Add to compare

This is a new generation, ultra-low-temperature, and chemical-resistant elastomer that achieves outstanding low-temperature performance without compromising high-temperature performance. It is specifically formulated to meet and exceed the requirements of Aerospace Material Specification (AMS) 7379 and AMS-P-83461. This seal was developed as a true -65°F (-53°C) FKM elastomer to overcome existing limitations of comparable materials. It offers low-temperature FKM (-70°F/-57°C), high-temperature capabilities (450°F/232°C), excellent chemical compatibility, and exceeds AMS 7379 and AMS-P-83461 specification requirements. It is available in various products and shapes, including simple o-rings and metal-bonded jackets, and is ideal for applications requiring both extreme low-temperature and high-temperature performance.
