Weatherhead T-402 Air/Hydraulic Pump

The Weatherhead T-402 Air/Hydraulic Pump is a pneumatic-powered hydraulic unit designed to deliver up to 4,200 psi of hydraulic pressure when used with Eaton/Weatherhead Coll-O-Crimp systems. This model is often used to power hose crimping presses (such as T-400 series) in industrial and mobile environments, delivering clean, oil-pressurized force from shop air (60–120 psi). Its compact, durable design includes a reservoir, filter, and internal valving to support reliable crimp operations.
