Inline Straight Rotary Coupling
A single-passage inline rotating joint designed for hydraulic lines that require continuous or intermittent rotation. Compact and straight-through in configuration, these couplings allow one end to rotate freely relative to the other — ideal for preventing hose twist and torsional stress in rotating equipment. Available in BSPP port sizes from ¼" to 2".
