got a -06 quick disconnect setup, is this dust plug the right size for it?
Answer by: Customer Support on Feb 2, 2026, 3:19 PM

Question by: Brenda W on Aug 20, 2025, 7:12 AM
what seal materials come standard on this dust plug? trying to make sure it'll hold up with what we're running through the lines.
Answer by: Customer Support on Aug 21, 2025, 8:35 PM
Buna-N, EPR, and Viton are all included as standard seal options for the 5600 Series. That gives you some flexibility depending on your fluid type, since those three cover a pretty wide range of common hydraulic and industrial media. The body itself is zinc plated steel with zinc poppet guides, so it's built to handle regular shop and field conditions without much fuss.

Will this dust plug fit a standard 3/8" quick disconnect?
Answer by: Customer Support on Jan 4, 2026, 9:39 PM
It's made to fit couplings with a -06 size, which corresponds to a 3/8 inch end size. It also conforms dimensionally to ISO standard 7241/1 Series A, meaning it should be compatible with other industry-standard equipment.
