O Ring PTFE Coatings

O rings, seals and sealing systems can all benefit from the use of a lubricant to aid assembly and to eliminate pinching and unwanted friction, enhancing their sealing performance and reducing wear. The use of rubber seals creates problems for quality and efficiency in today’s demanding industries and reduction in assembly time and the elimination of noise is of primary concern to design engineers.

To solve these problems the friction coefficient must be lowered to:-

· Ease assembly

· Assure that the seal is seated properly without tension that may cause premature wear, or defective sealing

· Eliminate the risk of rupture (as with the Fluorosilicone)

· Eliminate stick-slip concerns (noise and squeaks) where micro tapping is present.

 Both water and solvent-based rubber compatible products are available from Best Fluoro. The choice of product depends on the desired endurance, the risk of contact with dust, and the transfer of product associated with handling. The film created is barely visible but many products are available with the UV tracer material so that it can be detected and monitored on the assembly line.
