DC cam-latched self-locking dust cap fits A/E/F male quick connect fittings, stainless steel one-piece casting with dual spring handles, 3s tool-free lock & unlock. Dustproof, leak-proof, corrosion resistant for tanker & chemical pipeline, meets MIL-C-27487 & A-A-59326 standards.






This product is a DC-type cam-latched self-locking cover, also referred to in the industry as a quick-connect plug cover, dustproof
block cover, or male-end protection cap. It is designed for use with Type A/E/F male quick-connect fittings and
achieves rapid self-locking sealing through dual-side spring handles, enabling easy installation and removal without tools. It
serves as a standard protective component for oil tankers, chemical fluid transportation systems, and oil loading/unloading
pipelines.
Core Functions:
1. Dust protection: Idle pipelines and public connector ports are sealed to prevent dust, rainwater, and sediment from entering
the pipes, avoiding medium contamination;
2. Leak-proof sealing: Built-in rubber gaskets seal pipe openings during storage, transportation, and static periods to prevent
residual liquid leakage;
3. Rapid self-locking mechanism: Dual-sided pull-ring cam handles lock automatically upon engagement; simply lift the ring
for quick unlocking, with assembly/disassembly completed in 3 seconds;
4. Corrosion-resistant durability: Cast from stainless steel in a single piece, suitable for corrosive environments such as
chemical industries, oil systems, and seawater;
5. Universal interchangeability compliant with international standards MIL-C-27487 and A-A-59326, ensuring compatibility
with rapid connectors of identical specifications worldwide.
