When to use a neoprene o-rings or oil seals
Sometimes it is hard to know which elastomer to choose for an
application. Depending on the circumstances, neoprene can offer some
definite advantages. Here are some points to consider when deciding
which elastomer to use.
If you need to seal refrigeration fluids, a neoprene o-ring can be a
good choice because it has excellent resistance to Freon and
ammonia.dust oil seals high quality
If you need an o-ring with a good temperature range, neoprene has heat
resistance up to 250 degrees F. and remains flexible down to -40 degrees
F.
Because a neoprene o-ring has this broad temperature range, and because
it is inexpensive, it can be used in many general service applications.
A neoprene o-ring has outstanding physical strength and resists the tearing and cracking caused by flexing and twisting.
With its excellent resistance to sunlight, ozone, oxygen, nok seal,carbon dioxide and weathering, a neoprene o-ring is an outstanding choice for outdoor applications.
Neoprene works well if you need an o-ring with low gas permeation.dust oil seals high quality
If you are using silicone oils or greases in your application, neoprene
might work well because it has a high resistance to these fluids.
Most other elastomers are resistant to either petroleum based lubricants
or oxygen, but not both. A neoprene o-ring will serve you well if you
need resistance to both of these.
If you have an underwater application a neoprene o-ring will provide you
with good resistance to water and water solvents at low temperatures.cap seal.
Since neoprene seals have a greater resistance to fire than hydrocarbon
based rubbers, they are a good choice for sealing fire doors.
If your application calls for rubber to metal bonded parts,car seal, neoprene has excellent adhesion qualities and can be successfully bonded to metal to make whatever parts you need.dust oil seals high quality.
Do not choose neoprene for environments that contain aromatic
hydrocarbons (benzene), chlorinated hydrocarbons (trichloroethylene) or
polar solvents (ketones, esters, ethers and acetones).
