Hydraulic Seals

Glass filled POM wear ring, offers high bearing load capacity over a broad range of temperatures. The function of the wear ring is to guide the piston and piston rod of a hydraulic cylinder, as well as to withstand arising side loads. At the same time, it prevents any metal-to-metal contact, which will damage and score the surfaces and eventually cause seal damage, leakage and component damage.

This wear ring is capable of withstanding high side loads and preventing metal-to-metal contact between the piston and the bore or the rod and the gland.

The PTFE back-up rings are proven components used for sealing both low and high pressure systems. Any system pushing the pressure limits on an elastomer seal, back-up rings are an inexpensive option to increase seal pressure capabilities or increase radial extrusion gaps behind the seal.
The back-up rings come standard in Virgin PTFE but can be made from any filled PTFE compound to increase the pressure capabilities.

PEEK,POM, Nylon back up ring are also made.

Spring energized seals are typically used in areas where elastomeric seals cannot meet the frictional, temperature, pressure, or chemical-resistance requirements of the application, XHH designs and manufactures a full line of spring energized seals for your application.

The R001 Series rod seal is a low-friction design, consisting of a PTFE-filled seal and an O-ring energizer. The sealing lip design is optimized to ensure maximum sealing performance at both low and high pressures. The lip design features a “pump-back” capability, which eliminates pressure trapping when used as a buffer seal in a Zero-Leak Technology configuration.

The R004 Series U-Cup seal is one of XHH Seals’ most popular designs used in standard-duty applications. Its asymmetrical design ensures that the seal lip forces are optimized for every cross section and diameter. When used within a sealing system, the R004 is a key component of XHH Seals’ Zero Leak Technology. Manufactured in a variety of materials and sizes from 6 mm up to 1600 mm in standard or custom diameters.

The R005 Series U-cup seal is a high-performance, double-lipped seal for use as a primary seal, typically in moderate to high-pressure applications. Its asymmetrical design ensures that the seal lip forces are optimized for every cross section and diameter. When used within a sealing system, the R005 plays a key component of XHH Seals’ Zero Leak Technology. Manufactured in a variety of materials and sizes from 6 mm up to 1600 mm in standard or custom diameters.

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.
