Primary industries


Inventory optimization and quick distribution

The production and processing of raw materials in primary metals and pulp and paper industry require large capacities and power transmission systems that meet the highest process requirements. Leader Gasket is the complete supplier of industrial gaskets tailored for primary metals.

Special solutions for aggressive chemicals used in this Industry as piping and pipelines and leach systems.  We provide inventory optimization, rapid distribution and increased efficiency of gaskets for many customers in primary industries via our allied distributor network across the globe.

Leader Spiral Wound Gasket SR & SRI

Spiral wound gaskets are still the most popular due to the wide variety of styles and sizes available. They can be fabricated of any metal which is available in thin strip and which can be welded; therefore, they can be used against virtually any corrosive medium dependent upon the choice of metal and filler.

Leader Elastagraph Corrugated Metal Graphite Gaskets

The corrugated gasket Elastagraph® designed for high performance, low leakage, graphite gaskets for standard flange or heat exchanger applications. Designed as an engineered solution for large diameter fixed equipment where leakage and low available load are issues. High performance replacement for asbestos, jacketed gaskets, spiral wounds and is a less expensive option as compared to a kammprofile gasket.
Elastagraph® standard pipe gaskets for EN and AMSE flanges provides improved leakage and sealability even at low bolt forces contributing higher performance on Flange Integrity.


This LeaderKAM Kammprofile Gasket is highly recognized as the problem solver for Heat Exchangers and Large Vessels. The Kammprofile provides the tightest seal combined with superior load bearing characteristics. This gasket design is made with a metal core and available with or without outer ring. The metal core with its concentric serrations can be faced with graphite, ePTFE or LeaderTHERM mica.

Leader Clipperlon modified PTFE

Leader Gasket’s Clipperlon range of modified PTFE sheet gasket are resistant to a broad range aggressive chemicals. In addition, they have an excellent gas-tightness and resistance to low temperatures and creep and flow. Clipperlon sheet gaskets are easy to handle and to be cut by hand in emergency cases. Some Clipperlon styles are also suitable for use in 100% sterile environments as in the food industry or pharmaceutical industry. For low to middle pressure systems Clipperlon is a universal pipe gasket in Chemical Industy.
