Description for Bell & Gossett 108121

Copper Red Ring Monoflo Fittings let you use a single pipe to serve as both supply and return main.


  • Connect risers to the main, assuring proper division of water to each heating unit regardless of type and its position in the system
  • Recommended for most installations including cast iron non-ferrous baseboards, free-standing radiation or convectors
  • Only one fitting is needed for most installations for adequate diversion for upfeed radiation. For most applications, a second fitting can be used if higher resistance is required.

Worked well for adding in floor radiant

        Comments about 3/4" x 1/2" Copper Red Ring Monoflo Tee:

        I wanted to add under floor radiant heat in our master bath using the Ultra-Fin system. The entire master bedroom bath was on one zone. I used two 3/4" x 1/2" monoflo fittings(one supply fitting and one return fitting) on the bedroom/bath zone to push water through the under floor 1/2" pex loop with no problem getting enough flow to purge air in the system despite being told it would not work. The under floor pex loop was 95' long with plenty of flow using two monoflo fittings.
