Sized for 2-5\/8 inch outside diameter pipe with a 1\/2 inch wall thickness, this 6-foot section features a factory-applied lap seal adhesive strip that creates a secure, tool-free seam closure. Rated for an R-value of 3.2, it limits heat gain and energy loss on chilled water, refrigerant, and domestic cold water lines. The operating temperature range spans -297 degrees F to 220 degrees F, covering most HVAC and plumbing service conditions. Licensed HVAC technicians and plumbers are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insulation sleeve fits 2-1\/2 inch nominal pipe, corresponding to a 2-5\/8 inch outside diameter. It is used in residential and commercial mechanical systems where condensation control is critical, including chilled water distribution, refrigerant suction lines, and cold domestic water piping. The black finish is suitable for exposed indoor mechanical room installations. The flexible lap seal construction improves seam integrity compared to butt-edge designs, reducing the risk of moisture infiltration, mold development, and thermal bridging at the joint.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlexible lap seal adhesive strip provides a secure, consistent seam without additional adhesive at the joint\u003c\/li\u003e\n  \u003cli\u003eR-value of 3.2 limits heat gain and condensation on chilled and cold-water piping\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range of -297 degrees F to 220 degrees F suits both refrigeration and hot-side applications\u003c\/li\u003e\n  \u003cli\u003eWater absorption below 0.20 percent by volume resists moisture ingress and inhibits mold growth\u003c\/li\u003e\n  \u003cli\u003eGood ozone resistance extends service life in mechanical rooms with ozone-generating equipment nearby\u003c\/li\u003e\n  \u003cli\u003e6-foot length per section reduces the number of field joints on straight pipe runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit 2-1\/2 inch nominal pipe with a 2-5\/8 inch outside diameter. Suitable as an OEM-style or field-applied insulation sleeve on copper, steel, CPVC, and PEX piping in HVAC and plumbing applications where the specified wall thickness and temperature range are appropriate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or plumbers as part of new construction or retrofit insulation work. Isolate and depressurize the pipe and allow it to reach ambient temperature before applying the sleeve. Slide the sleeve over the pipe or slit and wrap it around in-place piping, then press the lap seal firmly along the full length of the seam. For end joints and fittings, use a compatible elastomeric insulation adhesive to seal butted edges and prevent moisture infiltration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe O.D.
