For Excavator Oil Seal Kit O-Ring Box

Short Description:

O-rings produced from rubber materials are collectively referred to as rubber O-rings. Its function is mainly to seal, with excellent sealing performance and high working life. The working life of dynamic pressure seal is 5-10 times higher than that of conventional rubber seal products, and the maximum life is up to tens of times. Under certain conditions, it can have the same life as the sealing base.

Our advantage

Through the selection of appropriate rubber materials and appropriate formulation design, effective sealing of 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 in fixed use (used together with the reinforcing ring).

O-ring advantages

1. Suitable for a variety of sealing forms: static sealing, dynamic sealing,

2. Suitable for various materials, the dimensions and grooves have been standardized, and the interchangeability is strong

3. Suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion)

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

material Low
NBR -40 120 Good resistance to alcohol,amines, petroleum oils, and
gasoline over a wide range of temperature. Also good resistance to caustic salts and fair acid. Poor in strong oxidants, chlorinated hydrocarbons, ketones, and esters
HNBR -25 140 HNBR is made from NBR by hydrogenation. It has high
temperature resistance, abrasion resistance and good
physical properties.
ACM -25 150 It is used in diaphragm, hose for automotive application.
Good resistance to heat, ozone and oil. Generally
attacked by water, alcohol, glycol and aromatic
hydrocarbons. The molecular structure contains ethyl acrylate (EA). Butyl acrylate (BA), and methoxy ethyl acrylate (MEA). High BA content get better low temperature resistance, and high MEA content get more oil resistance.
EPDM -40 125 Stable in polar fluids (alcohol, ketone, and glycol),
and hydrochloric acid. Due to the low specific gravity, it can compound with large amount filler.
VMQ -60 125 The most widely temperature ranges for application.
Good weather and ozone resistance, but poor mechanical property and chemical resistance.
FKM -20 250 Fluoroelastomers have a high degree of chemical
stability and are currently the best media resistance
of any elastomer. Type 26 fluoroelastomer resistant
to petroleum-based oils, diester oils, silicone ether
oils, silicic acid oils, inorganic acids, most organic, inorganic solvents, drugs and so on
