Description

MarMac Dissimilar Pipe Couplers (DP Couplers) are engineered to join, seal, and restrain the connections between pipes of differing material and/or pipes of varying nominal size*. These unique, external sealing bands are reinforced and prevent infiltration into gravity-flow drainage systems.

*While dependent upon pipe material(s) and/or overall pipe diameter(s), the difference in diameter must not exceed 15% or 8″ to allow for proper step-down.

DP Couplers integrate several unique components into a single, customizable, full-perimeter, external sealing band. Our specially-formulated, rubberized mastic aggressively adheres to all known pipe surfaces, providing a positive seal to battle infiltration. The coupling is reinforced with a sheet of durable, woven polypropylene which provides shear and puncture resistance. They are constructed with four integrated compression bands, which when tightened, form a mechanical seal, permanently bonding the mastic to the pipe wall.

  • Size: 60"

Some of our most popular pipe jointing scenarios are below. This is by no means a comprehensive list or a suggestion that these connections perform better than others. Dissimilar Pipe Couplers are able to connect virtually any structurally sound pipe material with another. DP Couplings are also a great choice for two pipes of the same material, but with differing nominal diameter. The aforementioned diameters however, must be reasonably close to account for proper step-down/reduction.

SPECIFICATION

DP Couplers are strategically manufactured with cross-laminated polyethylene, woven polypropylene, rubberized “cold-flow” mastic, as well as integrated compression bands, similar to MarMac’s PolySeal couplers. DP Couplers are three-ply with a total thickness of approximately 180 mils. 

INSTALLATION

The coupler shall be placed around the pipe, mastic side to the pipe, spanning the joint. The protective release film shall be removed and the coupler applied with the overlap at the top of the pipe. The straps shall be secured (outside straps first) on the larger outside diameter pipe (when applicable) with the proper tools. Then, the straps on the outside of the smaller outside diameter pipe shall be secured. The inside straps shall be tightened last. The closing flap shall cover the exposed strap work area, completing the joint.
