Pipe Insulation Elbow 90°

This Nomaco Kflex elbow fitting insulates 2-inch pipe with a 90-degree turn. It uses Buna-N rubber and PVC material rated for temperatures from -297 to 220 degrees Fahrenheit. The closed-cell foam provides an R-value of 4.9 and carries a flame spread index of 25. It is plenum rated and offers antimicrobial, fire-retardant protection.

Replaces Damaged Or Missing Insulation

Use this elbow when existing pipe insulation is torn, wet or missing at a bend. The jump is worth it when you need continuous thermal protection and condensation control on a 2-3/8-inch outside diameter tube. It suits systems requiring plenum-rated material with a 3/4-inch wall thickness. Buyers who need straight-run insulation or a different pipe diameter cannot use this specific form.

Unslit Design Requires Slide-On Installation

The unslit style means you must slide the fitting over the pipe end before the joint is made. This works best during new assembly or when the pipe can be disconnected. Forcing it onto an installed pipe risks tearing the closed-cell foam. No adhesive or tape is included, so secure the seams separately. Installers without pipe access will find this fitting impractical.
