FOR IMMEDIATE RELEASE<\/strong>
\nPRODUCT ANNOUNCEMENT<\/strong>
\nPolywater announces UL approval for conduit mechanical sealant line in the U.S.<\/strong>
\n(Stillwater, MN June 24, 2020)<\/strong> \u2014 Polywater announces that its Polywater | Hauff-Technik mechanical
\nseals have been certified by Underwriters Laboratories (UL) to meet the requirements of Outlet
\nBushings and Fittings (QCRV). The PHRD seals are considered watertight and approved for use under
\nNEC articles 230.8 and 300.5 (G), which govern the sealing of raceways entering a building or
\nstructure.<\/p>\n

Polywater | Hauff-Technik PHRD conduit seals are the most diverse mechanical seals on the market.
\nThey can be designed to seal around any size and configuration of cables or pipes and can be
\nmanufactured for core-drilled holes or conduits with diameters of 1.5 inches to several feet. EPDM
\nrubber was used for the seals tested by UL, but additional rubbers are available for other applications.
\nThe PHRD mechanical seals are suitable for use in Class 1 Division 2 hazardous locations as defined
\nby NEC.<\/p>\n

The innovative one-piece, split design provides a simple, labor-saving sealing solution for cables or
\npipes that are already laid or newly laid. Stainless steel pressure plates and bolts provide durability in
\ncorrosive environments and are rodent resistant. Reliability, labor saving, and durability are criteria
\nengineers and contractors demand when sourcing mechanical seals.<\/p>\n

“We are pleased to obtain this certification. The UL mark represents rigorous testing that assures both
\nthe quality and safety of our product.”, says Sheri Dahlke, technical director. “This gives our end users
\nthe confidence of a third-party certification. Providing airtight and watertight seals for these industries is
\ncritical to engineers\u2019 needs for reliability while meeting industry guidelines,\u201d according to Dahlke.
\nPolywater, a leading specialty chemical manufacturer for the electrical and telecommunications
\nindustries based in Stillwater, MN, collaborates with Hauff-Technik Gmbh & Co. KG, based in
\nHermaringen, to provide the Polywater | Hauff-Technik line of sealing systems to the U.S. market.<\/p>\n
