The Kalrez® Application Guide for Aircraft and Aerospace is designed to aid engineers in the proper selection of Kalrez® products for aircraft and aerospace applications, and the proper seal design with these products. If additional assistance is needed, application engineers are available to aid in the material selection and seal design.


The Kalrez® Application Guide - Aero (KAG-Aero) is divided into three segments: Product Selection, Seal Design, and O-Ring Troubleshooting.

Product Selection

In the Product Selection section, Kalrez® products are rated in a variety of temperatures and chemical media. Specific compounds have been developed to meet the unique needs of the aircraft and aerospace industry.

Seal Design

The Seal Design section is organized to assist users in designing seals for O-rings or choosing o-rings for specific seals. The user has several seals to choose from which cover standard O-ring designs. These seals can be designed for specific O-rings or an o-ring can be selected for a seal of specific dimensions.

O-ring Troubleshooting

The O-ring Troubleshooting section includes photos of O-rings damaged from chemical, thermal, or mechanical attack. By understanding the cause of O-ring failure, proper selection of an alternative elastomer or seal design can help improve seal life.
