Additionally, modular handrail systems are known for their safety features. They often meet or exceed local building codes and regulations, providing peace of mind to architects, builders, and occupants alike. The robust materials used in these systems, such as stainless steel, aluminum, and high-grade polymers, ensure longevity and resistance to wear and tear, enhancing the overall security of a structure.

The spring shown in the figure is known as a garter spring, and it maintains tension on the sealing lip of the seal. Garter springs are closed coil springs used in the form of a ring, the ends of which are connected together as shown in Figure 2.10.

Classical oil seals consist of a metal housing that carries the dynamic sealing lip and provides the static sealing function. These are usually manufactured of elastomer material, such as ACM, Silicone or FPM. Further, since they are in contact with the surface of the rotating shaft, the lip is pressed onto the shaft surface by means of a spring ring.

The care taken during the installation process will pay off by allowing the seal to work quietly and operate efficiently behind the scenes of your application.

Here are some additional tips that will help you have a successful O-ring installation.
Even though it’s better than other materials in terms of toughness and wear time, it is preferably used in dry-running applications. The salient demerit of this material is its cost.


The first step in installing oil seals is to clean the surface where they will be placed. Dirt, debris, and other contaminants can cause the oil seal to become damaged or misshapen, leading to leaks. Clean the surface with a solvent or soap and water, and make sure it is completely dry before installing the oil seal.
