Constructed from lightweight aluminum with a natural finish, the PERMA-COOL 184 adapter is designed for reliable performance in automotive, racing, performance, and custom cooling applications.

For best results, verify engine filter thread compatibility, available mounting clearance, gasket seating, and hose or fitting requirements before installation. The 3/8 in NPT female ports accept compatible fittings for configuring the oil cooler circuit. Proper sealing practices and installation procedures should be followed to help prevent leaks and ensure dependable oil flow.
