The R006 Series U-Cup is a popular and versatile design with a wide range of applications. The design features a primary sealing material that is further energized by an elastomeric element, frequently an O-Ring. This allows a high sealing force to be created at the sealing lips or allows the use of seal materials that might otherwise have insufficient compression set resistance. This versatility allows this seal to be used across many markets. Manufactured in a variety of materials and sizes from 6 mm up to 1600 mm in standard or custom diameters.

Cantilever Spring Seals make use of a V shaped spring embedded in a polymer jacket. At installation, the V shape of the spring is compressed, providing sealing energy to the seal jacket ensuring a positive seal.  They are common replacements when rubber u-cups fail due to chemical attack, extreme temperature range, friction concerns and wear issues. Cantilever Spring Seals are best suited for reciprocating applications such as shocks, hydraulic cylinders, pumps and compressors. The shape of the spring concentrates load on the front of the seal, which makes this design also suitable for use as environmental excluders and for applications requiring scraping of viscous media. As an additional option, the spring cavity area can be filled with silicone for FDA clean-in-place applications.

The R007 Series is a heavy-duty polyurethane seal with multiple features that include a double-lipped U-Cup design, an internal O-ring energizer and a reinforced backup ring on the heel. This seal is ideal for pressure spikes and large extrusion gaps common in mining applications.

Helical Spring Seals are comprised of a wound ribbon metal spring installed in a polymer jacket. This helical shape spring affords a relatively high load versus deflection range resulting in a seal product that can provide very tight sealing. As a highly loaded product, Helical Spring Seals should be considered when dynamics are very slow or static. Examples are in stems seals and in cryogenic valves where additional force is required to overcome thermal effects.

The P001 Series standard-duty piston seal is a low-friction design, consisting of a PTFE-filled seal and an O-ring energizer. It is designed for double-acting cylinders in challenging applications, where low friction and high wear resistance are needed.

Canted Coil Spring Seals employ a specialty wound wire spring installed in a polymer jacket. The canted coil is unique in the sealing industry because of its semi-linear load curve. As an engineered loading device, canted coil springs display a very constant load over a large deflection range. This feature allows Canted Coil Spring Seals to operate in friction sensitive applications like HPLC, encoders and flap actuators with consistent performance. Seals used in battery operated devices utilize these seals – minimizing seal friction and optimizing battery life. On the other end of the spectrum, Canted Coil Spring Seals are used with heavy load springs for use in highly viscous media such as epoxies and urethanes. 

The P002 Series Single-Acting Piston Seal is a low-friction design, consisting of a PTFE filled seal and an O-ring energizer. It is designed for single-acting cylinders in challenging applications, where low friction and high wear resistance are needed.

Flanged seals are a special class of radial seals with an added feature to help retain the seal under rotary forces. The flange is an extension of the heel of the seal, which locates in a counterbore of the housing. At assembly, the seal flange gets pinched in the housing providing a positive mechanical lock that keeps the seal stationary. Flanged seals are an excellent choice for equipment that can be designed with end plates. In these cases, assembly of a flanged seal is simple and provides a robust design as well as a level of redundant sealing on the static side of the gland. Process machinery that require a product to be contained (mixers, augers, spool valves) are good applications of this design.
