Frequently Asked Questions

Seals are devices used to prevent or control the escape of fluids or gases from a system. They are typically used in mechanical equipment such as pumps, valves, and cylinders.

O-rings are a type of seal that is shaped like a torus, or donut. They are used to seal the space between two parts and prevent the escape of fluids or gases. O-rings work by creating a tight seal between two surfaces through compression.

U-cups are a type of seal that are shaped like a U. They are used in hydraulic systems to prevent fluid from escaping between a piston and a cylinder wall. U-cups work by creating a tight seal that prevents fluid from passing through the space between the piston and the cylinder.

Vee Packings are a type of seal that are used in hydraulic and pneumatic systems. They are made up of a series of rings that are stacked together to form a tight seal. Vee Packings work by creating a tight seal between two surfaces through compression.

When selecting a seal, factors such as operating temperature, pressure, fluid compatibility, and seal material should be considered.
