PGKD vs. Competitors:
Polywater│Hauff Technik PGKD Modular Seal | Competitive Products | |
|---|---|---|
Cost | $$ | $ |
Materials | 316 Stainless Steel for durability even in corrosive environments | Galvanized Steel is prone to corrosion in specific area. |
Ease of Use | Nuts are molded directly into the pressure plate, no loose parts to lose | Bolts and nuts are loose and can easily be lost. |
Labor Saving | Retightening of bolts is not recommended | Retightening of bolts within 24 hours is recommended; more labor time. |
Watertight | Bolts are only threaded halfway down the bolt so tracking of water through the seal can't happen | Bolts are threaded end to end which can cause a tracking path for water to follow through the seal |
Water Head Pressure | Holds up to 72.5 PSI | Only holds up to 20 PSI |
Warranty | 10 year | ? |
Proper Torque Indicator | Most importantly – a patented indicator is incorporated into the seal. When the seal is torqued properly, the windows in the pressure plates change to yellow; a visual indicator that the seal is installed correctly without requiring a torque wrench. The most asked question from field crews is, “Did I install it correctly?” Now they know! | Must use a torque wrench and it is recommended to retighten 24 hours later to ensure proper sealing. More labor time and guess work installing this system |
