Circular Connector Waterproof Dustproof Rubber Protective Cap

Circular Connector Waterproof Dustproof Rubber Protective Cap

This rubber protective cover is compatible with common circular power and signal aviation connectors. It offers two installation structures: single hole and 4-hole flange mounting. The attached lanyard prevents loss after opening, effectively blocking dust and splashing water to shield idle connector sockets from oxidation, corrosion and mechanical damage. It is a necessary supporting accessory for industrial circular connectors.
