### ⭐⭐⭐⭐⭐ great for saltwalter tank plumbing
*by J***H on March 13, 2020*

Used them to secure braided vinyl tubing, worked great.

### ⭐⭐⭐⭐⭐ A must have article!
*by R***A on May 9, 2021*

The media could not be loaded. Perfect fitting, strong, great material quality, no rush no no surprises and headache for weak slip by biofilms, this is a 1” vinyl hose into a marine aquarium! God job!!

### ⭐⭐ Might work for you
*by B***2 on January 23, 2025*

But not for me. Just will not get tight enough. Just used a piece of copper wire to twist as a clamp and stop the leaking hose.
