Model Number:
AS568 & PG Standard O-Rings
Freely Sealing Usage EPDM O Ring Seals for Customized Waterproof and Oil-Proof at ORK
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),
natural rubber (NR), etc.
--low cost
--The dynamic friction resistance is relatively small

peroxide cured systems).
*Application
In phosphate-ester based hydraulic fluids and glycol based brake fluids systems Ethylene
Propylene Rubber is good choice for sealing parts. EPDM is also is usually used in hot water or
steam applications up to 150 C.
