The Meritor 31313-29M (also listed as 3131329M) is a genuine Meritor thru tee O-ring designed for trailer axle service. O-rings at the thru tee position seal the connection point where a line or shaft passes through a tee-type fitting in the axle assembly, preventing lubricant loss or contamination ingress at that junction. Sourced directly through Meritor's parts network, this is a genuine Meritor component sold by Pro Gear and Transmission. If you need to verify this is the correct O-ring for your specific axle configuration, give us a call before ordering.
