This assembly is a 3/4", 2 wire with a 3,000 working PSI. The over all length is 60 inches, with 2 female JIC swivels #12, threads are 1 1/16 x 12. PLEASE CHECK YOUR OLD ASSEMBLY; the wrench on each side that you used was 1-1/4 on the female swivel nut, this assembly will thread to your equipment. If you used any other size wrench please let me know, I will help you find the correct assembly that will work, if not we build you one. All of our assemblies come with plastic caps on the end of our fittings, this will help protect the threads during shipping or in storage.
