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.

The UNIVERSAL CMP DP Coupler is a four-compression band, heavy duty (3-ply, 180 mil thickness) coupler designed to join CMP/CSP (both rerolled and non-rerolled/plain/cut end) to any other type of pipe in that nominal size with an OD up to that of corrugated HDPE/HDPP and down to that of SCH40 PVC.

NOTE: For CMP-to-CMP connections go to MarMac CMP Pipe Couplers (soil-tight and water-tight versions available).

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: 12"
• Connection: CMP to HDPE/HDPP/PVC (Size on Size)
• Strong, permanent, shear & puncture resistant
• Easily installed & immediately inspectable
• Tens of thousands in use today with nearly a 100% success rate
• Full-perimeter, positive seal = infiltration-proof
• Specially formulated mastic layer
• Heavy-duty, high quality construction
