Cast Aluminum PCV Air Cleaner Smog Fitting

• Cast aluminum PCV/breather fitting for smog-legal air-cleaner service

• Natural finish for a clean, durable engine-bay appearance

• 90° inlet angle, fits 3/4" PCV/breather hose

Mounting hardware included for straightforward installation

This cast aluminum PCV/breather vent fitting is built for air-cleaner assemblies needing a smog-legal PCV or breather connection point. It is a vent fitting, not a filter element — it manages crankcase ventilation routing rather than filtering intake air.

The fitting uses a 90° inlet angle and fits 3/4" PCV/breather hose; confirm this diameter matches your hose before ordering. Cast aluminum construction with a natural finish supports long-term engine-bay durability and appearance. Mounting hardware is included.

Applications
Used for PCV/breather system service on air-cleaner assemblies; suited to custom intake-system builds needing a smog-legal vent fitting.

Sizing
90° inlet angle, 3/4" inlet diameter, cast aluminum, natural finish.

Is this a filter or a vent fitting?
This is a PCV/breather vent fitting, not an air filter. It provides a connection point for crankcase ventilation hoses on an air cleaner assembly.

What hose size does this fitting fit?
This fitting is designed for 3/4-inch PCV/breather hose.

Does this fitting come with a gasket?
This listing specifies that mounting hardware is included, but it does not specifically list a gasket. Confirm with TSP whether a gasket is included before ordering.

What's the difference between this and the ABS plastic version?
This version is made from cast aluminum with a satin finish, while the other version is made from ABS plastic. Both are 90-degree, 3/4-inch PCV/breather fittings, with the primary differences being the material and finish.
