Quick-Connect Fiberglass Pipe Insulation
Slit Straights
 |
Wrap around short lengths of straight pipe, such as unions, connectors, reducers, and adapters. Then press the straps down for a tight, reliable seal.

Tapered Heat-Shrink Tubing
 |  |  |
Style A (After Shrinking) | Style B (After Shrinking) | Style C (After Shrinking) |
A different shrink ratio on each end allows this tubing to fit over cable assemblies and wire harnesses with large connections, or around connectors with a 90° elbow. An adhesive lining melts when the tubing is heated and bonds to the underlying surface, creating a water-resistant seal. The tubing length listed is after shrinking; the length before shrinking is 20-25% shorter.
Lipped End—Lipped-end tubing has a ridge on the inside of one opening for better retention than nonlipped-end tubing. It’s often used with grooved adapters—upon shrinking, the lip grips onto the groove.
Dielectric Strength—Dielectric strength is the maximum voltage a material can handle before it starts to breakdown. The higher the dielectric strength of a material, the better it is for preventing electricity, heat, or signal from dissipating from wire and cable.
