Tube - ID 4.0mm
$7.99
Product details
This replacement tube has a 4.0mm inner diameter and serves as a flexible line inside the vacuum. It routes air or fluid between components along its run.
Over time, small-bore tubing hardens, cracks, or kinks, which restricts flow through the line and can break the connection at either end. A pinched or split tube leads to weak or lost transfer along that path. Fresh tubing of the correct inner diameter restores a clean, unobstructed run.
- Part: tube with 4.0mm inner diameter.
- Function: routes air or fluid between components.
- Benefit: restored, leak-free flow.
- Tip: trim to match the length of the line you are replacing.
Slide the tube onto the fittings and confirm a snug fit at both ends. Measure your existing line's inner diameter before ordering to confirm the match.
