Detroit DD13 DD15 Oil Pickup Tube O Ring A4721870880

The Detroit Diesel A4721870880 is a genuine OEM rectangular sealing ring (D-ring) used at the oil pickup tube connection on DD13 and DD15 engines.                                                                                                                     Made from Viton rubber rated at 75 durometer, this seal withstands the high temperatures and oil exposure inside the crankcase to maintain a leak-free connection between the oil pickup tube and the oil pump assembly. Two seals are required per engine during oil pump service.
