Halcyon Eclipse with atomic ss1 inflater

[djanni]

I just bought one of these and ordered a atomic ss1 will there be any problems with matching these up??

I dont to teck just Recreational...

I don't know anything about Halcyon's corrugated hoses but as someone else said the SS1 comes with adapters. Mine had an adaper that fit the corrugated hose on a Zeagle and a separate adapter that fit the corrugated hose on a Dive Rite wing.

LOL... I'm dying to hear what the good company Halycon will say in response to your wanting to put a SSI second air on their wing...





getting the popcorn out...

Hey,,, Halcyon insists that Halcyon isn't DIR. Halcyon is making DIR gear in their product line....

I agree with Perrone, since the low pressure hoses that you use on your normal second stages are the same in terms of size and internal diameter---it's just that the low pressure inflator hose has a slightly different fitting.

Not magic, but the Atomic hose IS different.
If you compare the internal diameter of the opening the threaded
metal fitting that screws into the first stage it is noticeably larger.
Also, the rubber hose itself is slightly larger as well.
(The thread size is still the same, it is the air hole size inside the
fitting that is larger)

And for those doubting Thomas' out there I do have a picture
(which I couldn't get to attach) that I can send to you.

However, I did measure it with digital calipers.

The Atomic fitting has a 4.9mm opening and the other hose
had a 3.8mm opening.

Given that surface area is proportional to the square of the
radius of the circle, going from 3.8mm to 4.9mm diameter is
1.66 times or 66 % bigger surface area or hole size.
This should make a difference in how well air flows.
Whether the extra flow is really needed in real life, I guess could
be argued.

Math follows below:

3.8mm diameter = 1.9mm radius
4.9mm diameter = 2.45mm radius

(1.9) * (1.9) * pi = 11.34 square mm
(2.45) *(2.45) * pi = 18.86 square mm

18.86/11.34 = 1.66

NOTE: all "std" low pressure hoses may not be the same or have
the same sized fittings but this is the result of my comparisons of
actual hoses - not just supposition.

...and its probably just a coincidence that the top boy on both companies are one and the same person

The hose may be different, but it's doubtful that it's because it's necessary in order for the SS1 to get enough air. Apeks was using a 1/2" port on their primary LP port under the premise of improved performance on the primary reg. They've now effectively acknowledged that it was all marketing hype and have gone back to 3/8" on all the LP ports. What I'm saying is that an adapter on a regular hose should work just fine and you'd never notice a performance difference.
