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: 60"
Compression Bands: 3 Built-In Ratchet Straps
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.
