Polyurethane PU TPU Piston Rod Seal UN Hydraulic Seals For Cylinder
Polyurethane (PU) is a special material that offers the resilience of rubber combined with the toughness and durableness. It allows people to substitute rubber, plastic and metal with PU. Rod & Piston seals are equal lip-seal which can be used for both piston seal and rod seal.They’re also the most critical seals on any type of fluid power equipment preventing leakage of fluid from within the cylinder tothe outside. Leakage through the rod or piston seal can reduce equipment performance, and also in extreme cases can cause environmental issues.

Proper use of Polyurethane seal,should pay attention to the following points:
1. Improve lubrication quality, control oil pressure, temperature and flow, and strengthen oil filtering. 2. Use fuel and lubricants that meet the requirements. 3. In order to control the temperature state of the diesel generator set, it is not suitable to work under the condition of overcooling or overheating. In cold weather, the diesel engine should be preheated before starting, and the crankshaft should be turned by hand to allow the oil to enter the friction surface. 4. The surface quality of the piston rod and journal should be strictly guaranteed. 5. The piston rod clearance should be appropriate. If the generator set is too large, it will cause an impact, and if the generator set is too small, the lubricity will deteriorate.

We have implemented a quality and management system that meets the strictest standards. We have trade department, engineering department, production department, after-sales service department, more than 50 inspectors to control the quality, test each batch of materials before use, to ensure whether the key physical characteristics meet the requirements 100% inspection before shipment.
