HP Hose Failure

[Eric Sedletzky]

@iain/hsm Why don't you just cut to the chase and tell us what we should be buying and where?
I just went and looked and a lot of my hoses are EN 250 which is what DGX sells plus my dive shop which orders out of the Highland catalog. I have one older hose that says "Scubapro Tested - made in USA". I could take a picture and show you if it helps.
So what should I be looking for please?

I'm new to this sport. I only started in 1969 using a healthways regulator. I've been an instructor since just after the turn of the century. I've worked in shops, rebuilt more regulators than I could care to count, and have replaced more than my share of hoses. I'm sure that pales in comparison to your experience.

Oh dear. I asked respectfully for you not to continue down this route. It's sad but no matter if you wish its your call.

I am trying to understand what on earth he is talking about, but all I find in his posts are insults and attacks without any real data or specific information I can use. It's just lots of arm waving and running around in circles.

By the way, did you guys read the news about Pakistan using the latest and greatest Chinese-made jet fighters to shoot down THREE 3 of India's French-made latest and greatest Rafale jet fighters (supposed to be better than the F16) only a few days ago? I'll bet that these Chinese jets used Chinese-made components, including hoses.

I'm sure for their own stuff it's top notch. For the export market maybe not so much, IDK?

Our friend should know. He knows everything and criticises everything.

Well I was curious, so I dug out a box of hoses I have and came across one that said "Sherwood Low Pressure Tested - Made in USA - EN 250"
So now I'm really confused because according to @iain/hsm anything with EN 250 is crap scuba, so IDK?

Heck Eric again I thought I did already. LOL

Look lets take your your old mate the US Divers Conshelf XIV Supreme they used Gates 1/4" Divers hose to the SAE 100 R3 specification before the Aqualung Group took over. I listed earlier I should know I supplied the Royal Navy with 1,000's of them and wrote the Manufacturing Inspection and Test Procedure for the thing. Every nut bolt screw washer seat pin hose mouthpiece box top box bottom silver solder spec chrome plating buff and polish service and repair even the ANSTI testing reports and the modifications made but never discussed regarding external placement of the first stage for on board oxygen make up for the diving Bells and modification of the regulator for (deleted) on the (. ) military closed circuit rebreather project together with material changes from plated CZ brass to a more oxygen compliant material together with the seat polymer compound.

But I don't sell you diddly Im not a shop or your go to internet retail supplier I do work in the diving industry business but not in recreational sports products but admit the lines are hazy in some areas just as modern non disclosure agreements preclude being able to list off all the projects and work.

Now I have made the assumption that as US Divers and (deleted) are no longer around Im free to make a very basic cut to the chase disclosure as requested reply. For starters you understand. (and sorry for the deletion as the company in question they were taken over )

I did however supply the Royal Navy with 2000 pairs at a time of non magnetic jet fins that's 4000 blades and a whole bundle of ni bronze round bar. and a non mag depth gauge that didn't lower your child production potential. Its the nearest I can do to scuba gear at the moment and trust it gives me some credit in this recreational scuba diving world.

Eric as stated earlier EN250 or DEMA 250 is an inferior standard to that of the earlier models that used the industrial SAE100R3 standard
Its not only inferior but you need to understand that scuba gear is a recreational sports product now and not military of commercial or in any way near to what used to be hawked and termed "Life Support Equipment" mostly imported from the likes of China and Taiwan with your American manufacturers now pretty much closed and gone.

Now ask yourself what the folk at DEMA know about divers hose or the retail salesmen for the various brands or even the big hose supplies from Italy Taiwan or China But as a committee DEMA et al get to make the rules they have the power to create the standard however poor or inferior while you the user have neither the power to stop them or the information or knowledge to contest.

Further it say EN250 because it has to this is the new standard rules for recreational scuba hose.
The penalty for using this made purely for profit inferior standard hose is that also slipped in is the requirement to replace the hose by your local scuba shop due to its short life expectancy on your dime.

Look again at your Us Divers Conshelf XIV how long did the hoses last how often were you required to service when was spares kits banned from end users and ask yourself who benefits. Just saying.

All again when compared to the absolute stand alone professional standard of SAE

Someone please tell me if I am wrong. I understood that European standards (EN250 being one) was to facilitate trade within the EU. It is as far as I know a minimum standard
