491 DIN Rotary Internal Single Seal (Global)
- General Purpose, Single Component Seal
The 491 is designed in accordance with EN 12756 to fit the short length installation requirements.
The 491 is designed not to damage or fret the equipment shaft/sleeve because the dynamic O-Ring is positioned on a replaceable component surface. This balanced, high-pressure monolithic seal design will provide a performance upgrade to standard, original equipment component seals. The seal can be easily rebuilt in the field using low-cost rebuild kits.
