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.

Product Overview

1.Wide Compatibility   Fit standard round aviation connectors with three common aperture sizes, two mounting options to match most panel installation demands.

2.Reliable Dust & Splash Proof   Elastic rubber fits tightly against connector opening, stop dust, moisture and debris from entering to avoid pin rust and unstable connection.

3.Integrated Anti-lost Strap   One-piece connecting tether keeps the cap attached to the equipment, no easy loss during repeated plugging and unplugging.

4.Durable Rubber Material   Aging-resistant, wear-resistant and flexible rubber material, stable performance for indoor and outdoor industrial equipment.

5.Standard Connector Accessory    Universal spare part for circular power & signal connectors, ideal for automation, new energy and wiring harness supporting use.
