Adaptor - Straight (M X FS) JIC - UNO - SAE Specification

A Straight Adaptor (M x FS) JIC - UNO under SAE specifications is a hydraulic fitting that connects:

• JIC (Joint Industry Council): 37° flare fitting, typically conforming to SAE J514
• UNO (Unified National O-ring): Also known as SAE Straight Thread O-ring Boss (ORB), conforming to SAE J1926

JIC (SAE J514):

• Thread Type: 37° flare, straight thread
• Seal Type: Metal-to-metal seal via the 37° flare
• Common Sizes: 1/8" to 2"
• Material: Carbon steel, stainless steel, brass
• Applications: High-pressure hydraulic systems

UNO / ORB (SAE J1926):

• Thread Type: Straight thread with an O-ring
• Seal Type: Elastomeric O-ring compressed into a chamfered port
• Common Sizes: Matches UNF thread sizes (e.g., 7/16-20, 9/16-18)
• Applications: Leak-free connections in hydraulic systems, especially where vibration is present

Adaptor Configuration:

• Male JIC: 37° flare male thread
• Female Swivel UNO (ORB): Straight thread with internal O-ring groove, swivels for easy installation
• Straight Body: Inline connection

Applications:

• Hydraulic systems in mobile and industrial equipment
• Fuel and oil lines
• Agricultural and construction machinery
• Marine and aerospace systems

This type of adaptor is ideal when transitioning from a JIC hose or tube to a port or component with an ORB (UNO) thread.
