Love your videos, great source of information and knowledge, keep them coming. Best regards from Lisbon, Portugal.

Timo Witte says:

Some people seem to have problems with older / worn flex hoses when they use a dry suit, as the fibers sticking out of the worn flex hose might puncture the dry suit. Guess this is not a problem with wet suits / new flex hoses.

clempple says:

thanks Alec, enjoyed your videos. Was hoping if you could share your thoughts on Integrated Octopus. thank you.

Billy Z says:

What are some good flex hose brands you could recommend that are high quality? Also would I have to get anything special to make these flex hoses work with Scubapro A700 primary, R195 octo and mk25? The fittings should work out of the box?

Miguel Gerov says:

Alec, thank for this independent educated information about hoses. Keep the good work!

Tayguara Pereira says:

Hello Alec.
I’ve been following your Tech Tips and used them as guidelines to buy my diving equipment, so I congratulate you and Kevin(?) on the great job and hope you keep posting more vídeos.
In this vídeo you mentioned to change the old hoses for the new flex ones. Great idea!! So, how about a Tech Tip on how to, 1st check your old rubber hose to see if its on good shape, 2nd how to change the hoses, what kind of tools do you need, torque, etc.
Just one idea I would like to see.
Thank you.

I remember when I bought my xtx 50 Apeks regulator as a package ( 1st, 2nd and octo ), there was a flex hose in the box from the manufactory!! if they were not safe, I don’t think apeks will sacrifice their reputation for a hose!! 

what makes any hose not safe is the fact that people don’t replace them even after 5 or 10 years !!

Tony Wood says: Alec, What do you think about this report?

Joel Perron says:

Will definitely check for flex hoses when I buy my first kit after certifications

Jude C says:

Great info as always Sir!


Could you post a video on essential scuba gear/accessories

Michael Anthony says:

I just watched a video by 50ft below on flex hoses with an issue of crystals forming on the inside of the hose from rapid temperature change. Will you please comment on that?

IM35461 says:

Alec, the flex hoses look very nice but in the UK if we send regs to be serviced often they will be sent back serviced but left with the non OEM hoses left off the 1st stage as the combination invalidates their EN250 approval (a card explaining why enclosed with the regs). The same also if the combination of 1st and 2nd stage has not an approved as a EN250 tested combination.

Caleb Christopher says:

Awesome! I’m upgrading asap! Thanks for the tech tip videos, Alec! I’m learning a ton from you as a new diver.

Graham Savill says:

I personally stay away from flexi hoses, over the last couple of years, I seen a number of them fail (2 of my own). The failure point seems to be at the ends where they connect rather than the hose themselves. In the same time I only seen one rubber hose fail. For travel they are great at weight saving, however if you are diving hog lop with no hood, they rub badly on the neck.

SCUBA Drone says:

Rubber hoses are not outdated. I still prefer them.over braided for
many applications. I don’t even sell.braided over 40 inches and don’t
use them on seconds I will be having around the back of my neck. They
catch the little hairs back there and feel like.sandpaper on bare wet
skin after a bit of time in the water. In addition they tend to take a
set when coiled for storage. Their lightness also makes them very
floaty. Ok for a 22-28 inch primary for some. Not for me and certainly
not for a 5-7 ft hose. I have replaced a few of those with rubber ones
for those who thought a braided 7 was a good idea and found out

I also have some rubber hoses that are almost ten years old and are just fine on my pool regs.

Purely a personal opinion.

BTW, Thank you Alec for such a great channel!

Karl Marx says:

As always, super-great. Thanks a million, Karl.

tim wilhelmson says:

I enjoy your videos. you are very interesting. thinking about starting scuba keep up the good work thanks

uberacx says:

Great advises and humorous as usual! Love your videos. I already switched all my hoses to miflex hoses. Will NEVER go back to regular rubber hoses. These look great, really flexible, light weight, easy to store and dry. Scuba diving equipment makers really should use these hoses for at least the higher end regulator, inflator models etc. I have a BUNCH of regular rubber hoses sitting in a box at home and yet don’t know what to do with them =(

Yggdrasil42 says:

I read that braided hoses have a tendency to float, that they’re more buoyant than rubber hoses. In your opinion, is that a good or bad thing?

Adam Moore says:

Seen alot of those skinny HP hose’s fail around the crimp. I think the weight of the contents gauge pulls on the joint when out of water. Perhaps a hose protector for the joints would support it.

kaeptenxy 356 says:

well there are also some negative facts about flex hoses so new ruler hoses
a 210cm flex hose squiggles a lot more than a rubber one also a rubber hose is more smooth so its perfect fore a stage where you have to put it under rubber bands
and with rubber hoses you can see when they are damaged and you have to change them with flex hoses you can’t

tim wilhelmson says:

I have always been interested in it but I am disabled and have bad arthritis don’t know if I cant retch thing like I need to.

Greatwhite sharky says:

I find these flex hoses useful for rib diving. I usually tie a lose not on the 2nd stage etc to stop it sitting on the floor and people/equipment damaging them especially when space is tight and sea conditions rough!
