Nomaco Kflex

Nomaco Kflex 801-LRE-068258 2-5/8" x 59/64" Elastomeric Elbow Pipe Fitting Trap

SKU CH-DTQ5-YYBBA MPN 801-LRE-068258

Elastomeric elbow pipe fitting provides thermal insulation with a 3.2 R-value and antimicrobial, flame-retardant properties from -297 to 220 degrees F

  • Product typeDrain Components
  • Product colorBlack
  • Resists microbial growth with antimicrobial elastomeric material
  • Withstands extreme cold down to -297 °F operating temperature
  • Handles high heat up to 220 °F maximum operating temperature
  • Meets plenum fire safety with flame spread index 25
  • Provides thermal efficiency through 3.2 R-value insulation

Pipe Fitting Insulation Elbow

This Nomaco Kflex elbow fitting is designed for pipe insulation applications. The 90-degree form suits directional changes in piping systems. Installers working with 2-5/8 inch outside diameter tubing will find this component compatible. The unslit installation style requires manual fitting during assembly.

Thermal Performance Range

The insulation operates continuously between -297 degrees F and 220 degrees F. Its closed-cell foam structure delivers an R-value of 3.2 for thermal resistance. The material maintains flexibility across this temperature span without cracking. Antimicrobial properties resist microbial growth on the insulation surface.

Build And Safety Features

The NBR/PVC based elastomeric construction provides flame-retardant performance with a flame spread index of 25. Plenum rating allows installation in air-handling spaces per building codes. The black finish identifies the material in concealed locations. Buyers needing straight-run insulation or different diameters will require separate components.

Questions about this item

How does the 3.2 R-value affect heat retention when the fitting runs continuously?

The 3.2 R-value provides consistent thermal resistance, reducing heat loss or gain through the elbow during all-day operation.

What pipe size must I already have for this 2 5/8-inch inside diameter elbow to fit?

This elbow fits tube with a 2 5/8-inch outside diameter; ensure your existing pipe matches that dimension.

Will the NBR/PVC elastomeric material stay flexible next to older metal pipework at low temperatures?

The material remains flexible down to -297 °F, so it will not stiffen or crack alongside older metal pipes in cold conditions.
