YRS series heat shrink tubing is a single-wall or dual-wall cross-linked polyolefin product designed specifically for automotive fuel line and wire harness applications. The outer layer provides abrasion resistance and fluid barrier properties; an optional adhesive inner layer creates a waterproof seal at cable exits and connector transitions.

YRS tubing slides over nylon or PVF fuel lines and shrinks to form a smooth, oil-resistant outer jacket. Verified by 72-hour fuel and brake fluid immersion tests.
Seals against splash exposure to fuel, oil, and road grime at connector transitions and harness branches. Optional adhesive lining keeps moisture out of splices.
Physical barrier over orange HV cable jacketing at grommet passes and bend points. Custom colors support high-voltage identification schemes.
