Mechanical devices used in static or dynamic applications to separate two liquids or gasses or prevent the ingress of contamination.
Accordion bellows and protective boots are convoluted, expandable, fabric or elastomer components used to protect screws, shafts, slide ways and other components from liquid, chips, dirt and other debris.
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.
Bearing isolators are dynamic seals designed to protect bearings from outside contaminants. They are comprised of a rotor (rotating) and stator (stationary) member.
Bonded seals are metal washers with a rubber insert bonded to the inside diameter for use in high pressure applications.
Brush seals are used as a barrier against flying debris and liquid. They are also used to reduce or block the infiltration of light or air flow.
Grips, caps and closures are protective devices for the ends of a shaft, tube, pipe, fitting, connector, screw, bar, or other shape. They can also be used to provide a hand grip or hanger tip.
Compression packing seals or gland seals are deformable materials used to prevent or control the leakage of fluid between surfaces that move in relation to each other.
Conical and telescopic screw covers are used to protect ball, acme and lead screws from contaminants.
Diaphragm seals are isolation devices that separate a pressure instrument from the process media.
Diaphragms are flexible sealing element components that are used in pump, valve, and diaphragm seal applications. They provide a barrier between two chambers.
Die cutting services use a variety of die cutting methods to fashion materials into predefined shapes or sizes.
Dynamic seals include oil seals, hydraulic and pneumatic seals, exclusion seals, labyrinth seals, bearing isolators, and piston rings. They create a barrier between moving and stationary surfaces in applications such as rotating shafts and pistons rings. This is a general search form; more detailed search forms are available.
Edge trim and trims seals are used to provide a decorative or protective edge, or seal or fill a gap between two surfaces.
Electrical connector bases and covers are designed to provide mechanical protection for electrical connectors. They are available in many shapes and sizes to accommodate different types of electrical connections.
Exclusion seals are comprised of wipers, scrapers and V-ring seals.
Filler caps and fuel caps seal filling ports in tanks and reservoirs holding liquids or granular media. Filler caps and fuel caps prevent the ingress of foreign materials into and the leakage of fuel or media from the reservoir.
Flange protectors are designed to protect flanges from damage during shipping, or from exposure to corrosive elements.
Expansion joints connect two fixed assemblies or pipes and provide allowance for movement due to service load, shock, or thermal cycles.
Gaskets are used to prevent fluid or gas leaks by providing a barrier between two mating surfaces.
Hermetic seals provide a vacuum or leak tight seal such as a brazed glass-to-metal seal.
Hydraulic seals and pneumatic seals include piston seals, rod seals, U-cups, vee, cup, and flange packings.
Inflatable seals are elastomeric tubes designed to round out with the introduction of a medium (usually air) to form an tight barrier between a mounting and striking surface.
Labyrinth seals and clearance seals are minimum-leakage seals that protect machine elements from contamination through a noncontact method. They operate on the principle of positive clearance and do not rub on shafts or housing.
Machine way wipers provide a seal between a machine slide or way and a stationary surface.
Mechanical seals including mechanical face seals, bellows, gas seals, and cartridge seals.
Metal bellows perform a number of tasks including sealing environments, carrying gases, liquids and slurry, and mechanically coupling for electrical contact.
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.
Oil seals and grease seals have a flexible lip that rubs against a shaft or housing to prevent the leakage or ingress of fluids and dirt.
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.
Packer elements are down-hole sealing elements used to isolate sections in oil and gas drilling applications.
Piston rings are used for sealing cylinders. They can work at higher temperatures than elastomeric, fabric, or polymer seals.
Plugs, stoppers and inserts fit into holes or cavities and are designed for the ends of shafts, tubes, pipes, fittings, connectors, screws, bars, or other shapes.
Sealing glands are fittings that allow tubes, process pipes, cable or any single element assembly to be sealed in pressure / vacuum applications by use of a compression seal.
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.
Switch sealing boots protect switches from contaminants such as dirt, dust, gas, and liquids. They are generally tough, pliable silicone rubber devices for toggle, pushbutton, rocker, and rotary switches.
V-ring seals are all-rubber seals used primarily to exclude dirt and other contaminants. They are stretched over shafts and seal against the side of housing or another machine component.
Waterstops are static seals used between joints in concrete structures to prevent the passage of water or other fluids.
Way covers and way shields are machine tool accessories used to protect the rail or way of a machine from contamination and abrasive cuttings. Way covers come in two common styles: bellows type and telescoping type.
Weatherstripping is used to seal openings in doors, windows and other applications from water and other elements.
