3/8” NPT 5/8” UNF LH closed-seal union single passage for coolant or MQL. The closed seals are perfect for transfer line and similar applications. The union’s full-flow design has no obstructions to trap swarf or debris and is bearing-supported with a threaded rotor for easy installation. Deep groove radial ball bearings bring smooth operation, and a labyrinth system with large vents protects the ball bearings. Balanced mechanical seals made from silicon carbide are present for long life, even under difficult operating conditions. Lastly, anodized aluminum housing and a stainless steel rotor resist corrosion.
