ORK Colored High temp silicone o rings home depot for PVMQ Material Manufacturer
Type: O Ring
Size: ID X CS, OD=ID + 2XCS
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
Silicone O-Ring (MQ, VMQ, PVMQ) Material Description
Physically, silicone o-rings are based on silicon, an element derived from quartz. To create this class of synthetic
elastomers, pendant organic groups such as methyl, phenyl, and vinyl are attached to silicon atoms. Different
additions of side chains can achieve significant variations in properties. Silicone o-rings have excellent heat,
ozone, and corona resistance and have good dielectric stability and resistance to many oils, chemicals, and
solvents. Silicone o-rings maintain the best flexible properties at low temperatures but have low tensile
strength and low wear and tear resistance.
Silicone o-rings may also come in a metal detectable variation, while retaining the same qualities as the
general silicone o-ring compound. RUICHEN Sealing supplies silicone o-rings that are compliant with FDA
standards, and are suitable for use in food and beverage production lines, as well as medical and
pharmaceutical manufacturing. Both silicone and metal detectable silicone o-rings meet FDA compliance.
