Nelson cup seal

[Kit]

Any advantage to the traccer style cup seal and thicker power tubes?

I really like the CCI one. It’s simple durable and the seal can be flipped so after many many years of use you can flip it if need be and be right back on the field. I think the CCI style is the best design and the most reliable.

The Hammer 7 design is the worst cup seal to date plastic junk that leaks all the dam time (IMO)

But the Traccer valves work good to the seals aren’t flippable tho. So if I had a choice I would definitely prefer a CCI style cup seal. But I do like the brass valve nut on the Tracer.

The Kingman hammer (old one) had a beefy power tube, too.

Some of the old ones would break under extreme autotrigger, so I'm guessing the thickness was to prevent breakage while still getting #6 amounts of flow.

But there is a demand for Trracer "short" powertubes because they break so easily.

Best,
