The Muncie 4B237 is a 3-inch split flange O-ring designed for Muncie power takeoff applications. Split flange connections rely on a correctly sized O-ring to maintain a hydraulic seal at the flange face, and the 4B237 is the Muncie-specified part for 3-inch split flange configurations. Sourcing the correct O-ring by part number matters: an undersized or oversized ring will not seat properly and can cause fluid loss at the connection. Pro Gear and Transmission carries genuine Muncie parts. Not sure this is the right O-ring for your setup? Give us a call before ordering.
