Sierra 223-7804 Oil Filter, Replaces Onan 185-7444 and Fischer Panda 15853-99170

The Sierra 223-7804 is a marine generator oil filter engineered as a direct replacement for select Onan and Fischer Panda generator sets. Built from stainless steel for durability in the harsh marine environment, this filter is designed to meet or exceed the performance of the original equipment part it replaces. It threads onto the generator's oil filter housing using an M16 x 1.5 thread size, and its compact 3 x 3 x 3.5 inch profile fits within the tight engine compartments typical of marine generator installations.

This filter is intended for routine oil filter maintenance on Fischer Panda PMS 12 DP, PMS 12 MINI, PMS 4200, PMS 6500, PMS 8 DP, and PMS 8 MINI generators, as well as Onan MDKAU and MDKBH generator models. It cross-references directly to Onan part number 185-7444 and Fischer Panda part number 15853-99170, so it can be used as a straightforward equivalent during scheduled service intervals. As a Sierra product, it is backed by Sierra's customer satisfaction warranty covering defects in workmanship and materials for the useful life of the product.
