PAI 621208 Oil Pickup Tube O-Ring | Replaces Detroit Diesel A4721870880
The PAI 621208 Oil Pickup Tube O-Ring is a premium OEM-quality replacement sealing ring designed for Detroit Diesel DD13 and DD15 engines. Replacing OEM part number A4721870880, this Viton® rectangular sealing ring creates a leak-free seal between the oil pickup tube and oil pump, helping maintain proper oil pressure and protecting your engine from premature wear.
A damaged or hardened oil pickup tube seal can allow air to enter the oil pump suction side, leading to reduced oil pressure, oil pump cavitation, and accelerated engine wear. Replacing this inexpensive seal whenever the oil pump or lower end is serviced is recommended preventative maintenance during any engine repair or overhaul. The OEM-style seal is manufactured from high-temperature Viton (FKM) material for outstanding resistance to engine oil and heat. citeturn0search0turn0search8
