DuraVent FasNSeal Male to Female Jeremias Muffler: a 7 inch part specified by name
The DuraVent FasNSeal Male to Female Jeremias Muffler is a 7 inch vent part to order when your system design calls for it by name. It is the counterpart to the female to male version. “Male” means the narrower pipe end, while “female” means the wider end it slides into. DuraVent does not describe this muffler’s function or location in the vent run. 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.
The vent run uses FasNSeal parts all the way from the appliance’s exhaust outlet to the outdoors. DuraVent says not to mix another maker’s pipe, fittings, or joining methods into that run because the joints and seals differ. FasNSeal serves natural gas or propane appliances that call for a special gas vent. The appliance maker’s instructions determine whether the vent exits through a wall or roof and how long it can be.

The DuraVent FasNSeal Male to Female Jeremias Muffler ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
