OTC 4004 2-Speed Hydraulic Hand Pump

The OTC 4004 2-Speed Hydraulic Hand Pump is a rugged all-metal manual pump designed for professional mechanics, collision repair shops, and general hydraulic applications requiring portable, reliable power for single-acting rams. Two-speed operation delivers high-volume low-pressure flow (.305 cu. in./stroke first stage) for rapid ram approach, switching to high-pressure (.076–.091 cu. in./stroke second stage) up to 10,000 PSI. With a 24.4 cu. in. reservoir (approx. 20 cu. in. usable), 3/8" NPT oil port, and maximum handle effort of just 90 lbs., it's an economical choice for tasks needing quick setup without electricity or air. Durable construction ensures long-term performance in demanding shop environments.
