Key Specifications & Features
- Product Type: Straight ORFS Tube Union (Male × Male)
- Port Configuration: Male O-Ring Face Seal on both ends.
- Size Configuration: Dash size -06 x -06, which matches a 3/8-inch nominal tube or hose outer diameter (OD) for both connections.
- Thread Details: Both sides utilize standard straight 11/16-16 UN/UNF threads.
- Seal Mechanism: Each male side features a precision-machined flat face containing a groove with an elastomeric O-ring (typically 90 Durometer Buna-N). When mated against a female flat-face swivel nut, the O-ring compresses to create a leak-proof, zero-clearance seal optimized for high-vibration systems.
