Debond rubber seal from steel oil seal ring

Objective

Debond a fluorocarbon rubber seal from a carbon steel oil seal 

End Product

oil seal ring

Equipment

• Ambrell 2.0 kW induction heating system, equipped with a remote workhead containing two 0.66µF capacitors for a total of 1.32µF 

• An induction heating coil designed and developed specifically for this application. 

Materials

4” (10.2cm) OD carbon steel oil seal with a fluorocarbon rubber seal 

Temperature

1200 ºF (649 ºC)

Frequency

179 kHz

Testing

A two turn helical coil is used to heat the steel oil seal. The seal is placed in the coil and heated for 8 seconds. Once the seal had cooled the rubber seal is easily peeled from the steel

in one piece. 

Benefits

Induction heating provides:

• Highly accurate placement of heat, no effect to surrounding components

• Faster and more efficient

• Even distribution of heating
