Spin-On Oil Adapter 1in-16 Theads 1/2in NPT

The Spin-On Oil Adapter 1in-16 Threads 1/2in NPT from PERMA-COOL is an essential component for custom engine builds, remote oil filtration setups, and high-performance cooling systems. This adapter allows you to relocate your spin-on oil filter away from the engine block, a critical modification for tight engine compartments, custom intake manifolds, or when installing auxiliary cooling lines. Whether you're building a street rod, upgrading a fuel-injected engine, or installing an aftermarket oil cooler system, this threaded adapter provides the connection point your modification demands.

Engineered with precision machining, the Spin-On Oil Adapter features 1-inch-16 UNC male threads that mate directly to your engine block's filter boss, while the 1/2-inch NPT female port accepts standard hose fittings or remote filter mounting brackets. The compact 4.15 x 2.05 x 6.1-inch design minimizes clearance conflicts in congested engine bays, and at just 0.6 lbs, it adds negligible weight while maintaining structural integrity under pressure cycling. PERMA-COOL's reputation in cooling system engineering ensures this adapter is manufactured to tight tolerances, preventing oil weeping and ensuring consistent pressure delivery to remote filter housings or sandwich-style cooler blocks.

Mechanics and engine builders routinely specify this adapter when fabricating custom oil cooling setups for naturally aspirated and turbocharged engines alike. The 1/2-inch NPT port accepts readily available braided hose, block-mounted filter canisters, or oil temperature sandwich gauges, making it compatible with nearly every remote filtration scenario. Installation is straightforward—thread directly into your existing oil filter boss location and connect your auxiliary system to the NPT port. This adapter is indispensable for anyone serious about thermal management upgrades or space-constrained engine compartment modifications.
