Metal Ring Seals

(84 companies)
Metal ring seals are static devices that can withstand high operating temperatures, pressures, and vacuums. They can also withstand cryogenic conditions and high face-to-face cycling.
Form, fill and seal machines are packaging equipment that uses flexible, heat-sealable, plastic film to form packages that can be filled with a product and then sealed, and cut.
Sealers and seal coatings are used to seal surfaces or to form a barrier on a surface. They differ from sealants, which are used to seal joints or gaps between surfaces.

Seal Repair Services

(36 companies)
Seal repair services refurbish and repair seals and related seal components.
Edge trim and trims seals are used to provide a decorative or protective edge, or seal or fill a gap between two surfaces.

Bearing Isolators

(52 companies)
Bearing isolators are dynamic seals designed to protect bearings from outside contaminants. They are comprised of a rotor (rotating) and stator (stationary) member.

Machine Way Wipers

(48 companies)
Machine way wipers provide a seal between a machine slide or way and a stationary surface.

O-rings

(766 companies)
O-rings are solid-rubber seals that are shaped like a doughnut. When pressed between two mating surfaces, O-rings block the passage of liquids or gases.
Hermetic seals provide a vacuum or leak tight seal such as a brazed glass-to-metal seal.

Solid Elastomeric Rings

(111 companies)
Solid elastomeric rings are compression seals of differing cross sections. Some examples are X or multiple rings, rectangular rings, tetraseals, trapezoid rings, T-section rings, delta rings, D-rings, H-rings, heart rings, and diamond rings.

Piston Rings

(109 companies)
Piston rings are used for sealing cylinders. They can work at higher temperatures than elastomeric, fabric, or polymer seals.

Weatherstripping

(85 companies)
Weatherstripping is used to seal openings in doors, windows and other applications from water and other elements.

Diaphragms

(74 companies)
Diaphragms are flexible sealing element components that are used in pump, valve, and diaphragm seal applications. They provide a barrier between two chambers.

Waterstops

(15 companies)
Waterstops are static seals used between joints in concrete structures to prevent the passage of water or other fluids.

Back-up Rings

(120 companies)
Back-up rings or anti-extrusion rings are washer-like devices used to prevent seals from extruding through gaps while under pressure. Seals are installed in the downstream side of the gland.
