Sealants & Lubricants for Z-Vent Pipe.
Z-Flex lubricant is recommended for assembly of Z-Vent pipe, fittings and other components to ensure a smooth fit without damaging the silicone gasket.
Z-Flex sealant is intended for use on Z-Vent components which are exposed to outdoors - rain caps, termination hoods, etc. - to minimize moisture and rainwater penetration.
