1. Leak Prevention One of the primary functions of a hub oil seal is to prevent oil leaks. If the oil seal fails, the lubricant can escape, leading to insufficient lubrication of the bearings and other critical components. This can result in increased wear and tear, decreased performance, and eventually, catastrophic failure.

The design of PU oil seals also plays a significant role in their functionality
pu oil seal. They often feature a-like structure that creates a tight seal against the mating surface, preventing the leakage of oil or other fluids. This design, combined with the elastic memory of polyurethane, allows the seal to recover its original shape after compression, maintaining a consistent seal even under fluctuating pressures.

2. Durability Cast iron itself is a durable material known for its high tensile strength. When combined with hot galvanization, the longevity of elbows is significantly increased, reducing the need for frequent replacements and maintenance. This durability makes brass fittings more cost-effective in the long run.
