Material

Buna-N Rubber (nitrile) is a synthetic rubber that is compressible and resists oil, water, and mild chemicals.
Buna-N Rubber/PVC is a closed-cell, flexible foam that is resistant to impact, oils, and chemicals.
EPDM (ethylene propylene diene monomer) is a synthetic rubber that resists ozone exposure, UV light, chemicals, steam, and water.
Polyethylene is lightweight with good resistance to water vapor and heat gain in low-temperature applications.
Melamine is a lightweight, flexible foam that allows moisture and leaks to escape through its open-cell structure.
PIR Foam (polyisocyanurate) is a rigid foam insulation with high-heat resistance.
Fiberglass is a lightweight, workable material with good resistance to chemicals, heat, and corrosion.
Mineral Wool is a rigid material that is heat-resistant, workable, and easy to cut.
Fiberglass; Mineral Wool is a two-layer insulation that resists heat, chemicals, and corrosion.
Cotton is soft and easy to handle without the need for protective gear.
Cellular Glass is rigid with high compression strength and resistance to high temperatures and moisture.
Ceramic Fiber is a white, odorless material with high compression strength and resistance to extreme temperatures.

Insulation R Value

Insulation effectiveness is measured by an R-value based on the density and cell structure of the foam. The higher the R-value, the more effective the insulation.

Installation Style

The way in which the insulation closes around the pipe or tube.

Unslit indicates the insulation does not have an open seam for fitting onto the pipe or tube. It must be cut and glued, or slid onto the end of the pipe or tube.
Semi-Slit is partially slit to allow the insulation to be fully split by hand without the use of cutting tools.
Slit is factory slit without adhesive along the seam.
Slit with Adhesive is factory slit and comes with a pressure-sensitive adhesive along the seam for a secure fit around the pipe or tube.
Slit with Adhesive and Flap indicates the insulation tube is factory slit and comes with a pressure-sensitive adhesive overflap for securing the insulation around the pipe or tube.
Hinged has a pre-slit channel to allow the insulation to open wide and ease installation onto the pipe or tube.
Hinged with Self-Sealing Flap has a pre-slit channel to allow the insulation to open wide, ease installation onto the pipe or tube, and includes a pressure-sensitive adhesive flap for a secure fit.
Slit in Half indicates the preformed shapes are sold in halves and must be sealed and banded together around the tube or pipe.

Foam Cell Type

The cell structure of the foam insulation.

Open is lighter and more flexible than closed-cell foam. It allows moisture and leaks to escape preventing build up around the pipe or tube.
Closed is denser and more rigid than open-cell foam. It is durable and resists the passage of air and liquid.

Open
Closed

Plenum Rating

The insulation meets building codes that require all materials installed in an air-filled space to have fire and smoke-inhibiting qualities.

Plenum Rated

Flexibility

Rigid indicates the insulation does not bend or conform easily and is best used for straight runs of tube or pipe.
Flexible indicates the insulation bends and conforms to fit into tight spaces or to wrap around more intricate shapes.

Equipment, Tube & Pipe Insulation

Available1,467 products

Equipment, tube, and pipe insulation reduces heat loss or gain, prevents freezing, and controls condensation. These preformed shapes and sheets of insulation come in a range of materials with different resistance properties and benefits to fit the needs of the application. Removable insulation covers temporarily insulate pipe fittings, valves, and other components in a pipe system. Compressed-fiber rope-edge seals push into grooves, seams, and gaps in oven doors or furnaces to reduce thermal loss.
