Customer Reviews (4.6 / 5 · 5 reviews)

David R. ★★★★★

Installed one on my fuel return line and it crushed evenly without cracking. No leaks so far, and the 10-pack gives me plenty of spares for future projects.

Eva ★★★★★

Perfect seal on my brake line connections with zero leaks after tightening. The aluminum crushes just enough to conform without over-compressing, and having ten in the pack means spares for the next project.

Sebastian ★★★★★

Used these on my fuel rail and not a single drip since installation. The aluminum material crushed evenly with a standard wrench, which I was worried about. Solid pack for the price.
