Good quality, tight tolerance

Very well made. Just note that the fit is quite tight, so you might need a press tool to install them properly.

Perfect fit for my project

These sleeves are exactly what I needed for my machinery repair. The 4mm ID fits snugly and the stainless steel quality is excellent.

Durable and smooth

The surface finish is incredibly smooth. No burrs or rough edges. Great for reducing friction in my assembly.

Ordered wrong size

The product itself seems fine, but I ordered the 5mm OD by mistake. Make sure to check your measurements twice.
