Abstract

A method of forming a seal between the confronting planar sealing surfaces on two annular structural members which are drawn together by axially extending bolts is described comprising the steps of: forming a seal assembly by locking a toroidal, crushable seal member within a substantially flat annular spacer member against an annular shoulder formed on the inner diameter thereof with an annular resilient member seated in a radially extending groove in the inner surface of the substantially flat annular member, the flat annular member being axially thinner than the toroidal, crushable seal member; placing the sealing assembly between the planar sealing surfaces and positively aligning the assembly relative to the axially extending bolts; and tightening the bolts to draw the planar sealing surfaces toward each other and into contact with the flat annular member while crushing the toroidal, crushable seal member to form a seal between the planar sealing surfaces.
