An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.

O-rings are highly versatile and widely used as a sealing solution due to their efficiency, affordability, and ease of use in both static and dynamic applications. They are crafted from a wide range of elastomer materials, capable of sealing practically any liquid or gas.

2023年8月14日 · An O-ring is a type of rubber sealing ring that has a circular cross-section. It gets its name from its O-shaped cross-section, and is commonly referred to as an O-ring. The O-ring was first introduced in the mid-19th century as a sealing element for steam engine cylinders.

2024年2月5日 · O-rings, also known as rubber rings or toric joints, are ring-shaped seals possessing a circular cross-section to resemble their namesake letter O. They’re primarily made of a rubber elastomeric material and provide an affordable and reliable means of sealing hydraulic, pneumatic, and related machinery components.

An O-ring is a circular elastic seal used in both static and dynamic applications. Its primary function is to create a seal between structures such as pipes, tubes, pistons, and cylinders. Made from various materials to suit different applications, O-rings are highly flexible.

2025年1月16日 · An O-ring is a mechanical gasket with a round cross section. The name O-ring comes from the fact that the item is shaped like the letter O and looks like a ring. An O-ring is a closed loop circular band that.

2015年10月20日 · How does an O-Ring seal? Seals prevent fluids from escaping through the gaps in mating pieces of hardware. The O-Ring sits in the middle of a gland when it’s at rest, but as pressure begins to rise in the sealing system, the O …

2023年4月30日 · An o-ring is a circular mechanical gasket used to create a leak-free seal between two components. The o-ring sits in a groove and gets compressed during assembly between two or more parts, creating a reliable seal at the interface.

2019年1月29日 · Also known as a toric joint — in reference to its torus shape — an O-ring is a gasket with a circular-looped design that’s used to seal two working surfaces. The valve stems in automotive engines, for example, often use O-rings to prevent oil …

2024年5月14日 · O-rings are round seals with a cross-section shaped like a circle made of rubber or silicon. They are used to prevent gases and liquids from flowing through machines and equipment. Such rings fit in the groove and then squeeze between two parts, tightly sealing them.
