Seals

Polytetrafluoroethylene (PTFE) is commonly used in the construction of seals. Many O-rings, for instance, are entirely of PTFE. You can place them around the mating surfaces to prevent leaks. Even when exposed to pressurized fluid or gas, they will continue … Read More

You can’t choose the right O-ring without considering the size. O-rings are mechanical seals that feature a circular, ring-like shape. They are typically used to seal mating surfaces. Even when exposed to pressurized liquid or gas, O-rings will continue to … Read More

Nitrile is commonly used in the construction of seals, including O-rings. Nitrile O-rings are ring-shaped seals. They are made of nitrile, which is an elastomer that’s able to expand and contract in response to temperature changes. It’s essentially a  copolymer … Read More

Rubber extrusion is a common manufacturing process. It involves the use of an extrusion machine to create rubber products. In addition to electrical connectors and grommets, rubber extrusion is used to make seals. Here’s everything you need to know about … Read More

Seals are an important part of many machines. They are commonly used around fluid- and gas-carrying hoses. As the fluid or gas inside of a hose heats up, it will expand. This thermal expansion can cause the fluid or gas … Read More

Not all seals are the same. In addition to standard O-rings, there are spring-energized seals. Spring-energized seals feature the same ring-shaped design as their O-ring counterparts, but they are comprised of two parts: a jacket and spring. Spring-energized seals work … Read More

O-rings and lip rings are two of the most common types of mechanical seals for machinery. Machinery often features pressurized liquid or gas. The mating surfaces for pressurized liquid or gas may feature an O-ring or lip ring. The O-ring … Read More
