Black Excellent Abrasion Resistance NR Nature O Ring Rubber for
Injectors
What is O Seal ring ?
O-ring advantage:
O-rings have the following advantages compared to other types of
seals:
-- Suitable for a variety of sealing forms: static seal, dynamic
seal
Suitable for a variety of materials, sizes and grooves have been
standardized, interchangeable
- Suitable for a variety of sports: rotary motion, axial
reciprocating motion or combined motion
(such as rotary reciprocating combined motion)
- Suitable for many different sealing media: oil, water, gas,
chemical media or other mixed media
Effective sealing of oil, water, air, gas and various chemical
media through the selection of
suitable rubber materials and appropriate formulation design. The
temperature range is wide
(-60 ° C ~ +220 ° C), the pressure can be up to 1500Kg / cm2 when
used in fixed use (combined
with the reinforcing ring).
--Simple design, compact structure, easy to assemble and
disassemble
The O-ring cross-section structure is extremely simple, and has a
self-sealing effect, and the sealing
performance is reliable.
Since the O-ring itself and the mounting structure are extremely
simple and standardized, installation
and replacement are very easy.
--More varieties of materials
Can be selected according to different fluids: nitrile rubber
(NBR), fluororubber (FKM), silicone
rubber (VMQ), ethylene propylene rubber (EPDM), neoprene (CR),
butyl rubber (BU), poly
Tetrafluoroethylene (PTFE), natural rubber (NR), etc.
--low cost
--The dynamic friction resistance is relatively small
NR/Nature material
Natural rubber is a high molecular weight polymeric substance with
viscoelastic properties. It
shows all the reactions of an unsaturated polymer and gives
addition compounds with halogens,
ozone, hydrogen chloride and several other reactants that react
with olefins.
An interesting reaction of natural rubber is its combination with
sulfur— known as vulcanisation.
This reaction converts the plastic and viscous nature of raw rubber
into elastic. Vulcanized rubber
will have a very high tensile strength and comparatively low
elongation. Its hardness and abrasion
resistance also will be high when compared to raw rubber. Because
of the unique combination of
these properties, natural rubber finds application in the
manufacture of a variety of products.

O Seal Ring Operating Temperature
Application: mainly used in manufacturing and automobile so as to electrolic
aspects with regard to all
kinds of heat-resistant and water-assistant products, such as
rubber hoses and dustproof washer seals, etc.
