The Peterson inline one-way pop-off valve protects engines by preventing ingested air when crankcase vacuum seals leak. It opens at about 2 psi to relieve pressure and uses -16AN male fittings for plumbing to an oil tank or catch can. Compact and service-friendly, this valve helps maintain proper crankcase vacuum and supports reliable operation in scavenged or catch-can oil systems.
