5600 Series Industrial Interchange Quick Disconnect, Male Half, -10 Coupling, 1/2-14 Female Pipe

Application-wise, this type of quick disconnect sees action on agricultural equipment, construction equipment, and even in-plant manufacturing. It's also found on dump trucks, snow plows, and maintenance vehicles. So, it could be a good fit for your tractor, depending on what you're hooking up.

For a 1/2-14 female NPT connection, yeah, this one lines right up. The male half on this coupling carries a 1/2-14 NPT female thread on the pipe end, so it'll mate with a standard male NPT fitting on your line. It's rated for hydraulic fluid transfer and explicitly listed for dump vehicles, so that application fits squarely in its wheelhouse. Just confirm your existing socket half is compatible with the ISO 7241/1 Series A dimensional standard, since that's what this coupling conforms to.
