SKU CH-HXJS-9M699

Flexible NBR/PVC elastomeric pipe insulation fits 1/2 in pipe, runs 6 ft with 3/4 in wall thickness and handles temperatures from -297 °F to 220 °F at R-5.0

  • Size1/2 in
  • Product typeTarps
  • Withstands extreme cold down to -297 °F
  • Handles high heat up to 220 °F
  • R-value 5.0 reduces thermal loss
  • NBR/PVC elastomeric foam resists moisture
  • Fits 1/2 in pipe with 3/4 in wall

Purpose and fit

This pipe insulation is designed for 1/2 inch piping and tubing with a 7/8 inch outer diameter. The unslit NBR/PVC elastomeric tube installs over copper, steel or plastic lines in mechanical and automotive systems. It suits installers who need a continuous 6 foot length with a 3/4 inch wall for thermal protection.

Sustained temperature performance

The material operates continuously from -297 Degrees F to 220 Degrees F without degradation. Its closed-cell structure maintains the rated R Value 5.0 across that range, resisting moisture ingress and thermal cycling in HVAC, refrigeration and process piping. The black elastomeric finish withstands UV exposure in outdoor runs.

Replaces thinner or damaged wrap

This product upgrades from thinner foam or fibre wrap that cannot meet the same R Value 5.0 or temperature span. The jump is worth it when condensation control, freeze protection or high-temperature stability are required on 1/2 inch lines. It does not suit applications needing pre-slit insulation or adhesive-sealed seams.

Questions about this item

How much heat does the 3/4 in wall insulation handle during continuous operation?

The NBR/PVC elastomeric material is rated for a continuous temperature range of -297 Degrees F to 220 Degrees F, so it remains stable during all-day exposure.

What pipe size must already be in place for the 1/2 in x 6 ft insulation to fit?

It is sized for a 1/2 in pipe with a 7/8 in outside diameter, matching the nominal 7/8 in ID of the insulation tube.

Will the R-5.0 rating of this unslit insulation change when used next to older pipe sections?

The approximate R-value of 5.0 is a property of the 3/4 in wall thickness itself and does not degrade when butted against existing insulated or bare pipe.
