MIL-R-6855 Extrusions
What is MIL-R-6855?
MIL-R-6855 is a military specification that defines performance requirements for synthetic rubber sheets, strips, molded parts, and extrusions used in critical defense and aerospace applications. This specification ensures rubber products meet stringent standards for:
- Temperature resistance (-65°F to +250°F for Class 1, -40°F to +200°F for Class 2)
- Oil and fuel resistance
- Compression set resistance
- Tensile strength and elongation
- Ozone and weather resistance
- Consistent durometer readings
The specification includes two primary classes:
- Class 1 (Type A): High-temperature resistant rubber (typically silicone-based)
- Class 2 (Type B & C): Oil-resistant rubber (typically neoprene or nitrile-based)
