Parts Desk Insights
Best Use Case: Use this adhesive-lined 3:1 tubing on marine wiring joints where you want a tighter shrink and an insulated, sealed finish that helps guard against moisture-related corrosion.
Common Issues: For best results, ensure the tubing diameter before shrinking matches the splice/termination size you’re covering and that the adhesive has a clear path to spread evenly during heating. If the tubing doesn’t fully seat or the sealant doesn’t appear to form a continuous barrier, confirm you’ve used the correct tubing size and apply heat uniformly.
