Bumped, bruised, beaten up and knocked around. Your tools take a lot of abuse. That’s why hilmor has retooled manifolds and gauges to handle any climate. The hilmor 4-valve Aluminum Manifold is built to last with a forged aluminum body. It’s designed to be leak-resistant with replaceable stainless steel valve seats, SAE-style O-rings and a securely seated large sight glass. Need faster vacuum pulls? It has you covered with a true 3/8" bore throughout the valve. Front-mounted hose positions and a permanent location for temperature clamps result in added convenience. And it’s finished off with comfort-grip rubberized handles optimally sized for easy turns. Set sold with our hilmor Dual Readout Thermometer and 60" refrigeration hoses with ball valve adapters.
