Pam's Jamaican Blue Baby

They go on fine. Just need a heat gun and a steady hand.

On blind entries or tight locations I heat up one side till it starts to shrink then rotate the clamp or the clamp and hose so I can heat up the other side. Once I get them both warmed up I just blast them with heat till they're tight.

I have these on my fat blu fish and they have never leaked...it's been 5 years now that I have had them on there.

They only come in black as far as I know. There may be other manufacturers though so you have to do some homework.
