6″ Flat Screw-On Filter Assembly
P # 127-380 & 127-380-B

This 6″ Screw-On Series Filters (Part #125’s, Part #126’s & P#127’s) were designed and recommend for tractor pulling and other motor sports ran on dirt. This 380 Micron Screen is for Extreme Diesel Engines and Six Cylinder Diesel Tractor Pullers. Its also for the user who wants to filter microscopic and dust particles out of a fluid or oil system that flows high volumes of fluid. Oil flows through the See Through Filter which is equipped with a coarse micron element which traps all the larger particles that can be viewed and inspected while the microscopic particles flow into and get filtered out by the System 1 or Disposable Filter screwed onto the bottom. The filtered oil then flows out of the filter assembly through the outlet opening. This dual stage filter will extend the life and flow of the disposable filter and still allow visual inspection of filtered particles without draining or leaking any fluid, unbolting or loosening any fasteners or fittings and with out any loss of oil. Seeing these filtered particles will help determine if they are from normal use or from bearings and other components excessively wearing in the engine or machinery supplying the Filter Assembly.

These 6” Screw-On Filters were designed to use a System 1 or a disposable filter on the bottom. Filters have a flat sealing surface on the bottom so a System 1 O-Ring seal can seal correctly. Early finned style System 1 filters which use 2 O-Rings can only use the outside O-Ring to seal. The inside one cannot be used. Recommend using the Billet Pro Series System 1 which uses a single larger O-Ring seal.
