OVERVIEW

Original small-diameter hose clamp

The N-024-528-1 Genuine VW/Audi hose clamp retains a small hose over its matching connection at the original position specified in the parts diagram. The archive photo shows a screw-adjusted metal band clamp. Match the original clamp specification, hose outside diameter and fitting before ordering; a vehicle can use many different clamp sizes and designs.

Technical details

  • Original number: N-024-528-1 / N0245281.
  • Genuine catalog size: 8–12 mm hose clamp range.
  • Archive design shown: screw-adjusted metal band with an external screw housing.
  • Application: original small hose connection requiring this exact clamp number.
  • Quantity: one clamp. Hose, pipe, valve and other connections are separate.

Clamp range refers to the diameter around the outside of the hose at the connection. It is different from the hose's internal bore size. The classic fuel-hose applications reference a 5 mm hose bore; confirm the actual hose outside diameter and original fitting rather than selecting a clamp solely from the internal hose size.

Common reasons to replace

  • Damaged screw mechanism: damaged drive engagement or adjustment threads can prevent controlled clamping.
  • Deformed band: a distorted clamp may not seat evenly around the hose.
  • Corrosion: deterioration can make adjustment difficult or compromise the retaining hardware.
  • Missing or incorrect clamp: restore the specified original connection after previous hose work.
  • Hose replacement: inspect and renew the clamp when the original hose or fitting is serviced.

A leaking or loose connection requires inspection of the hose and fitting as well as the clamp. New hardware cannot repair a cracked hose, damaged nipple or mismatched hose diameter. Replace damaged connection components and use the original clamping arrangement appropriate to the serviced circuit.

Installation and ordering guidance

Confirm the vehicle identification number and original hose connection diagram. The table identifies restricted catalog applications for this original clamp number. It does not imply that every hose on a listed vehicle uses an 8–12 mm clamp.

Follow the service procedure for the affected circuit before disconnecting the hose. Inspect the hose end and fitting, position the hose at the required engagement depth and place the clamp at the specified retention area. Tighten according to the prescribed connection procedure and avoid overtightening, which can damage the hose or fitting.

Use the correct clamp design if the original connection requires a particular retention arrangement. After service, perform the applicable leak and functional checks for that circuit and confirm that the hose is securely seated. Count the clamps required at both ends of the serviced hose and order the necessary quantity.
