Molded seals

Main seal kits: Hallite + NOK. This is the seal combination with which we are most familiar. We can find most solutions suitable for the cylinder under such as high-pressure and high-temperature conditions.

You can purchase suitable replacement seal rings all over the world, and we have in-depth cooperation with these two brands to achieve good cost control.

Also,Merkel and Parker seals available.

Turned seals

BOS Hydraulics is a custom hydraulic cylinder factory. If there is no brand seal in stock or a suitable size, we will use turning rings to meet the needs of the cylinder.

Misconception: Many people think that the quality of turned seals is not as good as that of molded rings.

This is worth discussing. Turned rings are more expensive and more suitable for use in some specific environments.

Today’s industrial production is very mature.

BOS Hydraulics strictly controls quality. If you need it, we can provide you with better turned seals to accompany your professional cylinders.
