Cummins Radiator Elbow Hose #20987
- Heat and ozone resistant cover.
- Re-engineered materials resist vacuum collapse, this reduces the need for internal springs in many applications.
- Meets SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications.
- Engineered to resist electrochemical degradation - the leading cause of hose failure.
- Recommended for upper, lower, bypass, heater and other coolant hose applications.
Gates recommends replacing standard worm drive and spring loaded clamps with Gates PowerGrip® SB Clamps each time a new coolant hose is installed.
