Black PU Aging Resistance Polyurethane Rubber for Shower Head
Rubber O Ring
What is O Seal ring ?
O-Ring is a simple and versatile ring-shaped packing or sealing
device with a circular cross section.
The opposite side of an O Ring are squeezed between the walls of
the cavity or gland into which the
O -Ring is installed. The zero clearance within the gland provides
an effective sealing and blocking
the flow of liquids, and gases through the glands. Internal
pressure dynamics and static. O-rings are
available in a variety of materials, in both standard and custom
sizes.
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
