Ball Bearing and Nut Kit for Polaris Hose – Compatible with 280/3900 – 3 x D20 + 6 x D15

This precision bearing kit maintains the rotary joints of the hoses on Polaris 280, 3900, and other pressure washer models. Smooth hose rotation is essential for proper pressure washer operation and thorough tank cleaning.

The kit includes two bearing sizes: D20 and D15, to be installed at various connection points on the hose. Over time, these bearings can rust or wear, which can lead to stiffness, twisting, or even cracking of the hose.

Regularly replacing these small but vital bearings ensures optimal hose rotation, prevents damage caused by torque buildup, and extends the life of the entire system.
