This newly designed light-duty air/hydraulic riveter is ergonomically designed with the professional in mind. The MP-3V includes a Vacuum System and is designed to maximize stroke and pull force with a 3 jaw setup. Each tool is supplied with nosepieces to set 3/32″ – 3/16″ rivets in all alloys. Includes adjustment service wrenches, fluid applicator, spare jays and a removable swivel air connection line with air off/on valve built in. The adjustable Vacuum System control is located inside the mandrel collection bottle and allows you control the force of the air needed to hold the rivet in place. (or you may operate with the vacuum system turned off) Recommended air pressure is 85-95 PSI.
