Among the many parts that make up an exhaust system, the seal ring is a pretty cheap and easy to replace component. It is important to replace it when a car's exhaust system needs to be cleaned or replaced. The ring may be made from a variety of materials, such as copper, aluminum or stainless steel, and come in two sizes. The ring may have a relatively small diameter, compared to the diameter of the cylinders. However, it should have good high temperature resistance.

The ring consists of a number of metal wires, many of which are of sufficient diameter and hardness to stand up to the wear and tear of an engine. The ring is woven in a three-strand configuration with each wire being 0.009 inches in diameter. In fact, this ring is one of the cheapest gaskets on the market. The ring may be made from AISI 309 or 316 stainless steel. The ring may be coated with Teflon, graphite, or mica.

The ring may be used in conjunction with other exhaust related components, such as an exhaust manifold or a catalytic converter. It is the most cost-effective way to ensure proper exhaust sealing. A good seal is the best way to protect your engine's components. A good ring will not only ensure proper exhaust sealing, but also keep your engine free of rust, abrasion and corrosion.

A ring with the best performance is a composite made from 85% stainless steel, 15% mica and a small amount of Teflon or graphite. The ring may be coated in a variety of ways, including the coating of the ring's actual wires.
