Mechanical Joint Pipe

The "original" modern pipe joint, dating back to 1925, is known as the Mechanical Joint. It primarily connects fittings, valves, and similar appurtenances to a pipeline. The nuts, bolts, and gland featured in the joint create a permanent watertight seal capable of withstanding pressures of up to 350 psi and more. This seal is achieved through a "stuffing box" compression of the gasket into its counterpart triangular recess of the joint.
