This type is intended for dynamic service and shipboard fluids except superheated steam or other service resulting in packing temperatures of over 450°F oxygen, molten alkaline metals, or fluorochemicals. Pressures should not exceed 150 pounds per square inch (lb/in²) at the packing, and rod or shaft speed should not exceed 1,500 feet per minute (ft/min).

This type is intended for static to low speed or intermittent service and shipboard fluids except superheated steam or other services resulting in packing temperature of over 450°F, oxygen, molten alkaline metals, or fluorochemicals. Pressures should not exceed 2,500 lb/in² and rod or shaft speeds should not exceed 25 ft/min.

This type is intended for static to low speed or intermittent service against oxygen. Pressures should not exceed 2,500 lb/in² and rod or shaft speed should not exceed 25 ft/min. Packing must be kept absolutely clean and uncontaminated in any way.
