We are offering gaskets.Our work at the frontier of sealing technology gives us a clear understanding of the roles that gaskets must play, for example:if joint faces are absolutely flat and aligned true.if flanges do not distort under load.if loaded bolts do not stretch or relax there is no need for a gasket, because the joint will be perfect. in the real world, such perfection is very expensive to achieve and almost impossible to maintain. Therefore a gasket is the most practical and cost effective way to seal a bolted flange joint.
