DMS Seals giant o ring in highly aggressive chemical processing

Company Advantages
1. DMS Seals giant o ring is designed in a flexible and sophisticated manner. It is built with a simple structure, varied combination mode, and vigorous color match to accommodate the accordant yet unique space style.
2. DMS Seals is manufactured at a high-quality level. It meets the standards stipulated in the National Basic Safety Technical Specifications for Garments Products.
3. The design of DMS Seals is guided under the principle of biomechanics. The theory of the anatomic structure of the foot and ankle all are considered during the design.
4. The design of DMS Seals is elaborate. It addresses the following areas of research and inquiry: Human Factors (anthropometry and ergonomics), Humanities (psychology, sociology, and human perception), Materials (features and performance), etc.
5. It is good at color fastness after washing. Prior to production, the fibers are pre-washed with clean water to check for firmness and rewash with a specific chemical liquid at a certain temperature.
6. This product effectively resists pilling, which is the creation of small balls of fiber on the surface of the bedding.
7. This product does not fade, that is, it does not fade after multiple washing, but it will become soft.
8. People who want to adopt a new, natural lifestyle, this product is able to help them look and feel natural.
9. The product is able to help lower costs– uses less energy for the work it does, lowering hospital's power bill.
10. Even though used for a long time, the product does not require frequent replacement due to its outstanding tightness and durability.

1. Installation Recommendation 

2. Application and properties

Double acting seals, the sealing effect is achieved by the deformation of the section of the O-Rings, and the deformation is determined by the depth of the installation groove. Under pressure, the O-ring has a large surface tension like liquid, used for static sealing more. It is only recommended for better conditions in dynamic applications. System lubrication, pressure, temperature, sealing clearance, speed, medium and surface quality of metal parts determine the service life of O-Rings. It is not recommended if the lubrication is not sufficient during rotary motion.

3. Standard materials

Silicone
