Description
5" Aluminum Type DP Dust Plug
5" Aluminum Type DP Dust Plug provides a protective closure for compatible 5" female cam and groove couplers when the connection is not in use.
Constructed from 356T6 aluminum, the Dixon 500-DP-AL is designed to help keep dirt, debris, and other contaminants out of an open cam and groove connection. Dixon specifies that dust caps and dust plugs are not intended for pressure applications.
Product Highlights
356T6 aluminum Type DP dust plug designed to provide a protective closure for compatible 5" female cam and groove couplers.
The male plug configuration engages the mating coupler and helps protect an open connection when equipment is disconnected.
Technical Specifications
Type DP Connection Configuration
The male plug inserts into a compatible 5" female cam and groove coupler to close the open connection when it is not being used.
The mating female coupler uses its cam arms to engage and retain the Type DP plug as a removable protective closure.
5" Aluminum Type DP Dust Plug Design
The 500-DP-AL is designed to close a compatible 5" female cam and groove coupler when the connection is disconnected. The plug helps protect the open coupling from dirt, debris, and other contaminants during storage or downtime.
The Type DP configuration provides a removable closure without adding another threaded connection. The mating coupler's cam arms secure around the plug during installation.
Dixon manufactures the 500-DP-AL from 356T6 aluminum. The metal construction provides a durable protective component for compatible Dixon cam and groove coupling assemblies.
Inspect the plug before installation for damage, contamination, or excessive wear. The mating coupler should also be checked so the plug can seat and engage correctly.
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.
Verify that the mating 5" female coupler is appropriate for the Dixon 500-DP-AL. Do not assume that nominal size alone guarantees proper fit between different manufacturers.
Dixon specifies that dust caps and dust plugs are not to be used in pressure applications for safety and environmental reasons. The 500-DP-AL should be treated as a protective closure rather than a pressure-retaining component.
Confirm that the system is safely isolated before installing or removing the dust plug. Use a properly rated component whenever the application requires pressure containment.
Installation & Selection Considerations
Confirm the 5" nominal size.
Verify part number 500-DP-AL.
Confirm the mating female coupler.
Inspect the plug before installation.
Use only as a non-pressure closure.

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