The hub axle seal's primary function is to keep the axle lubricated. The lubricant, often a type of grease or oil, is crucial for reducing friction between moving parts. Without proper lubrication, the components can suffer from overheating and excessive wear, potentially leading to significant damage and costly repairs. Additionally, the seal prevents water and dirt from entering the axle assembly, which can cause rust and corrosion, further jeopardizing the integrity of the axle.


One of the main functions of starter shingles is to prevent water infiltration. The eaves of a roof are particularly vulnerable to moisture, especially during heavy rains or snowmelt. By installing starter shingles, you provide an additional layer of protection at the onset of your roofing system. These shingles are usually designed with a wider design and a sealant strip that helps bond them to the substrate. This strong connection prevents water from seeping beneath the shingles and causing leaks or other water damage.
