Air Cleaner Smog Adapter

The SPECIALTY PRODUCTS COMPANY Air Cleaner Smog Adapter (Part Number 7290) is a precision-engineered PCV fitting designed for small-block and big-block marine engine applications. This essential component is crucial for proper crankcase ventilation system routing in both inboard and outboard powerboat installations.

Constructed from natural aluminum, this PCV adapter provides reliable directional control for crankcase gases while maintaining the sealed ventilation pathway that modern marine engines require. The 90-degree elbow design accommodates tight engine compartment layouts, and the 3/4-inch hose barb ensures a secure, leak-free connection to standard marine PCV hose.

This adapter is ideal for boaters performing routine engine service, restoration work, or upgrading cooling and ventilation systems on older or high-performance engines. Weekend fishermen maintaining aging patrol boats and serious offshore anglers performing mid-season engine maintenance both rely on quality PCV components to prevent pressure buildup and extend engine longevity.
