Ring made from flexible material that fits into a groove and, when compressed, creates an oil seal.

(r) see seal, 0-ring.

O-ring An O-ring is an elastic material in the shape of an ‘o', used as a seal. The cross-section of the ‘o' may also be circular, but occasionally another shape (e. g.,‘x' in ‘quad rings')

A rubber or polymer donut shaped seal. Used heavily in hydraulics and pneumatics to seal high pressure vessels and cylinders.

A type of sealing ring usually of rubber or similar flexible material, that is compressed into grooves to provide the sealing action.

a circular cross-section ring molded

a doughnut shaped (annular) rubber or plastic ring which is placed in a groove and compressed to seal fluid or gas from passing a particular point

a doughnut-shaped, circular seal (view A of fig

a doughnut shaped object, generally made from an elastomer, although some plastics (urethane, teflon) are sometimes used

a flexible loop of material, often rubber, which is seated between two components during assembly and compressed between them

a loop of elastomer with an O-shaped cross section that is used as a seal

a round ring that is used as a gasket for sealing a connection

a rubber or vinyl band that is compressed between the two sections when you latch them together

a rubber washer that holds things together

a skinny doughnut-shaped piece of rubber or neoprene that fits in a square slot

a small circular shaped contraption, typically manufactured from a variety of rubber or plastic

a torus, or doughnut

A circular disc of rubber which fits snugly around the piston to help maintain a seal between piston and cartridge wall.

A type of seal consisting of an elastomer in the shape of a doughnut. O-rings are usually mounted in a groove for sealant purposes.

An elastomeric or synthetic seal ring of circular cross section.

Round rubber washer used to create a watertight seal, chiefly around valve stems

A small rubber ring that provides a water seal in faucets and other plumbing fittings.

a rubber ring used on retainers and beadless jewelry such as plugs or fleshtunnels, to hold the jewelry in place by surrounding it (with one on each side of the jewelry) so that it cannot fall out.

Round rubber washer or gasket that is compressed to create a watertight seal, typically in a compression fitting.

An elastomer gasket enabling a moisture seal, having a circular cross section. See Rubber.

functions as a seal through the mechanical deformation of the elastomeric compound by mating metal surfaces. This creates a condition of zero clearance which blocks the liquid or gas being sealed. The pressure which causes the O-Ring to move is supplied by mechanical pressure or squeeze generated by proper gland design, material selection, and by the system pressure transmitted by the fluid itself.

Thin rubber gasket used to create a waterproof seal in certain plumbing joints or between two parts of a device, such as between the lid and the strainer pot on a pump.

A rubber seal used around stems of some valves to prevent water from leaking by it.

A circular piece of rubber which fits around the piston to help maintain the seal between the piston and cartridge wall.

a circular seal common in the oilfield; requires deformation (squeeze) to energize and seal.

Used as a gasket to seal the flashlight case against dust and moisture.

A rubber ring designed to make solid temporary joins water-tight.

Is a round gasket that is used as a vacuum seal.

A ring of pliable material, as rubber or neoprene, used as a gasket.

A round ring having a square or round cross section used as a seal, such as at the end of a hydraulic line.

A circular gasket generally made of natural or synthetic rubber compound, that is used for sealing applications to prevent entry and/or leaking of fluids, air, moisture, dust, etc.

O-rings are used to seal the backs of watches, which feature either a press-in back or a screw on back. They ensure water resistance . Usually also used on the winding stems of watches and in the winding crowns to protect against the ingestion of water and dust. Normally made from a rubber/plastic compound.

Used to seal watch mechanisms to ensure water resistance.

A round elastomeric gasket with a round cross section that seals a joint against a pressurized fluid such as water.

A thin, rubber ring that fits snugly on the end of a plug to keep it in place in your piercing.

A packing or sealing device shaped like an "O", which is compressed between two mating surfaces to prevent the escape of anything it is sealing.

A doughnut-shaped object, or torus, that functions as a seal, blocking the passage of liquids or gases, by being compressed between the two mating surfaces comprising the walls of the cavity (gland) into which the ring is installed.

An O-ring is a loop of elastomer with a round (o-shaped) cross-section used as a mechanical seal or gasket. They are designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
