Calibration Pumps
The Magnum Pro Calibration Pumps use dual O-ring on all pistons and a synthetic non-disbursing lubrication on all moving parts. Unlike other calibration pumps the Magnum Pro does not use a needle valve which in most cases is the primary cause of failure. Instead it uses the “virtually” indestructible Schrader valve.
