ABSTRACT OF THE DISCLOSURE A sealing gland construction for use in connection with hydraulic unit joints. Receptacles are provided at the joint for enlarged and compressible heads disposed on each end of the sealing gland. One receptacle is located on an inner wall of a female or bell end of one pipe and another receptacle is located on the exterior wall or a male or spigot end of an adjacent pipe. The enlarged heads of the sealing gland extend perimetrally around their associated female and male ends of the pipe and are adhesively secured within the receptacles. By making the compressible heads larger than the dimensions of the receptacle they are maintained under compression both horizontally and vertically. In the assembled joint position, the male end and its receptacle have been inserted into the female end past its receptacle so as to effect a fluid seal which is encased within the walls of said pipes and which remains sealed even in the event of a slight discoupling of the joint. In another embodiment, only the female pipe end is provided with a receptacle for an enlarged, compressible head. The opposite end of the sealing gland is clamped and adhesively secured to the male end. In the assembled position, the point of attachment is inserted beyond the receptacle in the female end to reach a comparable result.
