Duravent 810003157 Fasnseal 4 in Ss 90 Degree Elbow

Product Description

The DURAVENT 810003157 is a FasNSeal 4-inch stainless steel 90-degree elbow fitting designed for direct vent and AL29-4C venting systems. Fabricated from AL29-4C grade stainless steel, this elbow provides a corrosion-resistant directional transition in gas appliance vent runs. It is rated for the high-condensate, high-temperature exhaust environment found in high-efficiency gas furnaces, boilers, and water heaters. HVAC technicians and plumbers install this fitting as part of a complete FasNSeal venting assembly where a 90-degree change in direction is required.

This elbow is suited for residential and light commercial venting applications where AL29-4C stainless steel vent systems are specified. It fits within the FasNSeal product family and is appropriate for use on high-efficiency Category IV gas appliances that produce acidic condensate in the flue. Typical installations include horizontal-to-vertical transitions and around-obstacle routing in mechanical rooms, utility spaces, and equipment closets.

Key Features

• 4-inch diameter fitting sized for standard FasNSeal vent runs
• 90-degree elbow geometry for right-angle directional changes in the vent system
• AL29-4C grade stainless steel construction resists acidic condensate corrosion
• Compatible with FasNSeal AL29-4C venting system components
• Weighs 9 pounds — substantial gauge construction for long-term reliability in service

Compatibility

Designed as an OEM-style component for FasNSeal AL29-4C stainless steel direct vent systems on Category IV high-efficiency gas appliances with 4-inch vent connections.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and applicable local mechanical codes. Shut down and lock out the gas appliance before disassembling any section of the vent system. All joints in an AL29-4C system must be secured and sealed per the FasNSeal assembly instructions to maintain flue-gas integrity. Do not mix components from different vent system families without confirming manufacturer-approved compatibility.
