HP Series Protective Dust Caps and Plugs

Protective Dust Caps and Plugs play a crucial role in the performance of quick couplings.  They help to keep the mating surfaces clean and free of contamination.  Dust Caps and Plugs also protect the critical mating surfaces of the coupling halves when they are disconnected. 

  • Dust Plugs are used on couplers (female half of coupling). 
  • Dust Caps are used on nipples (male half of coupling).
