Hi,
Could you guys tell me what length lp hoses you would use/recomend in the following setups:

1)Halcyon eclipse 30 on single tank
2)DSS LCD 30 wing on a single tank
3)Halcyon explorer 55 on doubles, hose runnig of the right post

Just to be clear, I'm asking about the lp hose, not the corrugated hose.

Thanks, Stas

Stas,

We furnish a 18 inch LP hose with all of our wings. Exact lenght is subject to a couple variables, tank position, first stage type and hose routing both impact the exact lenght of hose required. You can't really know until you get comfortable with your new BP&W, get the tank positioned where you can reach the valve and be in trim.

The 18 inch we furnish has been well recieved.

I second that

This is very true. Different first stages has different hose routings. And different hose routings may affect the required hose length. For example, the standard 22" hose that comes with Halcyon wing is too short for my DS4s on AL80. On the other hand, the 22" is a bit too long for my MK16 on single setup.

Sorry, can't really give you a definite answer............... It all really depends........
 
I use 22" for doubles and 20" for singles. Those are what my H evolve and DSS LCD 30 came with and I was happy with them, though I guess DSS hoses may now be even shorter per Tobin's post above. This worked well for Salvo and Dive-rite regs for doubles and Dive-rite for singles (didn't try with Salvo, but I'm sure it would have worked), and the short (~ 14") corrugated hoses on the wings.

Peter Steinhoff recomends a 24" LP hose for doubles[/urlhttp://dir-diver.com/en/equipment/reg_config_doubles.html, but 22" is the DIR standard. Later when you dive more you may want to add an inch here or shave an inch there when replacing hoses. Especially with very large or petite divers may need slightly shorter or longer hoses.

We have shortened our hases a bit, but in any discussion of hose lenght you need to define how lenght is measured. Is it the lenght of the just the hose,(fitting to fitting) or does it include the overall lenght of the assembly, i.e. total lenght including the end fittings?

Our current hoses use 18" of hose, with the fittings you add about 1.5"

I meant 22" (Halcyon) and 20" (DSS) including the fittings. I thought that was the standard way to refer to them because in the past when I've ordered hoses (or regs with certain length hoses), the length has always included the fittings.

There is a lot of misunderstanding about hose lenghts, and how they are spec'd

Generally I'd agree that total overall lenght is most common, but not every user knows that.

It gets much more confusing when discussing corrigated hoses, as the elbow and inflator each add several inches, and there can be debate about where on the fittings one measures. Is it the center of elbow, or the outside edge of the nut? Is it the center of the inflator, or the end of the oral inflate button.

I'm not trying to beat a dead horse here, just illustrate the problems that can arise, and the need to be clear when ordering or comparing.

Okay, for LP and HP hoses I include the fittings in length, for corrugated hoses I only include the actual rubber hose part (no elbow, no inflator). That's how I've seen them labeled by others so that's what I use. Also, I think that's a better way to refer to them because if someone orders an 18" LP hose, for example, from a random website based on advise they got here then they are likely to receive an 18" hose including the fittings... or at least that's my experience... perhaps there's really no standard and I'll have a rude surprise when my next order of hoses from TDL arrives... But you make a good point; if you specify then there's no way to get it wrong.
 
agreed, corregated hoses should be universally measured w/o the fittings, an easy means to avoid all of this confusion. manlaw?
