Kalrez® O-Rings and Seals

Chemical Processing

Proven Performance in the Chemical Processing Industries

Kalrez® o-rings and seals provide dependable long-term service in the chemical processing industry, including pharmaceuticals, petroleum refining, agricultural chemicals, and polymer production. In sealing applications that require high heat and aggressive chemical resistance, parts made from genuine Kalrez® perfluoroelastomer deliver increased reliability and safety, extended service life and design flexibility.

For long-term, reliable service Kalrez® perfluoroelastomer parts are a reliable, cost-effective sealing solutions. In aggressive chemical or thermally challenging environments, Kalrez® parts have been reducing downtime and extending the mean time between replacements (MTBR) in:

• Chemical production and transport
• Petroleum refining
• Agricultural chemicals manufacturing
• Painting and coating operations
• Analytical and process control instrumention

In pumps, valves, reactors, flange joints and other equipment, Kalrez® parts–whether they are O-rings, custom shapes or valve stem packing systems–are proving their value year-in and year-out. Their combination of long-term resistance to chemical attack, swelling and elevated temperatures allows chemical companies to reduce costly seal failures, improve MTBR, control fugitive emissions, improve process productivity and avoid contamination of the process stream.

KVSP®: The no-leak valve solution

You can improve valve performance, reduce maintenance costs and limit fugitive emissions from all types of manual and automatic control valves to less than 1 ppm with Kalrez® Valve Stem Packing Systems (KVSP).

Compounds
