Hose Protectors?

dlegros · February 11th, 2006, 02:21 PM

From looking on here and talking to people, I understand that hose protectors are verboten.

But then in "Doing it Right: The Fundamentals..." it clearly states that "Strain relief" should be fitted to the hoses to prevent kinking (p76) and on p79 is a picture of a rig demonstrating hose routing with hose protectors all over the shop!

Would I be right in thinking that things have moved on and the book is awaiting an update?

Cheers.

We don't use any hose protectors. We have Apeks regs without turrets so using a hose protector would make it difficult to make some of the tight curves. Hose protectors also make it difficult to spot any problems on the hose. Even though it is very slight, a line can also get caught on the edge of some of the hose protectors. The manual also goes on to explain that you should constantly be checking your gear for wear and replacing hoses as necessary.

At wkpp.org it's stated that "As with all hoses, we use a strain relief." At the pictures on the site, some reg's have them, some dont.
As I'm not aware of any "official" GUE/DIR policy on hose protectors, I use them on the primary and bacup hose to take the strain off the hose (on DS4's).

Just slide the thing back while rinsing and you'll be able to spot an eventual problem.

Are you being serious? The line will probably strangle you a thousand times before the hose protector gets snagged...

So if you think the hose is kinking "to much" - use them.
If not - then dont.

This is mentioned on the DVD, namely the issue as to whether a hose might need protecting is related to whether there is repeated strain (i.e. movement) on the swage not merely that it is pressured with a bend in the hose (provided that bend is static - there is no problem).

In most cases in a DIR rig, these issues are avoided by having all the hoses point down and in the correct lengths to prevent bowing (ie a hose that flaps in the breeze will put strain at the swage end). It’s also, as mentioned, going to depend on the reg. On my DS4s the only hose that is likely to move at the swage is the long hose from repeated S-drills, but having a hose protector would limit movement (i.e. pulling the hose over your shoulder), so personally I don’t bother.

I think the limited movement is the design concept of hose protectors?

I cant honestly see how the 20-30mm of limited movement can seriously affect the deployment of a 2m long hose?

Lets just be honest and admit that they look better without them :D

If you "must" use hose protecters, the soft Oceanic/Aeris type works well.

What I meant by limiting movement is being able to bend the hose such that it routes straight over your shoulder on deployment. It's going to depend on the combination of tank, wing and reg but with a DS4 and an Explorer style wing (ie - hose routed down and behind the wing) the hose protector is just going to get in the way or cause an even tighter angle in the hose as you try to pull it over your shoulder.

Try it with TX100 first stages.

You do what you want. Where I dive, (low vis lakes with trees, fishing line, cave line, cables, ropes, chain etc.) I don't want one extra thing on me that could get caught on anything.
