How does the O-ring work on a cap?
The O-ring uses the system pressure to increase the sealing force acting on the cap. The cap also prevents extrusion of the O-ring energizer when used in high pressure applications. The plastic cap is typically made from a low friction material, such as PTFE.
What does an O-ring seal look like?
Whether it is small or large diameter, low or high pressure, reciprocating or rotary motion, dynamic or static sealing, a suitable product for your application is available. An O-ring is a solid-rubber seal shaped like a dough nut or torus. When compressed between mating surfaces, an O-ring blocks the passage of liquids or gases.
How is a plastic cap used to seal a seal?
A plastic cap provides a seal against the dynamic sealing face, an O-ring is used to energize the plastic cap and operates in a static environment. The O-ring uses the system pressure to increase the sealing force acting on the cap. The cap also prevents extrusion of the O-ring energizer when used in high pressure applications.
When to use sealed caps and glyd rings?
Designed to be used in reciprocating hydraulic, pneumatic and dry applications at pressures up to 3,000 psi where o-rings and x-rings do not perform well enough on their own. Can be more cost effective than more complicated custom seals.
What kind of seal is an O ring?
An O-Ring is a solid-rubber seal shaped like a dough nut or torus. When compressed between mating surfaces, an O-Ring blocks the passage of liquids or gases. O-Rings are available in a wide range of standard and non-standard sizes that are suitable for nearly all sealing applications.

What’s the standard size for an O ring?
The standard sizes used by major O-ring manufacturers are defined by Aerospace Standard AS568A, Aerospace Size Standard for O-rings. That document, published by the Society of Automotive Engineers (SAE), lists the sizes of O-rings in six series or groups in both inches and millimeters.
