Question by: Rhonda B on Mar 15, 2026, 8:56 AM
Can this coupling handle the high pressure in my hydraulic system, or do I need somethin' beefier?
Answer by: Customer Support on Mar 16, 2026, 2:26 PM
Dura-Kote plating and brass construction mean this coupling can handle operating pressures above standard SAE thresholds, exceeding the minimums set by SAE.
