Chloramine Resistant O-Rings, Products and Compounds
As technology advances, we change and promote a safer, more efficient way to live. This progression however, directly effects existing standards and methods, forcing them to acclimate to a new environment, creating a new industry need. In the Consumer Industry, water treatment facilities are using chloramine as a primary means to disinfect potable water in lieu of free chlorine.

Encapsulated O-Rings 
An encapsulated o-ring is a two component circular seal with a round cross section. The elastomers impart memory to the seal and are encapsulated in a Teflon jacket. The encapsulation protects the elastomer from hostile environments. Compared with solid o-rings, Teflon encapsulated o-rings function in a broader range of environments.

Hollow O-Rings
Darcoid works with Parker that does precision extrusion and spliced products that offer an ideal, costeffective sealing solution for many applications. These include low-closure force seals, large diameter profiles that cannot be molded, hollow cross-section cord or requirements for non-standard O-rings and other extruded profiles with an inside diameter larger than 2.500 inches.

Consumer technology changes and improves our way of life. However,these advancements can sometimes alter existing service environments, disrupting rubber elastomer properties. For example,chloramine is one primary method of disinfecting potable water at treatment facilities. Chloramine is produced by combining chlorine and ammonia. It is weaker than chlorine,but provides more stability,extending disinfectant benefits throughout a water utilities distribution system.
