Gasket vs. Bushing — What's the Difference?

A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Given the potential cost and safety implications of faulty or leaking gaskets, it is critical that the correct gasket material is selected to fit the needs of the application.

A fixed or removable cylindrical metal lining used to constrain, guide, or reduce friction.

Any of a wide variety of seals or packings used between matched machine parts or around pipe joints to prevent the escape of a gas or fluid.

(Electricity) An insulating lining for an aperture through which a conductor passes.

(Nautical) A cord or canvas strap used to secure a furled sail to a yard, boom, or gaff.

An adapter threaded to permit joining of pipes with different diameters.

(sailing) A length of rope or canvas band used for reefing a sail, or holding a stowed sail in place.

(mechanical engineering) A type of bearing, a cylindrical lining designed to reduce friction and wear inside a hole, often used as a casing for a shaft, pin or hinge.

(mechanics) Any mechanical seal that serves to fill the space between two objects, generally to prevent leakage between the two objects while under compression.

(mechanical engineering) An elastic bearing used as a type of vibration isolator, commonly made of rubber. An interface between two parts, damping the movement and the energy transmitted.

A material which may be clamped between faces and acts as a static seal. Gaskets may be cut, formed, or molded to the desired configuration.

(mechanical engineering) A threaded bushing: a fastener element that is inserted into an object, usually to add a threaded hole in a softer or thin material.

Any of a wide variety of seals or packings used between matched machine parts or around pipe joints to prevent the escape of a gas or fluid.

(electrical engineering) A lining for an opening through which a conductor passes, providing insulation and mechanical protection for the conductor.

To fit a gasket

An adapter for joining pipes of different size.

Present participle of bush

A line or band used to lash a furled sail securely. Sea gaskets are common lines; harbor gaskets are plaited and decorated lines or bands. Called also casket.

The operation of fitting bushes, or linings, into holes or places where wear is to be received, or friction diminished, as pivot holes, etc.

The plaited hemp used for packing a piston, as of the steam engine and its pumps.

A bush or lining; - sometimes called a thimble. See 4th Bush.

Seal consisting of a ring for packing pistons or sealing a pipe joint

An insulating liner in an opening through which conductors pass

A cylindrical metal lining used to reduce friction
