O-rings provide reliable leak-free seals and simple installation. O-rings are an ideal, cost-effective solution for many sealing situations. An O-ring is a donut-shaped ring of molded, flexible material with a round cross-section that can be either solid or hollow. These flexible rings are designed to be inserted into a groove (referred to as a gland) where they predictably “de-form” themselves to completely fill the gap in the cavity, creating a perfect seal. Elegantly simple in function, the classic O-ring is the most popular choice for engineers as an ideal, cost-effective solution for a myriad of sealing challenges. Best used as a static seal, O-rings provide reliable, leak-free seals with ease of installation.

Another type of static seal highly useful in a wide range of environments is a gasket. These flat mechanical seals are commonly used to prevent leakage between two flanges while under compression. Advantages Ability to withstand high compressive loads (2000 psi or higher) Nearly unlimited range of materials Unlimited variety of standard and custom shapes to fit any application Web Seal offers gaskets in: Sizes from 0.25 inch to 10 feet Low-volume to high-volume runs Many applications lend themselves to a custom cut shape that accomplish precise sealing, packaging or placement needed by your component or equipment.

Dynamic seals are more complex sealing devices that provide high performance in an endless variety of seal geometries. Three-dimensional like the O-ring, dynamic seals are engineered with superior tolerances to provide tight closures involving moving parts. Dynamic seals are ideal for: Oscillating motion Reciprocal motion Rotating motion Pneumatic seal Seat seal Vacuum seal Web Seal offers a variety of dynamic seal types to accommodate normal to extreme environments: Back-up rings Bearing isolators EMIRFI seals Excluder seals U-cups V-cups Wipers Mechanical seals Oil seals Piston seals Polypaks Radial seal shafts Spring-loaded seals Thrust washers

Grommets can be either single-piece or two-pieced, and are typically hand-inserted. Grommets usually serve to: strengthen and protect openings insulate and protect objects passing through openings , where a vulnerable material such as wire could be cut or abraded relieve strain, as with power supply cords, to prevent stressing the connections
