Oil and gas production and chemical manufacturing industries present sealing technologies with some of the harshest and most demanding operating environments.

Harsh and Demanding Operating Environments Require Chemically Resistant and Thermally Stable Seals

"We screen Kalrez against some of the most aggressive corrosive fluids," says Dr Christopher Bish, Technical Fellow. "And in addition to the fluid testing, we did some compression set testing and stress relaxation testing at high

DuPont™ Kalrez^® 7375 FFKM sealing products provide high temperature as well as broad chemical and water/steam resistance properties. Sealing performance, reliability and safety are ensured for applications in the most demanding industrial, chemical and general industrial fields of operation.

These high performance perfluoroelastomer O-ring components are available from Gallagher Fluid Seals, the authorized distributor for a wide range of DuPont™ finished O-rings, as well as custom shapes, sheets and cord sealing components.

The Kalrez^® 7375 parts are tailored for specialized chemical applications covering broad operating temperatures from -20°C to 300°C (-4ºF to 572ºF).

These products, which incorporate patented cross-linking technology, combine both superior chemical resistance with a thermal stability which exceeds many other competitive FFKM products. They are also available in most standard O-ring sizes including AS568, metric and JIS, with custom sizes and shapes also available on request.

Clean in Place Service Benefits from Kalrez® O-rings

Hilge-Pumpen AG, Swiss subsidiary of Philipp-Hilge GmbH, Bodenheim, Germany, selected Kalrez^® 6221 perfluoroelastomer parts to seal its Euro-Hygia^®, Hygiana-HT and Contra pump series, to meet the stringent safety, cleanliness and  sterilization requirements demanded by the pharmaceutical, biotechnology and cosmetics industries.

The Challenge

Pumps used in pharmaceutical, biotechnological and sterile processes are subject to some of the highest standards and safety requirements worldwide. In addition to ease of operation they must also provide maximum biological safety without any unfavorable hydraulic characteristics that could adversely influence sensitive products.

DuPont Performance Materials (DPM) is a leading innovator of thermoplastics, elastomers, renewable-sources polymers, high-performance parts and shapes, as well as resins that act as adhesives, sealants, and modifiers.

Gallagher Fluid Seals is a long-time partner of DuPont™, predominantly focusing on the Kalrez® line of products which is part of DPM. The latest perfluoroelastomer offering from DPM, Kalrez® Spectrum™ 7275, offers a higher level of sealing performance in the most aggressive chemical processing and manufacturing environments.

Gallagher Fluid Seals is a longtime partner of DuPont®’s, having specified thousands of DuPont perfluoroelastomer parts over the past few decades.

While elastomers were originally created as an alternative to natural rubber, they have expanded to include materials such as high-performance perfluoroelastomers for demanding applications.

These materials can also be used in place of plastics in most, if not all, applications. DuPont is at the forefront of perfluoroelastomer development, creating elastomers with properties that can help meet highly specific application requirements.

Read on to learn more from Dupont about the differences between elastomers and plastics, and how elastomeric seals perform compared to plastic seals.
