B2 with miflex hose

[flspy]

Love my B2 but it feels like the standard rubber hose drags through the water and pulls my mouth- even with the swivel.

Anyone with their out to a miflex? Supposedly you just use a jam nut and ditch the swivel?

Also, is diving with shorter primary hose dangerous?

I put a miflex on my wife's after we discovered a leak in the swivel a couple years ago. No issues what so ever, just had to purchase the jam nut. I even have a spare jam nut for mine that I've never moved to.

I'll save the last question for a professional.

As said above and as you figured out, remove the swivel, replace it with a jam nut. Then add on the hose.

As for going to a shorter hose, how much shorter? Most go to a longer hose so making donating the reg easier. Shorter the hose the more pull one gets when turning. So even with a milflex hose, going shorter you might just end with the same problem as with the swivel hose.

Is Miflex more comfortable even without swivel?

When people swap length for length a swivel hose with a milflex hose most seem to feel less pull thus more comfortable. I have not heard about folks going to a shorter hose - not saying they have not but I have not read about such cases. I would not suggest it for both comfort but for reg donation (regardless of what backup you have).

That said those who go the long hose route (5' or longer) using a milflex hose have reported the milflex hose being too floaty and most seen to prefer a rubber hose.

What is a good size to replace the standard hose with? The longer length for reg donation makes sense.

What is a good size to replace the standard hose with?

Seems like 28"-32" is normal for the primary with 36" for a secondary (octo).

However, those who run long hose primary sometimes have the secondary on a shorter 24" hose. I run a long hose primary (5' or 7' depending on the dive) and my secondary is on a 28" hose.

I use a 40" hose routed under my arm to a 90deg. elbow on the second stage. It works very well for me. Just be aware that you have to keep control of your reg. if you just spit it out it will bang into almost everything on the boat.

 

[flspy]

Is there much difference between the 90 degree and 70 degree elbow?

 

[PACKRMAN]

I think it is 20 degrees. I will have to confirm that though before I can say for sure.

Sorry, I couldn't resist.
