94k Short Block Intensifier as used on our 94k pumps. Completely interchangeable with Flow 87/94k intensifiers - but upgraded! - hydraulic piston (3 bands for better stability; - improved/interchangeable check valve outlet design (designed for better water flow); and - better production processes used on check valve bodies and hp cylinders for much longer life. The shift sensor mounting threads are #10-24. Usually several are in stock and ready to ship. Rebuild service of old intensifiers is also available with quick turnaround.
