48" MarMac Double-Wide PolySeal Coupler 4867RCD

Buy Now!
  • SKU: MM-POLY-48DBL
  • Brand:

  • Product Description:

    MarMac PolySeal is a flexible, high-strength pipe coupling that permanently seals and restrains corrugated plastic pipe. PolySeal Couplers are over-engineered, reinforced external joint seals designed to connect HDPE / HDPP corrugated pipe, while remaining both infiltration proof and exfiltration resistant. PolySeal Couplings are perfect for cut & butt joints, field repairs, new detention systems, and more. 

    MarMac’s Double-Wide PolySeal Couplings are heavy-duty 3-ply as they are manufactured with an additional layer of polyethylene and mastic. Nearly twice the width of a standard PolySeal, our Double-Wide PolySeal Coupler comes with five integrated compression bands, as opposed to three with our Standard coupler.

    Our Double-Wide PolySeal coupler has five integrated compression bands. Sizes under 30″ are standard-duty and use hose clamp bands made of high-strength 409 or 304 stainless steel. Heavy-duty sizes over 30″ contain an additional membrane layer of polyethylene and mastic, and utilize built-in ratchet straps.

    Common uses include repairs, such as instances where pipe ends have minor damage or to cover small punctures in a pipe caused by fork trucks or similar. Additionally, Double-Wide PolySeal can be used in place of standard PolySeal to make a stronger, stiffer joint.

    • Fits corrugated HDPE & HDPP pipe
    • Size: 48"
    • Compression Bands: 5 Built-In Ratchet Clamps
    • Infiltration-proof exfiltration-resistant
    • Easily installed & immediately inspectable
    • Millions installed today with nearly a 100% success rate
    • Permanent protection with proven performance
    • Strong, shear & puncture-resistant

    SPECIFICATION

    PolySeal is manufactured with interval layers of our rubberized mastic, specially formulated to adhere aggressively to all known pipe surfaces. A sheet of puncture and shear-resistant woven polypropylene, and an outside backing of cross-laminated polyethylene makes PolySeal resistant to most acids and bases (additional protection available with Chemical Resistant PolySeal). The integrated compression bands mechanically “lock” into the corrugations of the pipe, bonding the mastic to the pipe wall, and forming a permanent seal.

    The minimum length of a PolySeal Coupler is the circumference of the outside diameter of the pipe, plus eight inches for overlap.

    INSTALLATION

    Surface preparations: Inspect the outside of the joint. Brush surface as needed to ensure it is free of debris. If installing on horizontal pipe, dig a bell hole for complete access to the joint.

    The coupler shall be placed around the pipe with the mastic side to the pipe wall and spanning the joint, while centered on the joint gap to be sealed. The protective film shall be removed and the coupler applied with the overlap at the top of the pipe. The tensioning straps shall be aligned between the pipe corrugations and tightened. The closing flap protective film shall be removed and the closing flap shall cover the exposed straps and the work area.

  • SKU: MM-DP-48SPECIAL
  • Brand:

  • Product 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: 48"

    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.

    1. RCP to HDPE/HDPP
    2. CMP to HDPE/HDPP (Must note if CMP has annular / re-rolled or spiral  /non-rerolled ends)

    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.

    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.

    1. RCP to HDPE/HDPP
    2. CMP to HDPE/HDPP (Must note if CMP has annular / re-rolled or spiral  /non-rerolled ends)
    3. CMP to RCP  (Must note if CMP has annular / re-rolled or spiral / non-rerolled ends)
    4. PVC to HDPE/HDPP

    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.

  • SKU: MM-POLY-06STD
  • Brand:

  • Product Description:

    MarMac PolySeal is a flexible, high-strength pipe coupling that permanently seals and restrains corrugated plastic pipe. PolySeal Couplers are over-engineered, reinforced external joint seals designed to connect HDPE / HDPP corrugated pipe, while remaining both infiltration proof and exfiltration resistant. PolySeal Couplings are perfect for cut & butt joints, field repairs, new detention systems, and more. 

    MarMac’s Standard PolySeal is a high performance, external joint coupler designed for the prevention of infiltration and resistance of exfiltration at joints of common HDPE & HDPP corrugated pipe.

    Our standard PolySeal coupler has three integrated compression bands. Sizes under 30″ are standard-duty and use hose clamp bands made of high-strength 409 or 304 stainless steel. Heavy-duty sizes over 30″ contain an additional membrane layer of polyethylene and mastic, and utilize built-in ratchet straps.

    • Fits corrugated HDPE & HDPP pipe
    • Size: 6"
    • Compression Bands: 3 Hose Clamp Bands
    • Infiltration-proof exfiltration-resistant
    • Easily installed & immediately inspectable
    • Millions installed today with nearly a 100% success rate
    • Permanent protection with proven performance
    • Strong, shear & puncture-resistant

    SPECIFICATION

    PolySeal is manufactured with interval layers of our rubberized mastic, specially formulated to adhere aggressively to all known pipe surfaces. A sheet of puncture and shear-resistant woven polypropylene, and an outside backing of cross-laminated polyethylene makes PolySeal resistant to most acids and bases (additional protection available with Chemical Resistant PolySeal). The integrated compression bands mechanically “lock” into the corrugations of the pipe, bonding the mastic to the pipe wall, and forming a permanent seal.

    The minimum length of a PolySeal Coupler is the circumference of the outside diameter of the pipe, plus eight inches for overlap.

    INSTALLATION

    Surface preparations: Inspect the outside of the joint. Brush surface as needed to ensure it is free of debris. If installing on horizontal pipe, dig a bell hole for complete access to the joint.

    The coupler shall be placed around the pipe with the mastic side to the pipe wall and spanning the joint, while centered on the joint gap to be sealed. The protective film shall be removed and the coupler applied with the overlap at the top of the pipe. The tensioning straps shall be aligned between the pipe corrugations and tightened. The closing flap protective film shall be removed and the closing flap shall cover the exposed straps and the work area.
