Neoprene O Rings have a working temperature range -50 to +120 degrees C.
Neoprene (Chloroprene) O ring are commonly used in the refrigeration industry and have very good resistance to ammonia, carbon dioxide, refrigerants, silicone oils and greases and water.
Neoprene resists degradation more than natural or synthetic rubber.This relative inertness makes it well suited for demanding applications such as gaskets, hoses and corrosion resistant coatings It can be used as a base for adhesives noise isolation in power transformer installations, and as padding in external metal cases to protect the contents while allowing a snug fit. It resists burning better than exclusively hydrocarbon based rubbers,
O-rings seal by mechanical deformation that creates a barrier to a fluid’s potential leak path between two closely mated surfaces. O-rings are typically installed in a groove that’s machined or molded in one of the surfaces to be sealed. Their rubber-like properties let the devices compensate for dimensional variations in the mating parts.
When properly sized, the clearance between the surfaces is less the OD of the O-ring. Thus, as the two surfaces contact, forming a gland, they compress the O-ring, which deforms the round cross section. This diametrically squeezes the seal, and the resulting force ensures surface contact with the inner and outer walls of the gland.
