Abstract

887,760. Pipe couplings. BROWN BROWNALL Ltd., DONALD. Feb. 15, 1961 [April 20, 1960], No. 13786/60. Class 99(1). In a coupling of the kind incorporating a sealing ring h which cuts into and seals on to the surface of a pipe b which is to be coupled up as a nut d is tightened, the nut has a relatively coarse screw thread which engages a similar thread on a coupling body a and a relatively fine screwthread #which engages a backing ring g adapted to bear on, or is integral with, the sealing ring to cause the latter to cut into the pipe. Specification 753,708 is referred to.
