Product Highlights
356T6 aluminum Type DC dust cap designed to close and protect a compatible 5" male cam and groove adapter.
The female coupler-style cap uses cam arms and a nitrile rubber gasket to provide a secure protective closure.
Technical Specifications
Type DC Connection Configuration
The Type DC cap fits over a compatible 5" male cam and groove adapter and provides a removable protective closure when the connection is not in use.
The mating male adapter enters the dust cap, where the cap's cam arms engage the adapter and the nitrile rubber gasket provides the sealing surface.
5" Aluminum Type DC Dust Cap Design
The 500-DC-AL is designed to close a compatible 5" male cam and groove adapter when the connection is disconnected. The cap helps protect the open connection from dirt, debris, and other contaminants during storage or downtime.
The Type DC configuration incorporates cam arms that engage the mating adapter for convenient installation and removal. Confirm the adapter size and compatibility before placing the dust cap into service.
Dixon manufactures the 500-DC-AL from 356T6 aluminum for use as a protective cam and groove closure. The aluminum body should be inspected before installation for damage, deformation, or contamination.
Check the cam arms and mating adapter at the same time to verify that the components engage correctly. Damaged or excessively worn coupling components should be replaced before use.
The 500-DC-AL is supplied standard with a nitrile rubber gasket positioned inside the dust cap. Dixon also notes that other gasket types are available for applications requiring a different seal material.
Inspect the gasket for cuts, distortion, deterioration, or contamination before installing the cap. Gasket condition and material compatibility should be reviewed for the intended application.
Dixon states that no standard exists for 5" cam and groove fittings and that these fittings generally do not interchange with other manufacturers. Compatibility should therefore be confirmed before ordering or installation.
Dixon also specifies that dust caps and dust plugs are not intended for pressure applications. The 500-DC-AL should be used as a protective closure rather than as a pressure-retaining component.
Installation & Selection Considerations
Confirm the 5" nominal size.
Verify part number 500-DC-AL.
Confirm the mating male adapter.
Inspect the nitrile gasket.
Use only as a non-pressure closure.

Our product specialists can help review 5" cam and groove sizing, Dixon 500-DC-AL compatibility, mating adapter requirements, gasket selection, and your intended closure application before you order.
