Cap Seal
The Cap Seal is the original slipper seal developed in the mid-1950s’s to improve the performance of O-Rings and Back-up Rings used in older versions of the MIL-G-5514 gland standard. The Cap Seal was originally designed to provide a cost-effective cap seal solution that prevents extrusion and eliminates O-ring spiral failure in dynamic applications. Each seal is a dual-acting seal that combines a cap made from Armorlene®, CDI’s PTFE material, and an Arylast™ elastomeric energizer which demonstrates excellent friction and sealing properties. The Cap Seal provides non-stick-slip starting and excellent dry running.
Features and Benefits
- Lower friction and elimination of spiral failure, which leads to better system performance.
- Surrounds the O-ring, protecting it from extrusion when under pressure.
- Hardware (gland diameter) can be modified to improve seal friction without affecting leakage control.
- Utilizes standard aerospace grade O-Rings.
- Configuration includes a cap component with circumferential grooves (for better dynamic sealing and lubrication retention) and notches (reference SAE AIR1243 for blow-by protection)
- Note that some sizes of the Cap Seal do not include grooves or radial notches
- Alternate configurations are available upon request, including Seal Caps component without circumferential grooves and/or notches.
- Designed for use in MIL-G-5514 and AS4716 glands.
