Syn-Tech NS-3913-G1 is a highly specialized, breakdown-resistant synthetic lubrication compound engineered specifically for high-stress aerospace applications. Formulated with advanced extreme pressure (EP) and anti-wear additives alongside robust rust inhibitors, it delivers superior film strength under extreme mechanical loads.
It stands as the only lubricant formally approved by Bell Helicopter Textron for use on their critical Crown Gear Driveshaft couplings.
It prevents dynamic metal-to-metal wear, resists breakdown across a wide temperature range, and is supplied in a resealable 6 oz tube for precise maintenance dosing.
