This hydraulic assembly is a 2 wire, working pressure 6,000 PSI. 1/4" hose x 72" with 2 female JIC swivels #4 with thread size 7/16 x 20. Please check your old assembly to confirm threads sizes. If you used a 9/16 WRENCH SIZE ON THE FEMALE SWIVEL NUT this assembly will work. If you used any other size wrench please let me know and I help you find the correct assembly, or I build you one that will work. All of our assemblies have plastic caps over each fitting to protect the threads during shipping or in storage. If you have any questions please let me know. We only offer free shipping to the 48 contiguous states. We do not ship free to Puerto Rico, Alaska or Hawaii.
