Question by: Troy B on Jul 25, 2025, 9:18 PM

Does the 0306-14 use a JIC 37 degree flare fitting, and what tube size does that thread work with?

Answer by: Customer Support on Jul 27, 2025, 8:25 AM

Male JIC SAE 37 degree flare is correct, and the thread is sized for a 7/8 inch tube OD. The thread itself is 1 3/16-12, and it meets SAE J514 spec. Pretty standard JIC setup for hydraulic line work.
