What are the advantages of rubber O-rings than other types of seals?

Compared with other types of sealing rings, rubber O-rings have the following advantages:

--Suitable for a variety of sealing forms: static sealing, dynamic sealing

Suitable for all kinds of materials, the size and groove have been standardized, and the interchangeability is strong. 　　

--Suitable for a variety of motion methods: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion) 　　

--Suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media 　　

Through the selection of appropriate rubber materials and appropriate formulation design, an effective sealing effect on oil, water, air, gas and various chemical media can be achieved. The temperature range is wide (-60 ℃～+220 ℃), and the pressure can reach 1500Kg/cm2 (used together with the reinforcing ring) in fixed use.　　

--Simple design, compact structure, convenient assembly and disassembly 　　

The cross-sectional structure of the rubber O-ring is extremely simple, and has a self-sealing effect, and the sealing performance is reliable.　　

Since the structure of the rubber O-ring itself and the installation part are extremely simple and standardized, the installation and replacement are very easy.　　

--Many varieties of materials 　　

You can choose according to different fluids: nitrile rubber (NBR), fluoro rubber (FKM), silicone rubber (SIL), ethylene propylene diene rubber (EPDM), chloroprene rubber (CR), natural rubber (NR), hydrogenated Nitrile rubber (HNBR), butyl rubber (IIR), fluorosilicone rubber (FLS), etc.
