The method of joining two plastic members comprising forming said members for frictional engagement therebetween in a fluid-tight zone of interference with a tapered crevice leading to said zone of interference, fitting said members together in frictional engagement with said zone of interference serving as a fluid-tight barrier, and introducing a solvent into said crevice at a point remote from said zone of interference to form a solvent bond with said zone of interference serving as a barrier against contact between said solvent and any flowable material or objects on the opposite side of said zone.
