This material stands up to ozone, extrusion under high pressure, and impact and shock loading. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with hot water and steam or ketones.
It sees regular use in off-highway equipment, high-pressure fluid power, and mining and heavy equipment.
