Black Neoprene Good Compression Resistance CR Rubber Fill Valve Washer
Material Description for CR/Neoprene/Polychloroprene Fill Valve Washer
Neoprene (Polychloroprene)
Neoprene or Polychloroprene is a group of synthetic rubbers which exhibit excellent chemical constancy
and maintain flexibility over a wide temperature range. Neoprene can be used in a wide selection of
applications, such as laptop sleeves, orthopedic braces, electrical insulation, liquid, and sheet applied
elastomeric membranes or flashings, and automotive fan belts. Its chemical inertness makes it well suitable
for industrial applications such as gaskets, hoses, and corrosion-resistant coatings.

Product Introduction for CR/Neoprene/Polychloroprene Valve Fill Washer
A wahser is a mechanical seal which fills the space between two or more mating surfaces. They are generally
used to prevent leakage from, or into the joined objects while under compression.
A wahser allows "less than perfect" mating surfaces on machine parts where they can fill irregularities.wahser
are commonly produced by cutting from sheet materials. Traditionally Asbestos was a common wahser material
for applications such as high pressure steam systems. Due to the health hazards associated with it, compressed
non asbestos fibres (CNAF) are now used in its place.
Ideally a wahser should be made from a material that is to some degree yielding, such that it is able to deform
and tightly fill the space it is designed for. This includes any slight irregularities. Some joints may also require
an application of sealant directly to the wahser surface to function properly.
