Doug has a good point (and JB too).
Wouldn't ya know it, the devil is in the details.
The stock BLACK and YELLOW handles suck in the worst way.
And the odd little Italian bolt has issues with wanting to back out, and forget trying to find a repalcement screw if you loose one.
But...they are a good valve that just needed a little pimping.
When I first made the
GreenGlides aftermarket replacement handle for the Italian mini-valve, they were bullet proof.
Somewhere along the line my plastics guy sent me the wrong plastic, and we had a nightmare generation of Brittle handles that cracked. It was weird....5 would be good, and #6 was worthless. It took months to get feedback form cleaners that the handles had a material flaw.
About that same generation we also made some aluminum handles, but like the circle seal valves they transfer heat.....strong as can be, but definitely transfer heat.
I will again make some ommo handles (out of the right plastic) come spring. But for now I'm out, sold the last of my valves and handles to
John Olson at
Superior.
And now you have the rest of the story.
