Correlation of O-Ring Materials
While choosing an O-ring for your application, a
ton of significance ought to be put on the
material of the seal being utilized. Since a
legitimate fixing activity is profoundly reliant
upon the state of your O-ring, an O-ring material
should be decided to best suit the working
climate of your application. A portion of the
normal materials used to make O-rings are nitrile
elastic or Buna-N, Viton(r), silicone elastic,
neoprene, and PTFE or Teflon(r).

Picking an O-ring material is reliant upon a few
unique elements, however two of the most basic
variables are the working temperature range that
O-rings are exposed to and the various synthetics
they might be presented to. A few extra factors
that assume a part in the choice of an O-ring
material incorporate protection from tearing and
scraped spot, and daylight or maturing. Since
most O-ring materials respond distinctively to
different conditions as well as synthetics, every
material enjoys its benefits and burdens.

Nitrile Elastic Perhaps of the most widely
recognized material used to make O-rings is
nitrile elastic or Buna-N, which is an engineered
elastic copolymer. This material has fantastic
protection from water, pressure driven liquids,
solvents, oils, and other oil based commodities.
This component, combined with its working
temperature scope of between - 65 degrees F to
275 degrees F, has made nitrile elastic one of
the most broadly utilized elastomers to make
O-ring seals. In any case, this material has its
limits nitrile is for the most part not
suggested for applications where it very well may
be presented to daylight and ozone, as well as
specific synthetics, which incorporate ketones,
esters, and sweet-smelling hydrocarbons.

Moreover, its helplessness to ozone additionally
makes it important that nitrile elastic seals are
not put away close to electric engines that
typically create ozone. Its high protection from
oil based goods and sensible protection from
temperature has prompted Nitrile elastic O-rings
turning into the best option for different
applications in the car business.
6
Silicone Elastic Silicone rubbers are an
assortment of elastomeric polymers created from
silicon, hydrogen, oxygen, and carbon. Silicones
for the most part have unfortunate protection
from scraped spot and tearing, as well as low
elasticity in addition to a high coefficient of
rubbing - highlights that make them unacceptable
for dynamic fixing applications. Notwithstanding,
its extraordinary protection from outrageous
temperatures, going from as low as - 150 degrees
F to as high as 500 degrees F, makes it ideal
for applications where seals are presented to
high dry warms, as in auto parts and cookware.
7
Viton(r) Viton(r) is one more engineered
elastic normally utilized for making O-ring
seals, which is a sort of FKM elastomer. This
elastomer's magnificent protection from solvents
and oils, as well as its protection from
expansive working temperature ranges, has made it
famous for use in a few applications. However its
working temperature goes from - 10 to 400
degrees F, seals produced using this material are
referred to endure temperatures as high as 600
degrees F for brief time frames. This mix of
properties settles on Viton an ideal decision for
high-temperature applications as well as
applications presented to a wide range of
liquids. One such application that has embraced
Viton O-rings is SCUBA jumping, where the O-ring
seals are utilized in the jumper's air tank. Be
that as it may, however Viton is viable with most
hydrocarbons, it is by and large not viable with
ketones and natural acids.
8
PTFE One fluoropolymer usually used to
fabricate O-rings is PTFE, or Teflon(r), as it is
normally known. PTFE is quite possibly of the
most artificially idle material used to make
O-rings and is very impervious to oils, solvents,
bases, acids, steam, and different synthetic
compounds. Its unrivaled protection from scraped
area and tearing makes it ideal for dynamic
fixing applications. In any case, there are a
couple of disadvantages to utilizing PTFE
O-rings. The first is their powerlessness to be
packed as successfully as other normally utilized
O-ring materials, which converts into wasteful
fixing. The other significant weakness of this
material is its unfortunate virus stream
qualities under consistent strain. In any case,
its compound obstruction and low coefficient of
contact have made it a well known fixing choice
in numerous valves and different applications.
9
Neoprene Neoprene is one more engineered
elastic that is routinely used to make O-ring
seals. This elastomer is impervious to creature
and vegetable fats, as well as most oils and
solvents. In any case, O-ring seals produced
using this material are by and large not
prescribed for applications that include openness
to ketones, esters, sweet-smelling hydrocarbons,
and solid oxidizing acids.
10
Normal Elastic As of now, normal elastic
O-rings are seldom utilized because of the
appearance of engineered elastomers, for example,
Nitrile elastic and Viton. Normal elastic can be
utilized with creature oils, vegetable oils, and
most oxidizing synthetics. In any case, it isn't
suggested for use with oils, oil solvents,
sweet-smelling hydrocarbons, and applications
that request openness to daylight or ozone.
11
These recorded materials are usually involved
elastomers for making O-rings, however different
materials, like Kalrez, are additionally utilized
in specific extraordinary applications. Kalrez is
an ideal trade for Viton in applications that
have working temperatures of up to 500 degrees F.
Additionally, there are different elastomers
utilized for explicit fixing purposes. Anything
the material you decide for your application,
care ought to be taken to guarantee its
similarity with working temperatures, liquids,
and the climate.
12
The criticality of picking the best material for
your application is immediately obvious when we
consider the reason for the Space Transport
Challenger fiasco. This misfortune was brought
about by the disappointment of an O-ring that
lost its versatility and became fragile because
of a surprising decrease in encompassing
temperature. However most O-ring disappointments
probably won't prompt the death toll at standard
with this calamity, there is no denying the
unmistakable financial misfortune brought about
by a bombed machine or gadget.
