Next, apply a small amount of grease to the seal lip(s) and the area of the shaft in contact with the seal. When using a double-lip seal, fill the small cavity between the two lips with grease as well. This both protects the lips during initial installation and break-in, and also acts as another barrier keeping contaminants out. When installing rubber-coated seals, apply lubricant to the outside diameter as well. This will help prevent the seal from rebounding or backing out from its mounting place.

- In the intricate machinery of modern industry, the humble NBR oil seal stands as an unsung hero, ensuring the smooth operation of countless components. NBR, or nitrile butadiene rubber, is a synthetic rubber widely used for its exceptional resistance to oil, fuel, and other fluids commonly found in industrial settings. The integration of NBR material into oil seals has revolutionized the way we maintain lubrication and prevent leakage in mechanical systems.
- In conclusion, E3 spark plugs are a superior choice for drivers who want to get the most out of their vehicle. With their advanced technology, innovative design, and proven performance, E3 spark plugs are a wise investment for anyone looking to enhance their driving experience.

In recent research, MWCNTs and carbon black were mixed with the butadiene/natural rubber to form a hybrid composite which gives very strong filler links by partial replacement of carbon black based on the m1:m2:X (m1—MWCNT; m2—reduction amount of carbon black; X-varies from 1 to 6) [40,64]. An internal blending mixer and two-roll milling were used to formulate the composites. The synergistic effect plays a major role in improving the abrasion resistance property due to the partial replacement of carbon black by adding MWCNTs in different ratios. The optimal ratio value of MWCNTs is 5 (parts per hundred of rubber) and 27.5 (parts per hundred of rubber) for carbon black with better resistant to abrasion compared to the matrix material [64]. The vulcanized hybrid composite material reinforced with MWCNT/carbon black at the ratio of 1:1 shows better mechanical properties, curing characteristics, and thermal conductivity. This shows a better tyre thread with an improved endurance life, less curing time, and improved thermal conductivity [42,64]. Fig. 4.4 shows the SEM and TEM images of uncured and cured rubber and Figs. 4.5 and 4.6 show the application of rubber nanocomposites in a tyre application.

PTFE Oil Seals - A relatively new and exciting oil seal, the use of polytetrafluoroethylene means that they can withstand dry or unlubricated operations. With a massive thermal range of -130ºC to +200ºC and a strong resistance to chemicals, they are considered to be the future of rotary shaft seals.
