introduced the revolutionary SealLock coupler, an industry
was transformed. ®
was the first to introduce an all plastic duct coupler with
many added benefits that addressed problematic issues that
the industry had faced for a longtime.
The SealLock coupler is manufactured from a proprietary
high modulus polymer that provides a durable, corrosion resistant
connection under the most severe conditions. The low profile
allows the SealLock to pass through plow chutes unhindered
and it's high pull strength ensure an intact joint.
This reverse threaded coupler can be installed by two methods,
Pressing or Threading. Pressing is preferred
because the duct is forced hydraulically to the Posi-Stop
providing consistency of installation.
SealLock coupler provides an air and water tight seal.
In cases where the duct is undersized or oval shaped, the
optional o-ring seals are recommended.
