DuraVent FasNSeal Female to Male Jeremias Muffler: a 7 inch part specified by name
The DuraVent FasNSeal Female to Male Jeremias Muffler is a 7 inch vent part sold under that name. It is one of a pair, with the companion part named male to female instead. Choose this part when the vent system design specifically names it, not just because the size matches. Female means the wider pipe end. Male means the narrower end that slides into it. FasNSeal is DuraVent’s stainless steel vent for high efficiency gas boilers, furnaces, and water heaters, built to carry pressurized exhaust and its acidic condensate outside.
Each FasNSeal part has a gasket and a locking band built into its wider end to seal and hold the connection. The overlap at each joint takes up 2 inches, which matters when planning the vent layout. Need the ends the other way around? See the DuraVent FasNSeal Male to Female Jeremias Muffler. The DuraVent FasNSeal Female to Male Jeremias Muffler ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
