ABSTRACT:
A desirable seal structure for use in forming a seal around the exterior of a pipe or the like can be constructed so as to use a retainer member, a compression member, a sealing member located generally within the retainer member and generally between the compression and retainer members and bolts for compressing the retainer and compression members against the sealing member. The compression and retainer members are provided with beveled surfaces which are complementary to corresponding tapered surfaces on the sealing member. The sealing member is shaped so that it will move inwardly when compressed between the compression and retainer members.
