Value Brand

Value Brand 1-1/2 in Dust Plug Coupling

SKU CH-7PFA-4GGEJ

Aluminium dust plug with 1-1/2 in male adapter rated to 250 psi at 70 F

  • Seals 1-1/2 in couplings against dust and debris
  • Male DP-type adapter fits matching female fittings
  • Aluminium body resists corrosion in harsh environments
  • Rated to 250 psi at 70 °F for reliable pressure hold
  • Compact 2 5/16 in overall length saves installation space

1-1/2 in Dust Plug Coupling

This aluminum dust plug protects a 1-1/2 inch male adapter from contamination when the line is disconnected. It fits Type DP couplings and is rated for a maximum working pressure of 250 psi at 70 F. The plug is designed for use in hydraulic or pneumatic systems requiring a secure seal.

Replaces lost or damaged caps on 1-1/2 in adapters

Use this plug when the original dust cover is missing or the locking arm has failed. The jump is worth it whenever an open port risks fluid loss, dirt ingress or safety hazards during maintenance. It restores the sealing integrity of the coupling without replacing the entire fitting.

Withstands 250 psi continuously at 70 F

The aluminum body maintains its pressure rating under sustained system load rather than only during brief pressure spikes. Dimensions remain stable with a plug outside diameter of 2 7/64 in and an overall length of 2 5/16 in. High speed steel construction supports repeated installation and removal cycles without thread deformation.

Questions about this item

What clearance does the 2 7/64 in plug outside diameter need to fit?

The plug measures 2 7/64 in outside diameter, so allow at least that much clear bore space for insertion.

How do you seat the 1-1/2 in male adapter without cross-threading the 1 41/64 in plug length?

Start the male adapter by hand, turning clockwise until the threads engage fully, then tighten with a wrench; forcing it before the threads catch is the common mistake.

When should the aluminum body be inspected or replaced given the 250 psi rating at 70 F?

Check the aluminum body for corrosion, deformation or thread wear at each system service interval; replace it if any damage appears or after a pressure event exceeds 250 psi.
