For anyone working on hydraulic systems on tractors, machinery, or equipment. This is a pack of 10 unbranded, aftermarket hydraulic hose fittings. They are 3/4\ size, with a Female JIC 37-degree flare swivel end on one side (that's the part that connects to another JIC fitting or port) and a 12-12 thread on the other side (which is the thread that gets crimped onto a hydraulic hose). The \12-12\ refers to the thread size for the hose stem. They're made to the common Parker style/interchange. These are brand new, perfect for making up new hoses or repairing old ones. Always double-check your thread sizes and sealing type (JIC vs. ORB, etc.) before ordering. Having a pack of common fittings like this on hand in the shop can save a lot of downtime. A basic, essential component for hydraulic repair and maintenance.
