Hydraulic Oil Service Plugs, 2 Large, 2 Medium, 4 Small

Mess Stopper Hydraulic Oil Service Plugs are most commonly used to prevent oil leaks when servicing equipment and machinery. The plugs also keep your equipment and oil clean during servicing. Their gradual taper allows them to fit a variety of hole sizes, eliminating the need to keep and store the right size plugs and caps. Mess Stopper is made of oil-resistant, silicone-free NBR rubber. It is resistant to most oils and chemicals such as conventional and synthetic lubricating and hydraulic oils, transmission fluids, pure gasoline, diesel fuel, ethylene glycol coolants, and water. It has short-term resistance to ethanol-blended fuel and brake fluids. To ensure compatibility, always test the Mess Stopper for fluid resistance by immersing it in the fluid and observing for degradation.
