Spin On Adapter 3/4-16 Thread

The PERMA-COOL Spin On Adapter 3/4-16 Thread is a bypass oil filter adapter designed for custom cooling systems and high-performance engine builds. This adapter serves as a critical interface between your engine block and remote-mounted spin-on filter housings, allowing flexibility in filter placement away from traditional engine bay constraints.

Built for enthusiasts upgrading cooling capacity or relocating filtration systems on modified powerplants, this adapter eliminates the need for restrictive factory configurations and opens up routing options for complex cooling setups. The 3/4-16 UNF thread pattern is the industry standard for bypass filter heads on many performance cooling systems, ensuring compatibility with PERMA-COOL filter housings and aftermarket cold-case setups.

Mechanics and builders working on LS swaps, fuel-injected restorations, or liquid-cooled engine conversions rely on this adapter when factory filter mounts no longer suit their layouts. Installation requires direct threading onto the bypass port of your engine, making it a practical choice for various applications.
