Pipe insulation coupling with sealing mechanism

A pipe insulation coupling for supporting a pipe and for coupling adjacent ends of pipe insulation tubing, the pipe insulation coupling comprising:

• an outer tube wall extending along a longitudinal axis between a first end and a second end, wherein the outer tube wall is split longitudinally from the first end to the second end to define a first body portion and a second body portion;
• a first planar interior wall extending inwardly from the outer tube wall transverse to the longitudinal axis between the first and second ends, wherein the first planar interior wall includes a center bore for receiving the pipe and the first planar interior wall provides an abutment for the adjacent ends of the pipe insulation tubing;
• and
• a sealing mechanism extending longitudinally between the first and second ends of the outer tube wall for securing the first and second body portions together to retain the pipe and the adjacent ends of the pipe insulation tubing, wherein the sealing mechanism comprises an outward sealing face at an end of the first body portion and an inward sealing face at an end of the second body portion, wherein when the pipe insulation coupling and the pipe insulation tubing are installed on the pipe, the sealing mechanism forms an air-tight seal to prevent air from entering the pipe insulation coupling;
• and
• a base structure integrally secured to the outer tube wall, wherein the base structure includes a horizontal planar face and a vertical planar face extending from the horizontal planar face to each side of the outer tube wall, the vertical planar face and the outer tube wall forming an outer profile shape configured to contour to a U-shape clamp placed around the pipe insulation coupling such that the vertical planar face contacts the U-shaped clamp.
