Be Careful Tightening Hoses! - Scuba Tech Tips: S13E09

[@z00ropa]

I change my hoses all the time, taking off my drysuit hose, etc. never even thought about it. I've been lucky haven't had an issue, but now I am going to be a lot more cautious. Thanks!

Thanks for sharing Justin. A.

[@hulinda3832]

Alec, you're so professinal. And thanks for sharing the knowledge with all of us. Thanks for your work done.

[@AlecPeirceScuba_SeaHunter]

I appreciate that Hu. Thanks for watching. A.

O-rings expands and seals tighter the higher the pressure is, they are basically self sealing so they dont need to be very tight, just snug them up.

[@AlecPeirceScuba_SeaHunter]

Very true but some divers believe scuba hoses and truck nuts should be tightened with the same force. Gorilla techs is what I call them. A

[@gravitylost1]

Thanks Alan, I ‘always’ use torx bitset to extract these. Bit similar to your second screw extractor. Also works for din adaptors that got stuck over time🙂

[@AlecPeirceScuba_SeaHunter]

I have removed many stripped threads during my decades of service. Some divers just don't learn that the o-ring seals not force. A

[@ronbeatty9761]

A true Renaissance-man understands the subtleties of screw extractors. Thanks Alex, kidding aside, I learned some great tool tips!

[@AlecPeirceScuba_SeaHunter]

Glad your getting as smart as me Ron! Only took me 75 years not to screw up too bad! A.

[@jeffking981]

Great advice Alec, I have learned a lot from you. Thank you

[@AlecPeirceScuba_SeaHunter]

My pleasure! A

[@scouseflyer7242]

Thanks Alec, love the content.

Patience grasshopper... A.

[@DigginwithSeven]

Another good video with valuable information. Thanks for sharing.

[@AlecPeirceScuba_SeaHunter]

My pleasure! A.

[@kaiser76]

nice hints for my plumber workduty

[@AlecPeirceScuba_SeaHunter]

Your welcome Alesio. A.

[@Chogogo717]

In my experience extracting probably thousands of screws and fittings both types of screw extractors will swell up the broken off bits because they’re both working from the wedge principal. It definitely is complicated extracting hard fittings from softer alloy parts. The only thing I think wasn’t covered is that with the screw in type extractors you need to or can also drill the hole to the proper size to match the extractor. I’ve also made them custom by slowly grinding off the tip to get a better bite in hard to reach areas where drilling wasn’t practical. So, when it comes to torque specs do you find those in the regulator servicing manual or the hose manufacturer’s data? Great video!!!

[@AlecPeirceScuba_SeaHunter]

Your right about the screw type but I thought even 2 types might blow some minds! Thanks for sharing and watching. A.

[@petethehandyman9185]

Good info sir

[@AlecPeirceScuba_SeaHunter]

So nice of you Pete. A.

[@Bierstadt54]

I was surprised to see the end of the fitting break off; that's a nice feature. I'd expected to see the brass strip first.

[@AlecPeirceScuba_SeaHunter]

Thats the surprise many don't expect. A.

[@toriless]

Any torque after contact is for resistance only, you tighten further not to seal but to create resistance to avoid any loosening

[@AlecPeirceScuba_SeaHunter]

It is hard to convince a muscular diver that once the o-ring has proper contact, it can hold back 3000 psi/250 bar with ease. Brains not muscle are needed in diving. A.

[@twoknife]

I dive in both cold and warm water and want to pick my own regulators for this season. That means I have to change between a single first stage and two first changes perhaps two times a year. Is that an issue in terms of wear since it is a fairly soft metal or is that fine? I would need to swap the transmitter and a second stage each time.

[@AlecPeirceScuba_SeaHunter]

There is no limit on changing hoses, wear on the o-ring is the only issue if proper torque is used. I have vintage divers with 1960 regs changing hoses from dry to wet suits with never an issue. Hoses will generally wear out long before 1st stage threads ever will. A.

[@twoknife]

@@AlecPeirceScuba_SeaHunter Thanks. I guess I will ask our club technician to show me / look over my shoulder the first time. Probably gonna cost me a beer, but might be a good investment if the regs last half a century :)

[@mitchroberts6096]

I've always done hand tight then 1/8-1/4 turn.

[@AlecPeirceScuba_SeaHunter]

Or as I used to tell service trainee's, just one "umph" tight. A.

[@scubasteveandunderwaterroc3547]

Hey Alec I have a question. Have you ever been to/heard of the Bonne Terre mine? If so what do you think of it? Thanks!

[@AlecPeirceScuba_SeaHunter]

Yes I have, a really unique diving location for all skills. If you get a chance to dive different sites, mines, quarries, rivers, do it. Good experience and great stories to tell those who only hit a reef once a year. A.

[@trombonstya]

Use left handed drill bit for drilling and at 99% the broken part will unscrew

[@AlecPeirceScuba_SeaHunter]

Getting it to 1% is hard for those who don't use tools a lot. Nice tip. A.

[@owenmougenot712]

Hi Alec. I guess you are destroying more of Kevin's old hoses? A couple more variations on screw extractors are also available, first is standard schedule pipe extractors, these have straight splines that hammer into the inside of a broken pipe end and allow removal. Another is a stripped hex key bolt remover, these have a 6 sided taper that is slightly larger than the head size and can be hammered (or wrenched) into the stripped head then can be removed .The bolt is garbage but the thread is clear. Always a tool for the job, even if it is only what you have in hand. stay safe Owen m

[@AlecPeirceScuba_SeaHunter]

Hi Owen. I don't mind destroying Kevin's gear, give him an excuse to buy shinny and new! Good point on the extra tools too. Take care and thanks for watching. A.

[@ABCDiver]

when to stop tightening? when you hear a crunch!

[@AlecPeirceScuba_SeaHunter]

Ha for sure. That crunch is the sound of a $100 repair bill. A

[@lupusdeum3894]

I was wondering why you continued to turn that wrench....🦈

[@AlecPeirceScuba_SeaHunter]

Got Ya!. A.

[@ericlondon5731]

I repair guns....... Sometimes a remorseful, yet overly enthusiastic gun client will show up with a bag of badly damaged parts and tell me: "it use to be a gun". Sometimes parts just can not be found. What was working is now an odd 'paperweight'.

[@ronbeatty9761]

I did that once. It taught me the value of a professional.

[@AlecPeirceScuba_SeaHunter]

I bet a lot of service pro's have stories like yours Eric. Funny how they never did anything wrong. A.

[@jacquespoirier9071]

it is the proof that for some humans, any tool can lead to a disaster. I've even seen a professionnal plumber wrapping a Oring fitting with teflon tape. it is not a surprize to me to see that some gorillas uses tools to " repair" any equipment my best whish is that the diving equipment "repaired" that way is so damaged that it will be inoperative avoiding a failure during a dive. good point and good video

[@AlecPeirceScuba_SeaHunter]

I have soon many home repair disasters too Jacques. Glad to help the diving community. A.

[@Shabass]

You really have to thight it out to broke. Good information. And GM has made a engine with aluminium bloc and cast iron head. Not a great idea. The chevrolet vega!

[@AlecPeirceScuba_SeaHunter]

Oh yes the Vega. Engineers vs reality is a constant battle. Glad you like my talk on taming the 'inner gorilla'. A.

[@HhhHhhh-pe8qt]

[@AlecPeirceScuba_SeaHunter]

Thank you HH. A.

[@jonnieinbangkok]

I thought about it...I'll stay in Phuket 🇹🇭

[@AlecPeirceScuba_SeaHunter]

Ok. A

[@PROSTO4Tabal]

First :)

[@AlecPeirceScuba_SeaHunter]

Yes you are and thanks! A.
