1231 Series Hydraulic Straight Adapter JIC 37° Male x SAE O-Ring Male -Configure your measurements

The Dixon 1231 Series is the standard adapter for converting "straight thread" (SAE ORB) ports on modern machinery into a universal JIC outlet. This adapter uses the SAE ORB (O-Ring Boss) system on the machine-side. The seal is achieved by compressing the O-Ring against the port's chamfer, ensuring superior leak-tightness under vibration. The other end offers a Male JIC 37° cone, ready to receive any standard hydraulic hose.

Technical Advantages:

• Size Versatility (Jump Sizes): The table shows a wide variety of "Jump Sizes" (e.g., connecting a 1/4" hose to a 3/8" port). This allows hoses to be adapted to pumps without using multiple reducing bushings, thereby reducing leak points.

• Zero Leaks: Combines the security of the O-Ring in the port with the metal-to-metal JIC seal on the hose.

• Component Protection: Being straight thread, there is no risk of cracking the pump housing due to over-tightening (as occurs with NPT).

• Resistance: Zinc-plated carbon steel capable of withstanding 5,000 PSI, the standard for yellow and agricultural machinery.

Recommended Applications

• Pump Connection: Main pressure outlet in gear and piston pumps.

• Hydraulic Cylinders: Inlet and outlet ports in John Deere, CAT, etc. machinery cylinders.

• Hydraulic Filters: Adapting filter inlets that usually come with ORB thread.
