Mercedes OM604 OM605 OM606 Sealing Ring and Pre-Filter Set Fuel Lines FKM

This high-quality maintenance kit with FKM (fluororubber) O-rings allows for sealing the original fuel lines, as well as replacing and sealing the diesel pre-filter on your Mercedes OM604, OM605, and OM606 engine. After many years of operation, the original O-rings become hard and brittle, which can allow air to enter the lines, leading to poor starting behavior and power loss under high loads.

Comparison numbers: A6019970345, A6019970445, A0219977548, A6010920105, A6019970148.

Can generally also be used for: OM601, OM602, and OM603.

Many O-rings on the market for this purpose are made of NBR, which is inferior to FKM in terms of resistance and heat stability. In addition, the pre-filter never comes with the right O-ring, which is extremely annoying.
