Aluminum Lockable Cam-Lock Dust Cap – Industrial Fluid Protection Solution
The aluminum lockable Cam-Lock dust cap is a premium protective accessory designed to safeguard Cam-Lock couplings and hose ends from dust, dirt, and unauthorized access. Widely recognized across the globe, this type of dust cap is often referred to as a “Lockable Camlock Dust Plug”, “Dual-Handle Locking Cap”, or “Secure Cam-Lock End Cap”. It is commonly used in fuel transfer systems, industrial chemical pipelines, agricultural liquid systems, and food & beverage liquid transfer operations, providing a reliable sealing and security solution for fluid systems.
Material and Structural Features
This series is crafted from high-strength aluminum alloy for durability, corrosion resistance, and lightweight handling. The handles are made of brass and divided into two segments, with the top section of each handle featuring a lock hole. When the two top handles are folded together, the lock holes align perfectly, allowing a padlock to secure the cap in place. This feature effectively prevents unauthorized operation or accidental disconnection.
The dust cap uses a Buna-N (Nitrile) gasket to ensure reliable sealing. Custom gaskets, including FPM/FKM (Fluororubber), are available for higher temperature or corrosive applications. The working pressure is 0.6 MPa, making it suitable for most industrial liquid systems.
Applications
The aluminum lockable dust cap is ideal for:
Fuel transfer protection: Gas stations, fuel trucks, and storage tanks
Industrial chemical pipelines: Protects unused or temporary hose ends from contamination
Agricultural liquid systems: Secures fertilizer or pesticide transfer lines
Food and beverage liquid systems: Keep connections clean and prevent unauthorized access
Temporary or mobile piping setups: Easy to attach and lock for transport or storage
By securing Cam-Lock couplings with a lockable dust cap, operators can prevent dust contamination, reduce leakage risk, and ensure safety in multi-user environments.
Common Sizes
ALLDC-250: 2.5″ Lockable Dust Cap
