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.
