YUXI heat shrink cap offers an economical means of sealing the end of power cable with a completely watertight seal. Heat shrink cap is perfect for situations that call for extra protection against abrasion, moisture, chemicals and corrosion. The internal surface of the cap has a layer of spiral coated hot melt adhesive, which retains its flexible properties after recovery. It’s most commonly used to insulate and seal off wire and splice terminations in automotive, electrical and networking applications. Heat shrink cap is recommended for application both in open air and on underground power distribution cables with PVC, lead or XLPE sheaths. It is typically used in conjunction with heat shrink tubing.
