets with two sealing elements to provide maximum protection and reliability. Custom shaped gaskets can be manufactured to precise customer specifications for sealing mating surfaces of any configuration.

Standard gaskets for flanges as well as custom gaskets have been field proven by PSI in the following industries:

Wood and Pulp Processing Mills

Chemical Plants

Pipeline and Distribution Piping

Production Fields

Shipboard Installations

Electric Power Generation Plants

Steel Mills

LNG and SNG Systems

Petroleum Marketing Facilities

LineBacker™ Screened Gasket

The LineBacker Screened Gasket (shown above) is manufactured for “clean” natural gas service. It is designed to reduce the possibility of contaminates entering meters and other gas handling equipment. Recommended by rotary meter manufacturers for use upstream of their meters, the LineBacker Screened Gasket can be placed between your flanges without re-engineering or repiping.

LineBacker® Gaskets Used in Olympic Flame Tower
The traditional "lighting of the torch" concluded a two-hour opening ceremony celebrating the start of the 2002 Winter Olympic Games in Salt Lake City, Utah. While the identity of the "individual" who would light the flame had been kept a closely guarded secret, the crowd warmly greeted America's gold medal winning ice hockey team from 1980 with chants of "U-S-A" as they lit the flame.

The Olympic torch, designed and built by Wet Design, included 2-inch and 4-inch diameter 150ANSI LineBacker® gaskets. Chosen for their unmatched sealing reliability, LineBacker® gaskets were an integral part of a system that fueled an Olympic flame that was to burn brightly throughout the 2002 games.
