High-Temperature Silicone O-Rings These silicone O-rings withstand temperatures up to 400° F or 450° F. High-Temperature Soft Silicone O-Rings Able to withstand temperatures up to 400° F, these O-rings are softer than standard silicone O-rings for a better seal in low-pressure applications. Square-Profile High-Temperature Silicone O-Rings
Selection of O-Ring materials with inherently poor compression set properties. Improper gland design. Excessive temperature development, causing the O-Ring to harden and lose its elastic properties. (High temperatures may be caused by system fluids, external environmental factors or frictional heat build-up.)

Functional tests indicate that O-rings will usually provide reliable dynamic sealing at or below the TR-10 value. Static O-rings normally function satisfactorily to about -8°C (15°F) below this. Temperature at the TR-10 point should be taken for all elastomers to determine a minimum functional temperature.
