Polywater: Innovative Conduit Seals

Polywater chemical and mechanical seals exceed NEC codes regarding sealing conduit raceway systems. Superior to duct putty. The sealants stop water, gases, and rodents from causing outages.

Polywater | Hauff-Technik mechanical PHRD seals are made of stainless steel and EPDM rubber to handle the harshest environments. They have a unique split design so that you can easily install them around existing cables, and pipes. They are ideal for all types of cables, bus bar, enclosure and building entrance environments with post installation movement, vibration, high water pressure, gases or if negative pressure must be maintained. The PHRD offers an optimal solution for sealing conduits to meet NEC and NESC building entry regulations.

Polywater FST 2 - part, closed-cell, duct sealant provides superior performance to duct putty and hardware store purchased foams. FST Duct Sealant cartridges can seal multiple conduits and once cured stops 22 feet of water head pressure indefinitely. FST is stronger, more chemically resistant, and cures 50 times faster than open-cell aerosol foams. The FST seal has excellent adhesion to PVC, rigid steel, EMT, IMC, fiberglass, and polyethylene conduits. It stops methane and other gases to keep electrical systems intact.  FST is a proven solution that has been used for years to protect switchgear, panels, riser poles, combiner boxes, meters, and all types of electrical and telecommunication apparatus. It creates a semi-permanent seal and is re-enterable.

AFT 2 – part, closed-cell, foam sealant provides 10 feet of water-blocking in electrical and communication ducts. AFT shows excellent adhesion to a variety of conduits. AFT seals conduit faster and with better performance than duct putty or one-part insulating foams.  The two-part aerosol foam expands to fill any size void. The AFT aerosol spray package comes with multiple actuators, which allow the sealing of multiple ducts.
