Mar Mac Polyseal - Pipe Seal Coupler...
POLYSEAL PIPE COUPLERS
For assurance of permanent, flexible, soil and watertight joints
Polyseal was engineered as an external coupler for assurance against infiltration and exfiltration at the joint. Made with long-lasting, heavy-duty materials, Polyseal is an innovative design solution that creates a heavy-duty, positive watertight seal.


The pipe seal coupler incorporates high-strength, shear and puncture resistant internal reinforcing fabric with an impervious, chemical resistant cross-laminated polyethylene outer cover. Polyseal utilizes a specially formulated bonding mastic for polyethylene pipe along with high strength securing straps engineered within the coupler.

Polyseal is a permanent and proven coupler used in thousands of new installations as well as pipe repair.
