O-Ring Boss Radius An Port Adapters
Russell radius port adapter fittings are precision machined for positive thread engagement. They feature radius profiled angles at port inlet/ outlet for optimum flow. These adapters are ideal when connecting regulators and fuel lines to pumps and tanks, and are also useful for dry sump applications. A black anodized finish is applied for appearance and durability. Each fitting is packaged complete with o-ring seal, except for -10 (670670) and -12 (670680), 1/2" NPT, which requires thread sealant.

Russell seal: what to know
A worn seal lets oil seep out or get burned. Replacing it is cheap; getting to it is usually the work.
