50Hydraulic PU BS rod seal
BS seal is rod seal for hydraulic cylinders, single-acting, polyurethane u-cup design with secondary sealing lip, and fit closely at the outer diameter. The additional lubricant retained under the secondary lip seal largely prevents wear and dry running. It is critical in fluid power equipment, preventing leakage from within the cylinder.
Leakage from cylinder will damage the performance of the equipment and in extreme cases, may lead to environmental pollution problems. Therefore, it is very important to select the correct rod seal type and design to suit the specific application.
It is mainly designed for the sealing of piston rods and plungers in heavy duty applications in mobile and stationary hydraulics.

Advantages: 1. Unusually high wear resistance. 2. Insensibility against shock loads and pressure peaks. 3. High resistance against extrusion. 4. Low compression set. 5. Suitable for hardest working conditions. 6. Sufficient lubrication due to pressure medium between the sealing lips. 7. lncreased sealing performance at zero pressure. 8. Air penetration from outside is largely prevented. 9. Easy installation.

Easy installation rod seal is external seals that prevent leakage from the cylinder. EU rod seal for piston rods in pneumatic cylinders combines three functions: sealing-wiping-fixing.
Rod seals are static seals installed in glands or housings to prevent the leakage of fluid from within a cylinder to the outside as the rod cycles.
Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
This product can fully meet the pressure working conditions of current hydrogen compressor transportation equipment, ranging from 0 to 90MPa, and the sealing element will not extrude and deform, with good sealing performance.
The oil scraper ring is a part located at the rear of the pump packing seal.
BT Seal is a static seal that is used to seal rough casing and tubing. It is constructed from an elastomer with anti-extrusion spring bonded within it. Springs are available in stainless steel, elastomer could be HNBR or NBR.
Hammer union seals are used for hammer joint type pipe connections to establish flow lines and prevent leakage.
Spring energized PTFE seals consist of variety of jacket profiles and spring types. It can achieve the sealing effect compensation under different pressure conditions by spring energizer.
