One common type of oil seal is the lip seal, which features a flexible lip that makes contact with the rotating shaft to create a tight seal. Lip seals are often used in automotive engines, gearboxes, and industrial pumps due to their effectiveness in preventing oil leaks. Another popular option is the mechanical seal, which uses a rotating element to maintain constant contact with the shaft, ensuring a reliable seal even at high speeds and pressures.

Durability is another hallmark of FRP bridge deck panels. Unlike traditional materials, which can suffer from rust, rot, and chemical degradation, FRP materials are impervious to many types of environmental wear. This makes them particularly suitable for infrastructure that must withstand challenging conditions, such as roadway exposure to de-icing salts, moisture, and freeze-thaw cycles. Consequently, the lifespan of a bridge featuring FRP deck panels can extend significantly beyond that of conventional materials, promoting long-term sustainability in infrastructure investments.
