Description:
Dust Plugs & Caps keep the mating surfaces clean and free of contamination. They protect the critical mating elements of the couplings halves when they are disconnected. Nipples are protected from damage that would make the total coupling unusable.

General Specifications:
When ordering the dust cap/plug, body size must correspond to that of the coupler or nipple.
