The Moroso 3/8in NPT vacuum relief valve is a single billet-aluminum valve designed to provide vacuum relief in oiling or crankcase systems. Its 3/8in NPT thread allows straightforward installation into compatible ports, and the billet construction offers durability for repeated use. The valve gives a simple mechanical method to limit vacuum where an NPT-mounted relief is preferred.
