The sealing performance of Dewees sealed U-RING is good, but it is easy to roll when used alone, so it needs to be used together with tin bronze supporting ring. Its friction resistance is large and increases with the increase of working pressure. Therefore, U-RING is only suitable for hydraulic cylinders with low working pressure or low moving speed.
We have a full range of materials and a full range of standard sizes welcome to contact us.
