Featuring a 1-16 UN thread size, it effectively removes contaminants from engine oil, with efficiency ratings of Beta 2 at 10 micron, Beta 20 at 21 micron, and Beta 75 at 25 micron. This filter includes both an anti-drainback valve and a bypass valve set at 172 kPa (25 PSI), ensuring consistent oil flow and preventing dry starts. It is a direct equivalent to John Deere part numbers like RE504836 and is compatible with a wide range of John Deere tractors, combines, sprayers, and forage harvesters.
