SBRS-125G(2X)(3X)(4X)                                       
 
Environmentally Friendly Adhesive lined Dual Wall Heat Shrink Tubing
 
Description
 
  SBRS-125G(2X) (3X) (4X)is a cross-linked polyolefin tube that is extruded with an inner layer of adhesive. The inner layer of adhesive, with superior sealing capability, is also a buffer against mechanical strain. Dual wall heat shrink tubing is designed to provide superior sealing against water, corrosive gas and chemicals. Typical applications include environmental sealing of in-line splices, sealing and strain relief of connectors and terminals, abrasion protection and electrical insulation of automotive wiring harness splices and valuable components, fleet & marine sealing & protection and wire bundling etc.
