Mercedes All Models 397 Pc. Metric O-Ring Assortment in Case

This must-have kit does not only have hard-to-find metric sizing, but the o-rings are made out of nitrile which holds up better to heat and is more resistant to oil, grease, hydraulic fluid, silicone and even water. Kit contains 30 different common METRIC sizes ranging from 2.8 mm ID to 47.7 mm ID.

Just being able to use one or two of these o rings in an emergency to solve a leak or prevent a trip to the hardware store will pay for the kit.  Just think of having 382!!!
