Overview
The Parker SEAL-H1L5-9511 is a rotary shaft Clipper oil seal manufactured by Parker Hannifin Corporation. The H1L5 material designation indicates an NBR (nitrile) lip compound. This general-purpose seal combines a molded elastomer lip with a reinforced composite rubber and aramid fiber outer diameter (heel) to create a durable, leak-free seal for industrial and mechanical power transmission applications.
Key Features
- Non-metallic, composite rubber/aramid fiber OD or “heel” forms a leak-free, press fit in the housing, conforming to minor surface irregularities
- Garter spring provides constant, uniform load of the lip on the shaft for the life of the seal, keeping the elastomer lip in contact with the shaft during higher shaft speeds and offsetting normally occurring compression set and wear
- Excellent retention of grease and light oil splash
- Operating temperature range: -20°F to +250°F with NBR material
- General-purpose LUP (lip-up) profile suitable for standard shaft alignment conditions
