The TurboWerx High-Flow In-line filter is a true in-line filter - both male and a female 3/8" NPT ports. It is the most compact all-metal in-line screen filter available, yet has a massive bore of .45” (same size as -10AN) for maximum flow, and is bi-directional. It features double o-ring sealing, and a 150µ stainless steel element that is easy to inspect/clean/replace. The body is aluminum with the anti-corrosion nickel-plating.
