Material flexing and mechanical flexing are the two basic types of coupling. The flexibility of the material flexible kinds is obtained by stretching or compressing a resilient material, such as rubber, or by flexing tiny metallic discs or grids. With the exception of grid couplings, material flexing couplings do not require lubrication.

A door seal, also known as an edge strip, is a rubber or plastic channel with various shaped profiles. They’re perfect for keeping drafts at bay. Door seals and edging strips are used to protect the margins of panels, doors, and windows from exposed sharp metal or glass edges. When applied around doors and windows, sealing strips and edging also work as draught excluders and help keep heat in. When cables and wires are carried through frames or grids in electrical systems, edging strips protect the outside insulation from damage.

A gasket fills the gap between two or more mating surfaces to provide a mechanical seal. Its purpose is to prevent leakage from or into the linked objects while they are being compressed. Gaskets enable machine parts to have less-than-perfect mating surfaces. They can fill imperfections and improve sealability, particularly in high-pressure applications and flanges with a wide temperature differential range (cyclic flanges).

A rubber stopper is a small, tapered plug that is used to close the openings of test tubes, flasks, and other laboratory glassware. For this purpose, cork stoppers are also available. Rubber stoppers, on the other hand, are preferred for applications requiring a tighter seal or greater chemical resistance.

Gaskets are typically made from a flat material, such as paper, rubber, silicone, metal, cork, felt, neoprene, nitrile rubber, fiberglass, polytetrafluoroethylene (PTFE or Teflon), or a plastic polymer (such as polychlorotrifluoroethylene).

O-Rings (sometimes referred to as packing joints) are donut-shaped gaskets that can be employed in both static and dynamic applications. O-Rings are one of the most often used seals in machinery because they are simple to make, affordable, and dependable.

Rubber rollers take advantage of elastomer qualities such impact strength, shock absorption, compression and deflection, abrasion and chemical resistance, high coefficient of friction, and variable hardness.

Door gaskets are used to seal gaps around the edges of doors (the jambs and the header). You can significantly reduce the infiltration of sound, light, draught, moisture, fire, and smoke by sealing the gaps along the door frame. Using a door gasket to create a more insulated environment is a reasonably easy and cost-effective solution.

Rubber roller with rib is made up of an annular section or ring with one or more axially projecting circumferential ribs on one side and one or more axially projecting circumferential grooves on the other.

Rubber bumpers, sometimes known as grommet bumpers, are small pieces of rubber material used to protect machines, equipment, and other objects from harm. They usually have a circular shape with a little hole in the center, however this isn’t always the case.
