O-Ring Kit for Oil Filter Adapters

The O-Ring Kit for Oil Filter Adapters (Barnes ORK-109) is an essential maintenance component designed for users running aftermarket oil filter adapter systems on their engines. Oil filter adapters are commonly installed on performance vehicles, off-road builds, and custom engine configurations to improve filtration flexibility and remote filter mounting capabilities. Over time, the o-rings and copper washers in these adapters degrade due to heat cycling, oil exposure, and pressure fluctuations, compromising the seal integrity and risking oil leaks or bypass conditions that can damage engine bearings and components.

This kit includes replacement o-rings and copper washers manufactured to OEM specifications for Barnes oil filter adapters, ensuring a factory-correct seal without modification or re-engineering. The rubber o-ring material is selected for chemical resistance to engine oils, synthetic blends, and coolant contact, while the included copper washers provide reliable metal-to-metal sealing surfaces that prevent pinhole leaks at high operating pressures. The compact kit weighs just 0.01 lbs and fits easily in any toolbox, making it an efficient solution for preventive maintenance or emergency field repairs on the trail or at the track.

Technicians, engine builders, and DIY enthusiasts benefit most from stocking this kit, particularly those who service multiple vehicles or maintain equipment in remote locations where OEM parts availability is limited. Installation requires only basic hand tools and takes minutes—simply remove the adapter housing, replace the degraded seals with new o-rings and washers from the kit, and reinstall. Compatibility is universal across Barnes oil filter adapter platforms, making this a go-to solution for anyone running remote-mounted filtration systems on street vehicles, off-road trucks, marine engines, or motorsport applications.
