## Customer Reviews

### ⭐⭐⭐⭐⭐ high quality
*by M***S on December 9, 2024*

These Type F coaxial caps are solid, one piece metal, and include a small gasket inside. They work great.

### ⭐⭐⭐⭐⭐ It worked
*by B***L on September 18, 2025*

At least they fit. Not like the rubber caps I purchased and they were to big!

### ⭐⭐⭐⭐⭐ Great for protecting COAX splitters and cables.
*by B***R on February 15, 2025*

I needed these caps to protect my COAX cables and splitter at the box outside my house. Previously my house was serviced by the internal COAX lines going to each room. However, since I began using a wireless router and NETGEAR's Powerline 500 Nano boxes, I haven't had to use the COAX cables, except for the line going to my router. I put the caps on the connectors attached to each unused COAX cable and caps on the splitter to protect them from corrosion.
