Black Aflas or Kalrez Rings Resistant to Strong Acid and Alkali FFKM 75 shore A O Ring

Introduction for O Rings

1.The O-ring is an annular seal having an O-shaped cross section, the size of which

is determined by the inner diameter ID and the wire diameter CS.

2.O-ring size calculation: outer diameter = inner diameter + 2 x wire diameter

(OD = ID + 2x CS).
 

3.The purpose of using O-ring seals is to prevent leakage and loss of liquids or gases.

4.O-rings are the most commonly used type of seal because of their simplicity, convenience,

and small installation space. As long as the groove design and material selection are correct,

and the operating conditions are within the temperature range of the rubber material, the seal

can have a long-term sealing effect in the static or dynamic seal.

Following elastomers can be use in O ring :
* Aflas® or Kalrez®(FFKM)
* Acrylate Rubber(ACM)
* Butyl Rubber(IIR)
* Ethylene-propylene (EPR, EPDM)
* Ethylene Acrylate Rubber(AEM)
* Fluorocarbon (FKM/FPM/FKM)
* Fluorosilicone(FVMQ)
* Hydrogenated Nitrile (HNBR)
* Neoprene Rubber(CR)
* Nitrile Rubber (Buna-N/NBR)
* Natural Rubber(NR)
* Polyurethane(PU)
* Silicone Rubber
* Styrene-butadiene Rubber (SBR)

We can make 30~90 shore A for hardness
