End Cap Seals are used to seal off open-end bores and protect internal components from external contaminants. These seals are designed to provide static sealing in applications where rotating shafts are not present but closure and protection are still required. The compact construction and reliable fit make them suitable for a range of industrial uses.
1. Product Features
· Sealing Function: Provides axial sealing against fluids, dust, and environmental exposure
· Design Structure: Typically includes a rubber-elastomer body with a metal reinforcement for structural rigidity
· Press Fit Installation: Designed to be press-fit into housing bores for secure positioning without additional fasteners
· Optional Vent or Drain Designs: Available for applications requiring pressure balancing
2. Material Availability
· Nitrile (NBR): For mineral oil-based fluids and standard temperatures
· Fluoroelastomer (FKM): For higher chemical resistance and elevated thermal ranges
· EPDM / HNBR: Options for specific environmental or fluid compatibility
3. Typical Applications
· Gearbox housings
· Motor end covers
· Axle and differential assemblies
· Hydraulic systems
· Static bore closures in pumps and compressors
4. Benefits
· Simplifies housing design by eliminating the need for additional sealing elements
· Helps prevent dirt, water, or grease ingress into non-rotating cavities
· Reduces assembly time with interference fit sealing
· Can be supplied with custom dimensions to meet specific equipment requirements
End Cap Seals are often used as protective closures and NQKSF are available in a variety of standard diameters. Material selection and dimension customization can be supported upon request.
