Product Details

The Sterling 091-3090 is a 3-inch stainless steel 90-degree elbow designed for Category III venting applications with Sterling gas-fired unit heaters. This UL1738-approved vent pipe fitting allows for directional changes in exhaust vent runs, enabling installation at 90-degree angles or vertical configurations within the venting system.

Key Features:

  • 3-inch diameter stainless steel construction for corrosion resistance
  • UL1738 approved for Category II, III, and IV venting applications
  • Features patented built-in mechanical locking band for secure connections
  • Triple-lipped directional gaskets provide reliable sealing
  • Smooth, clean welds positioned 90° from mechanical locking bands
  • Fixed 90-degree angle for consistent directional changes

This elbow fitting is engineered for use with positive vent pressure systems created by exhaust blowers in Sterling unit heaters. The stainless steel construction meets the stringent requirements for Category III venting, which demands corrosion-resistant materials capable of handling condensing flue gases under positive pressure conditions.

Great buy and fast shipping very happy.

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.
