10 PCS Bike Brake Bleeder Rubber Cap Bleed Screw Dust Cover Nipple Fitting Cap for Mountain Bicycle Road Bicycle MTB Hydraulic Disc Brake

Works perfect

These replacement dust covers work great on my Shimano XT disc brake set. The dust covers that came with the brakes were cracked and quickly broke off. These dust covers were very easy to install as they snapped on without issue and fit perfectly. This 10-piece kit is great to keep in my drawer in case this happens again.

Had to replace my missing "bleed nipple cap" (part # Y8B214000) for my SHIMANO ULTEGRA Hydraulic Disc Brake Front Caliper R8000 Series. This product does the job well, though the fit is not perfect; there's a slight gap compared to the OEM part. Worth mentioning, the OEM version includes only one cap, whereas this vendor provides 10 rubber caps at a reasonable price.

These fit Shimano 105 well. I needed one, bought the set of 10. I now have 9 spares. My six years old OEM Shimano cap was missing. This fixes that. Not too tight. Not too loose.

They as expected. Used on a Shimano BR-RS505

I ordered these to replace the original Shimano crud covers. The original caps were still good, but the keeper straps were broken. These replacement caps work, but are much smaller, and a bit more difficult to pop on. The longevity of this product will remain to be seen.

They are a tight fit, but do the job,

Worked without a problem, seems to be equivalent to OEM bleeder nipples on my rear XTR brake. Already survived many mountain bike rides. What you get is great; however, the price seems to be too high but I could not find an alternative. Gave some to my son.
