>> Selection Guide
Confirm the outer diameter of your bundled cable harness and choose the matching tube spec.
Select temperature grade: 80℃ normal grade for general indoor use; 105℃ high temp grade for engine compartment or high-heat areas.
Choose zipper type if you need frequent inspection, closed type for fixed wiring.
Standard sizes are ready in stock, custom sizes for large quantity orders.
Q: What temperature grades are available for this PVC zipper sleeve?
A: We have two versions: normal type with 80℃ temperature resistance, and high-temperature type up to 105℃.
Q: Do I need to disconnect cables when installing zipper sleeve?
A: No. The zipper split design lets you wrap it over finished cables directly, convenient for later maintenance.
Q: Can you make custom sizes?
A: Yes, custom specifications are supported for bulk production orders. Stock sizes Φ20~Φ50 can be shipped quickly.
Q: What is the main advantage compared with heat shrink tube?
A: It does not require heat gun, reusable, perfect for projects that need repeated opening and inspection.
Q: Is it waterproof?
A: It features water repellent performance for general indoor & sheltered outdoor use, not for continuous submerged application.
