Protech Special Gas Vent System

Each vent length and component features a built-in mechanical locking band and gasket. Parts are simply pushed together to a stop bead, which renders the joints air and water-tight. By tightening their integrated mechanical locking band, parts are fastened together in seconds. FasNSeal® can be taken apart and reassembled in minutes, making inspection, maintenance or rerouting of FasNSeal® systems a breeze. Should a part or gasket ever become damaged, replacement takes less than five minutes and the integrity of the system is not compromised!

FasNSeal® is manufactured from AL29-4C®, a superferritic stainless steel designed for extreme resistance to chloride ion pitting, crevice corrosion and stress corrosion cracking, as well as general corrosion in oxidizing and moderately reducing environments. AL29-4C® is an ideal choice for resisting deleterious effects of corrosive condensates created by partially or fully condensing natural gas and propane fired heating appliances. The Canadian Gas Research Institute found that test results proved AL29-4C® to be one of two “most corrosion resistant alloys of twenty candidate stainless steels evaluated for resistance to chloride-induced corrosion in condensing and partially condensing gas-fired appliances”.
