Finally got these in for a high-temp pneumatic seal on a steam valve, and the -15°F to +400°F rating covers my needs perfectly. The 75 durometer brown material feels robust and seated easily in the groove.

I was worried the 0.139" cross-section might be too thick, but it seated perfectly in the groove and the 75 Durometer feels solid. Handles the high-temp service range of -15°F to +400°F exactly as needed for my application.

These fit perfectly on a hydraulic cylinder I was rebuilding. The 75 durometer feels like a good balance between flexibility and durability for this application.
