Note: the use of temperature range is affected by sealing medias, use conditions, required performance and other factors.

* Max. T: This value accounts the results of air heating degradation testing. The number shown in ( ) is the heat-resistant

temperature under temporary use, should be avoided for a long period of continuous use.
* Min. T: Suit for TR10. TR is Temperature-Retraction, indicating the recovery of deformation in low temperature. TR10 value refers to the pre-given temperature when deformation recovery 10%, is the standard value of low temperature service limit.
