90° Elastomeric Elbow Fitting for 3 1/8 in Tubes

This Nomaco Kflex elbow fitting insulates 90-degree pipe bends on ducts, tanks and piping. It suits installers working with 3 1/8 inch tube sizes who need thermal protection from -297 to 220 degrees F. The NBR/PVC elastomeric body delivers an approximate R-value of 4.6. Buyers needing straight-run insulation or fittings for other diameters should look elsewhere.

Check Tube Size and Bend Radius Before Ordering

Verify that the pipe carries a 3 inch inner diameter so the 3 1/8 inch nominal insulation bore fits correctly. Confirm the bend is a true 90-degree elbow and that the 1 1/8 inch length and 4 1/8 inch width clear surrounding components. The fitting is restricted from sale in certain states; check local regulations before purchase.

Black NBR/PVC Material and Temperature Range

The black elastomeric construction resists temperatures from -297 up to 220 degrees F without additional coatings. Its closed-cell structure provides the stated R-value 4.6 thermal barrier in a single piece. No separate adhesives, tapes or fastening hardware are included with the fitting.

Questions about this item

Does the Kflex 801-LRE-048318 elbow come with adhesive or tape, or must I buy those separately?

The fitting is a pre-formed NBR/PVC elastomeric piece only; adhesive, tape or vapour-barrier jacketing are not included and must be purchased separately.

Should I choose this 90° elbow for a 3-1/8 inch tube or look for a different size?

This model is made for a 3-1/8 inch nominal tube I.D. with a 1/2 inch wall; select it only when those exact dimensions match your pipe.

What does the R-4.6 rating mean once the elbow is installed on a chilled-water line?

At 1/2 inch thickness the insulation provides approximately R-4.6, reducing heat gain on lines operating anywhere from -297 °F up to 220 °F.
