RUBBER SEALS are used to create a barrier between a rotating and a stationary surface. They function to retain or separate lubricants or fluids, keep out contamination, and contain pressure. V-Ring seals are all rubber seals used primarily to exclude dirt and other contaminants. Wipers are also flexible lip exclusion seals. Hydraulic seals and pneumatic seals are designed for the reciprocating motion that is common in hydraulic and pneumatic applications, such as cylinders. Rod seals & Piston seals are radial seals. The seal is fitted onto a shaft with the sealing lip contacting the housing bore. Double acting or bi-directional seals are effective when sealing in both directions.

Rubber WASHERS are disks of rubber placed beneath a nut, an axle bearing, or a joint, to relieve friction, prevents leakage, isolate, prevent loosening or distribute pressure. There are many different types of washers and washer-type products for a variety of applications. Common types include Flat Washers, Beveled, C-Washers, D-shaped Washers, Sealing Washers, Spherical Washers, Square Washers & Shoulder Washers. Flat Washers are thin, flat, and circular general-purpose washers, with a centrally located hole.

Rubber O-Rings are a loop of elastomer with a round cross-section intended to be seated in a groove and squeezed together during assembling between two or more parts creating a seal at the interface to block the passage of liquids or gases. O-Rings selection is based on chemical compatibility, service temperature, sealing pressure, lubrication requirements, and working atmosphere. O-rings can form a static or dynamic seal. A static seal is where the O-ring does not move and is used simply for containing pressure or maintaining a vacuum. Dynamic seals can be reciprocating (like a piston and cylinder), or rotating (shaft rotating in a housing). Axial squeeze and radial squeeze are two methods for applying an O-ring.
