The MarMac Polyseal Pipe Coupler offers soil-tight performance for any drainage pipe. Polyseal is a high-strength, reinforced coupler that delivers reliable soil-tight performance. It consists of thick rubberized bonding mastic that provides a tight positive seal around pipes and culverts.

The coupler incorporates a shear and puncture-resistant internal fabric with a chemical-resistant, cross-laminated polyethylene outer cover. Securing straps are engineered within the coupler to perform

as hose clamps, providing a seal against soil infiltration and ensuring that joints stay both soil-tight and flexible. ADS is one of the industry’s oldest suppliers of High Density Polyethylene (HDPE) and Polypropylene (PP) products and accessories, with close to fifty years of experience.
