FOR IMMEDIATE RELEASE PRODUCT ANNOUNCEMENT
Polywater announces UL approval for conduit mechanical sealant line in the U.S.
(Stillwater, MN June 24, 2020) — Polywater announces that its Polywater | Hauff-Technik mechanical seals have been certified by Underwriters Laboratories (UL) to meet the requirements of Outlet Bushings and Fittings (QCRV). The PHRD seals are considered watertight and approved for use under NEC articles 230.8 and 300.5 (G), which govern the sealing of raceways entering a building or structure.
Polywater | Hauff-Technik PHRD conduit seals are the most diverse mechanical seals on the market. They can be designed to seal around any size and configuration of cables or pipes and can be manufactured for core-drilled holes or conduits with diameters of 1.5 inches to several feet. EPDM rubber was used for the seals tested by UL, but additional rubbers are available for other applications. The PHRD mechanical seals are suitable for use in Class 1 Division 2 hazardous locations as defined by NEC.
The innovative one-piece, split design provides a simple, labor-saving sealing solution for cables or pipes that are already laid or newly laid. Stainless steel pressure plates and bolts provide durability in corrosive environments and are rodent resistant. Reliability, labor saving, and durability are criteria engineers and contractors demand when sourcing mechanical seals.
"We are pleased to obtain this certification. The UL mark represents rigorous testing that assures both the quality and safety of our product.", says Sheri Dahlke, technical director. "This gives our end users the confidence of a third-party certification. Providing airtight and watertight seals for these industries is critical to engineers’ needs for reliability while meeting industry guidelines,” according to Dahlke.
Polywater, a leading specialty chemical manufacturer for the electrical and telecommunications industries based in Stillwater, MN, collaborates with Hauff-Technik Gmbh & Co. KG, based in Hermaringen, to provide the Polywater | Hauff-Technik line of sealing systems to the U.S. market.
