The Muncie 12T42738 is a Viton O-Ring used in Muncie PTO service and repair. Viton material is a fluoroelastomer compound known for resistance to petroleum-based fluids and heat, making it the correct choice for PTO sealing applications. This part appears in Muncie's own service parts documentation as item 27 for the relevant PTO assembly. Using the correct O-ring material matters: substituting a standard rubber seal where a Viton seal is called out can lead to premature failure. Pro Gear and Transmission carries this genuine Muncie component. Call us to confirm it is the right seal for your specific PTO unit.
