Parts Desk Insights
Best Use Case: Ideal for protecting and sealing marine electrical splices/connection areas where you want both insulation and an adhesive-lined environmental seal to help resist corrosion and abrasion.
Common Issues: To get the best seal, ensure the tubing is sized correctly for the connection/joint and the underlying surfaces are clean and properly prepared before shrinking. If the tubing isn’t fully heated and seated, the adhesive seal may not fully form.
