The Muncie 12T64073 is a Viton O-Ring sealing the PTO end in Muncie EX Drive shaft extension assemblies. Identified in Muncie's own service-parts documentation (SP18-04 Titan EX Drive) as the "O-Ring (PTO end)," this seal is a genuine Muncie service part. Viton material offers resistance to petroleum-based fluids and elevated operating temperatures, making it appropriate for PTO and hydraulic pump interface applications. The EX Drive is designed for Allison 3000 and 4000 series transmissions, and this O-Ring services the PTO-end of that assembly.
