Plumbing Insulation

Plumbing insulation includes elastomeric materials made to insulate refrigerant lines, cold-water and chilled-water piping, hot-water piping, and roof drains. Available in tubular, self-sealing, sheet, and roll formats, these products help retard heat flow, limit heat gain or heat loss where applicable, and help reduce condensation or frost formation on cold surfaces.

Plumbing Insulation Buying Guide

Choose insulation by the surface you need to cover, then match the listed dimensions and installation format to the application. The available selection includes tubular insulation for compatible pipe and line sizes, pre-slit self-sealing tubes for pipe runs, and flexible sheets or rolls for larger or irregular surfaces.

Use Cases

Insulate pipe runs and mechanical surfaces

Tubular products are designed for compatible refrigerant lines, cold-water piping, chilled-water systems, and, on select products, hot-water piping. Flexible sheets and rolls are intended for equipment, ducts, tanks, vessels, and large-diameter pipes.

How to Choose

Match format, ID, wall, and coverage

For pipe insulation, select a tube with the required nominal inside diameter and wall thickness. For broad or irregular surfaces, compare sheet or roll dimensions. Also account for stated minimum order quantities.

Applications

Support cold- and hot-system insulation needs

Several elastomeric options help reduce condensation or frost formation on cold piping and surfaces. Select sheet and roll products also help deter heat gain on cold systems and retard heat loss on hot equipment, ducts, and large pipes.

Additional Information

Compare construction and installation details

Available features include nonporous, nonfibrous, closed-cell, mold-resistant, and UV-resistant constructions. Self-sealing tubes have factory-applied adhesive and release liners, while pre-slit designs open around compatible pipe runs.

6 ftCommon tube length

The listed pipe insulation tubes and self-sealing tubes are 6 feet long.

3/8–1 in.Listed tube wall range

Available tubular wall thicknesses range from 3/8 inch to 1 inch.

3/8–4-1/8 in.Listed nominal ID range

Tube options span nominal inside diameters from 3/8 inch through 4-1/8 inches.

36–48 in.Sheet and roll widths

Flexible sheet and roll formats are listed in 36-inch and 48-inch widths.

Planning Guide

Plan the right fit before choosing

Start With the Surface

Choose a tube, self-sealing tube, sheet, or roll

The product format should suit the installation area. Standard elastomeric pipe tubes are sized for compatible piping. Self-sealing closed-cell tubes are pre-slit and close with an adhesive seam. Flexible sheets and rolls conform to larger or non-round surfaces.

  • Use pipe tubes for compatible refrigerant, cold-water, chilled-water, or applicable hot-water lines.
  • Choose self-sealing, pre-slit tubing for compatible pipe runs where a factory-applied adhesive seam is preferred.
  • Use flexible sheets or rolls on equipment, ducts, tanks, vessels, and large-diameter pipes.
Confirm Dimensions

Compare inside diameter, wall thickness, and material coverage

Tubular insulation is offered in 6-foot lengths with listed nominal inside diameters and wall thicknesses. Sheets and rolls list their thickness, width, and length, helping buyers compare coverage for large insulation work.

  • Available tube nominal IDs include 3/8 inch, 1-3/8 inch, 1-5/8 inch, 2-1/8 inch, 2-5/8 inch, 2-7/8 inch, 3-1/8 inch, and 4-1/8 inch.
  • Listed tube wall thicknesses include 3/8 inch, 1/2 inch, 3/4 inch, and 1 inch.
  • Sheet and roll choices include 3/8-inch and 1/2-inch thicknesses with different widths and lengths.
Plan for the Installation

Review moisture-control, UV, and order requirements

For cold applications, compare products described as helping reduce condensation or frost formation. Several tube products offer moderate UV resistance or a UV-resistant blend. Minimum orders vary by item and should be reviewed before purchasing.

  • Nonporous, nonfibrous, closed-cell, and mold-resistant features are available on select products.
  • Some products support moderate UV exposure without an added protective coating.
  • Listed effective minimum orders range from 1 selling unit to 38 units, depending on the item.
FAQ

Common questions before buying

What plumbing insulation formats are available?

The selection includes elastomeric pipe insulation tubes, self-sealing closed-cell pipe insulation tubes, flexible sheets, and flexible rolls.

How do I select pipe insulation tube size?

Match the product's listed nominal inside diameter to the compatible pipe or line size, then compare the listed wall thickness.

When should I choose self-sealing pipe insulation?

Choose a self-sealing, pre-slit tube when insulating compatible pipe runs and a factory-applied adhesive seam with release liners is preferred.

Can flexible elastomeric insulation be used beyond pipe runs?

Yes. The listed sheets and rolls are designed for equipment, ducts, tanks, vessels, and large-diameter pipes.
