Source for Fly High in-sac female fittings?

[gumby]

Yes. the fitting that on screws on the tsunami pump is female.

Now I don't want to set the record straight with correct info NPT 3/4 or .75 refers to the inside diameter /ID the outside diameter /OD is what screw together. The threads will MIC. out at 1.0310. (that is center of the run on tapered) on ANY material. That said High fly Dose not use NPT. They don't have to. There system is PROPRIETARY. There fittings MIC. out at 1.0630. They are close in thread count and pitch. That is why you san screw the smaller NPT into them because they are close in size (smaller) They are not the same.That is why you can not screw a High Fly fitting into NPT. High fly are to BIG. LIKE I said "It almost like there metric". That is an assumption.(and a wrong statement) what i should have said is "IT is almost like they are Proprietary". Wait they are.
Here are some pic to help.

Hope this clears things up.

Hmm, very interesting. And frustrating. Geez, I hate it when companies ignore standards and do something like this (see my earlier ballast hose rant). It costs them money because they can't use standardized tooling, it makes things inconvenient for their customers, etc.

Generally companies do stupid things like this when they're trying to capture "all of the business" and keep others out. But who/what would Fly High be trying to exclude here?

Sounds like I'll need to contact Fly High and ask them if they based this on any sort of industry standard. Maybe, as you suggested, it's something metric like British pipe thread (yep, that's yet another "standard" to add to the list) and there will be some sort of international standards for it. I'll update this thread with whatever I learn about it.

Thanks!

If you share with us what you are trying to do. We might be able to help A little better. The things I can think of trying to connect bags together to fill with one pump. or stacking bags. witch is the same thing.But you are obviously are connecting a High fly to something Without using a hose. Witch is exactly what I was working on this summer. Quick connects were the only way I found to do it. and works like gang busters. so what i wanted to do was put a 400 (because I had two) on top if a 750( because I had two)
I thought if I used a hose it might not drain properly and might damage the bag. So i took a quick connect female into the 750. Got a tsunami female to male quick connect ground the threads out. then took a bag connector cut the barbs off and PVC glued ti into the female if the tsunami connector where I ground the threads out. This will allow you to connect bag to bag with no hose. Now it is quick connect so must align the pins before glueing. but it dose work.

I don't know why i can't get this pic it post.

Yes, the .75" is a nominal description, no an actual measurement. if you measure a nominal 1", it will be larger then 1".

I have a thread pitch gauge that will tell me if the fittings are metric or imperial.

This is for production of an electronic product that would screw directly into a Fly High fat sac fitting. The threaded portion will be part of an custom injection molded part, so it's not as simple as just finding a one-off solution... we actually need hard specifications so the tool shop can machine a single or multi-cavity mold.

BTW, I looked up British Standard Parallel Pipe and its major diameter is 26.441mm or 1.041in. Not quite your 1.06 as shown by your calipers, but closer. A Wally Plug I have sitting here measures 1.038in on an American set of calipers and 26.36mm on a metric set. Pretty darned close, just 0.3% off which could be explained by molding tolerances. TPI for both BSPP and NPS is 14, which explains why they can be screwed together without binding. so I'm hopeful that Fly High simply used BSPP instead of NPS. It will be fascinating to learn why, if they'll tell us. Perhaps some frustrated British ex-pat living in America? {grin}

Now mike could correct me if i am wrong but I think all bags are proprietary as far as fittings. High fly won't work on wake makers so on and so on. so you Product would only work on High Fly. You would have to make adapters for other bags.

[IDBoating]

Yes, that's a problem. (I'm tempted to repeat my rant against using non-standard "standards".) Frankly, I don't even want to design and manufacture this product but we're being asked to study its feasibility so here we are. If non-standardized fittings weren't a problem we have come up with a pretty sexy package, but it has to make sense financially and the fat sac companies have designed themselves out of a great opportunity here. There are other Engineering challenges too, but those are due to physics... choosing to use non-standardized fittings is a purely human stupidity problem that can, and should be, easily avoided.

There are obviously unique cases where a specialized device is required due to the application. But those are, by definition, the exception. Anyone who uses a non-standard fitting, hose, connector, etc. where something standard could be used should be fired and blacklisted from ever working in that industry again. Period. And even that may not be sufficient punishment.

Once straightline got past waterbed fittings, they adopted a 1" NPT female sac thread. Others followed suite. Fly High stayed with with the .75" straight. It also happens to be the same thta Attwood uses on the T800 I think. This could be why Fky High adopted it.

So Attwood uses non-NPS straight threads? I wonder if they originated in the UK and use British threads.

[chpthril]

On the Tsunami series, yes. And they are also the ones that used that odd 1.125" threaded inlet on the T1200, which is almost unheard of in the plumbing world.

Just playing devils advocate.

if you buy a boat that is plumed for (lets say) High Fly Now want to get bigger bags.
If they are all the same fittings high fly might loose the sale because there bag cost more than wake makers. but if have to buy all new fittings and a bag. that would cost more than just a bag.
Being different from the other guy encourages people will stay with you because of cost of replacing bag and fittings.
if you choose a standard that is out there and don't make your own. You loose sales again because the bag cost plus an adapter is cheeper than a High fly bag.
when you are not adaptable with out changing every thing or buying from them = more sales.
AS a person who modifies everything. It makes it hard to do when things aren't standard you have to work within the what they are going to give you.

It really only applies to the sac's threaded port. Also keep in mind, that I think fly high was the original, so its everyone else thats gone a different route

[gumby]

yes I agree High Fly is just an example. we could have bought a boat with Wake makers same holds true for all them I wold think. I am no bag expert.

[IDBoating]

I agree, but I'm looking at it from an Engineering/Manufacturing standpoint (which is often in conflict with Sales and Marketing!). If you do something custom, then you don't benefit from existing tooling... existing parts from vendors... basically anything that is out there. EVERYTHING you do requires new, custom tooling (read: delay and expense). If you run into a manufacturing problem, you can't just dash out and find a solution off the shelf - production is shut down until you work out some custom fix for your custom parts. Any change, any problem is a headache and a scramble and a problem for you, your vendors, your distribution chain, and your customers.

I'm all about getting into and STAYING in production. Things that slow or stop production cost money and aggravate customers. Neither of those things improve your bottom line.

EDIT:

Being different from the other guy encourages people will stay with you because of cost of replacing bag and fittings.

That works both ways. Being different from the other guy ALSO means your stuff won't be purchased after the fact for upgrades, for all the reasons you mentioned. I wonder if anyone has actually researched the marketing on this, or if they just go with the usual Sales and Marketing gut reaction of "Let's build a walled garden". I've had this argument with Sales and Marketing dozens of times in my career, and I have yet to find an example where it was a net positive. Heck, not even IBM could do it with the PS/2 architecture and it was designed SPECIFICALLY to exclude third parties from "stealing" their captive audience. If I were running such a business, I'd want to be compatible with everything so I had at least a chance at every sale... if you're incompatible you're never even in the running. Somehow the Sales and Marketing droids never realize that they're literally designing themselves OUT of so many sales opportunities; you can't make a sale when your stuff won't even work!

ID I do agree 100%. Like I said I was just playing the devils advocate, but it doesn't Change the fact that it is there sand box we are just playing in it. I am sure you will figure it out. You could always start your own bag company that goes with your new device. That would be cool. Good luck.
