Premium Spin-On Adapter Kit (13/16-16in)

The DERALE Premium Spin-On Adapter Kit (13/16-16in) is a bypass-style oil filter adapter engineered for custom cooling system integration on high-performance and modified engines. This aluminum block-mount adapter accommodates 13/16-16 inch center thread applications and features dual 10 AN O-Ring ports for inlet and outlet circulation, enabling builders to route engine oil through auxiliary cooling systems without disrupting primary filtration. The black powder-coat finish provides corrosion resistance in demanding operating environments.

Constructed from aluminum with precision-machined ports, this adapter kit delivers reliable flow management under sustained operation. The 10 AN O-Ring inlet and outlet configuration ensures compatibility with standard hose and fitting ecosystems common in custom automotive and powersports builds. Bypass filtration allows unfiltered oil circulation during cold-start conditions while full-flow filtration remains intact, protecting bearing surfaces without excessive pressure drop. Weight of 0.87 lbs keeps installation mass minimal on engine blocks where every fraction of a pound matters for balance and cooling efficiency.

This adapter suits builders integrating auxiliary oil coolers, sandwich-style filters, or secondary filtration stages on engines where direct block mounting is preferred over inline plumbing. Technicians working on street performance vehicles, track-dedicated engines, or heavy-duty cooling upgrades rely on DERALE spin-on solutions to simplify plumbing and reduce complexity. The 13/16-16 in thread size matches common small-block and mid-size engine architectures, making it a versatile choice for retrofit cooling system projects where space and flow routing demand precision engineering.
