Ugly gauge plugs
You know those ugly plugs on the side of the reg. housing where the gauges go? I was at the dive shop getting my tank filled and ask if they had somthing to put in thier place. He gave me 2 chrome allen head plugs to replace them with. They have rubber o-rings on them, with flat allen heads. They look like they were made for the Timmy, no more rusted plugs!
I go there about twice a month and he just gave them to me. (must not be that expensive)
On a side note, he only charges 3 bucks for a full 4500 fill.
