OVERVIEW
Genuine VW/Audi hose clamp, part number N-102-018-01. This original band clamp secures a hose at the connection that specifies this part number. The fitment table identifies confirmed brake-booster vacuum-hose applications and preserves the brake-system supplier restrictions.
Technical details
- Original part number: N-102-018-01 / N10201801.
- Published nominal clamp size: 21 x 7 x 0.6 mm.
- Band-style hose clamp as shown in the original product image.
- One clamp is supplied. Hose, fitting, brake booster and other connection components are separate.
- Confirm the original clamp number, hose connection and component configuration before installation.
This hardware retains the specified hose connection. Correct sizing and installation matter: an arbitrary clamp can fit poorly, damage the hose or fail to retain it properly. The listed dimensions are nominal part specifications, not a recommendation to fit any hose of a similar apparent diameter.
Common reasons to replace
Replace a missing clamp or one with a distorted band, damaged closing features, excessive corrosion or a loss of proper retention. Renew it when the factory hose-service procedure requires replacement after removal.
Inspect the hose and fitting together with the clamp. A cracked, hardened or incorrectly seated vacuum hose can continue to leak after a clamp is replaced. A damaged fitting or faulty check valve also requires its own repair.
A vacuum leak can affect brake-assist operation, but a change in pedal effort is a diagnostic symptom rather than proof that this clamp is at fault. Check the complete vacuum supply, hose connections, check valves and booster as directed by the factory diagnostic procedure.
Installation and service notes
Identify the brake-system configuration and exact hose connection before ordering. The ATE and Girling-TRW notes below apply to the stated profiles; they should not be generalized to every brake assembly on the same model.
Follow the factory procedure for removing and installing the clamp. Use the specified tool and place the clamp at the prescribed position on the correctly seated hose. Avoid crushing or cutting the hose, and do not substitute a screw-type clamp without support from the repair instructions.
Keep dirt out of the open connection and inspect the hose sealing area and fitting before assembly. Replace damaged connection components rather than attempting to compensate by excessively tightening hardware.
After repair, complete the required vacuum-leak and brake-assist checks before driving. If pedal effort or assist remains abnormal, continue diagnosis of the complete system. This listing contains only the clamp, not a complete brake-vacuum repair kit.
