Rod Seals

 The rod step seal is composed of a PTFE rod seal ring and an O-ring. The PTFE filled sliding ring has low friction characteristics and can be used in applications with poor lubrication.
The Rod step seal is especially suitable for control cylinders, servo systems, machine tools, construction machines, and chemical industry applications.
Different PTFE material sliding rings and rubber material O rings can be selected for different applications to meet different fluid media and temperature ranges.

Product Overview
The Double Acting Rod Seal, also known as a dual action rod seal, is engineered to deliver bidirectional sealing performance in hydraulic and pneumatic cylinders. It ensures tight sealing during both the extension and retraction strokes, making it an ideal solution for double acting cylinder applications that demand consistent pressure control and zero leakage.    
Whether used in high-pressure hydraulic systems or fast-moving pneumatic equipment, this double-lip rod seal provides reliable and durable sealing under dynamic conditions. 

This heavy-duty hydraulic rod seal is engineered for high-performance sealing in large-diameter, high-pressure environments. Featuring a PTFE-filled sealing element and a profiled energizer, it ensures reliable performance in systems with wide extrusion gaps, short strokes, and oscillating motion (dithering).
Its ultra-low friction and anti-extrusion properties make it ideal for critical hydraulic applications such as rolling mills, injection molding machines, and hydraulic presses.

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.
