Grunge Armor | 2-Pack | Dust Cap, Fits Male ISO/Pioneer Style Hydraulic Quick disconnects Like 8010-4, 6602-8-10, and Others. Yellow Molded Cap with Retention Ring Keeps Cap Attached to Hose

The ID of these MALE HYDRAULIC connector covers is ~15/16. It fits over the OD of a FEMALE air line quick connect fitting. It's nice and snug but easy enough to get on and off. Feels like it won't disintegrate soon like the throway caps that sometimes come on air fittings. My pics show examples on the bench, on the shop air manifold and on my van bumper OBA fitting.The tether and ring part of the thing is pretty big. ID of the keeper ring is about 1-1/16. So it's BIGGER than the fitting you're covering. Might be a little visually BIG in some applications. I don't think I'd want it hanging off the front of my bumper, at least in this bright yellow. But it seems simple to modify if you really wanted less tether on the thing. Plus it's available in several colors.Just be sure to get the ones made for MALE HYDRAULIC fittings. That's what these are. They will fit our FEMALE OBA and other QD air fittings.Thanks - Lumpy
