(163 companies)
Feedthroughs transmit electrical current, fluids, optical signals, or mechanical motion through the walls of a pressurized or vacuum system through a hermetic seal.

Cable Glands

(269 companies)
Cable glands are bulkhead modules that allow barrier penetration while providing sealing protection. They are commonly known as sealing glands or strain reliefs and have the ability to seal around one or multiple wires, cables or probes. They are available in plastic and metal configurations.

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.

Metal Ring Seals

(85 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.
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.

Dynamic Seals

(677 companies)
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.

Case Equipment

(317 companies)
Case equipment is machinery used to form, pack, seal, or unpack cases of products.
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.
Hydraulic seals and pneumatic seals include piston seals, rod seals, U-cups, vee, cup, and flange packings.

Exclusion Seals

(136 companies)
Exclusion seals are comprised of wipers, scrapers and V-ring seals.

Diaphragm Seals

(108 companies)
Diaphragm seals are isolation devices that separate a pressure instrument from the process media.

Inflatable Seals

(30 companies)
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.

Mechanical Seals

(350 companies)
Mechanical seals including mechanical face seals, bellows, gas seals, and cartridge seals.

Laboratory Stoppers

(66 companies)
Laboratory stoppers are truncated, cylindrical or conical pieces that are used to plug, close and/or seal labware.
Waveguide pressure windows are used to seal waveguides at high pressure and prevent contaminants from entering the system.
