1】 It has quite excellent compressibility and resilience.It only need a minimum of fastening force to play a effective sealing role under the operating condition of low temperature and low pressure.It also wont split when it was dismantled from the flange.
2】 It can also achieve good sealing effect when uses to seal the uneven and impaired flange surface.
3】Since the rubber has excellent expansionary and resistance to permeability,it can form effective sealing to resist gas and fluid resistance.
