The Vevor PCP hand pump is a 4-stage high-pressure air pump designed for airguns, scuba tanks, paintball use, and general inflation tasks. It delivers up to 4500 PSI and includes a built-in oil-moisture filter to help provide cleaner, drier air. An easy-to-read pressure gauge with a 0-6000 PSI range helps support accurate filling. Its aluminum alloy pump tube, stainless steel construction, rubber handle, and foldable base are built for durability, portability, and stable operation.
