Heat-fab Inc. has introduced the Saf-T Vent EZ Seal gas vent for residential applications. Featuring a built-in high temperature gas and moisture seal and the Heat-fab ring and tab closure system, the gas vent requires no RTV sealant, simplifying installation and enabling immediate use of the system without any curing or break-in period. Saf-T Vent EZ Seal has a factory-adhered seal to ensure proper seating for a secure fit. The fixed-in-place seal prevents rolling, slipping or tearing during assembly. The vent is manufactured of AL 29-4C, Allegheny Ludlum's corrosion resistant stainless steel. www.heat-fab.comHeat-fab, Inc.
