Industrial Valve Insulation Jacket

This removable jacket fits strainers, tees, valves and wyes with circumferences between 42 and 49 inches. Silicone-coated fiberglass cloth covers a fiberglass and mineral wool core three inches thick. Quick-release fabric flaps and wire twists secure the cover for fast installation and removal during maintenance cycles.

Suited for high-temperature piping up to 900

The R-value of 0.48 provides thermal protection for universal valve types in industrial settings. Buyers needing insulation for smaller fittings or lower temperature limits should look at alternative cover sizes. The gray jacket ships flat at 54 inches long by 18 inches wide for on-site fitting.

Sustained heat exposure up to 900 degrees Fahrenheit

The fiberglass and mineral wool core maintains its structure during continuous service at the rated maximum temperature. Silicone coating resists degradation from prolonged thermal cycling. Quick-release fasteners allow repeated access without damaging the insulation jacket during routine inspections.
