syringe help

[chesters1]

i bought this beast for sucking out battery acid from a battery to replace the acid ,its a 100ml syringe ,it wasn't cheap

trouble is the 95% sulphuric acid i drew from the bottle to dilute down to the correct mix has eaten away the rubber? washer that forms the seal.

i havn't a clue who made the syringe and the chemist said it was old stock and he had no more (wasn't old stock prices though).

does any of our care workers know if you can buy just the seals ? probably not but it wasnt i expect for innoculations or intravenous use but probably irrigation (i certainly wouldn't like an injection from it!!) cheers

at a fiver i would like to get more than one use from it! its a great bit of kit for transferring liquid ,i used it to get the brake fluid out the resivoir before removing it when i put a new one in (saved the cars paintwork from drips) 1000 and one uses!!

 

 

 

theres no makers name on the syringe so i can approach the makers.

syringes are cool the tiny ones make great spot oilers the larger ones for grease or wax and make topping up honda 90 batteries easy ,must get some more of all sizes plus the spikes.

theres plenty on ebay but nothing over a whimpy 60ml

Hmmm, You sure you bought it for transferring liquids.... Looks suspiciously like an "enlargement tool"... not that I ever ever need, or needed one..

 

Why not try an engineers merchants, they usually do a full range of "O" rings...:) If you cant get them, post or scan one, and send it, and I'll go to my Pet Engineers Merchants They can even be made to measure for awkward sizes..

hi norrie ,unfortunately (i had the same thought)its not an "0" ring is a flat washer ,i'v tried my large selection of rings but they are either to fat when mounted or too thin and squash into the groove ,if you put on several (to fill the deep groove )then the top "O" ring isnt flexible enough to adjust to the bore or if you use a thinner one on top it comes off

the washer (before it desolved) had a very thin outer "ring" (half the thickness of the washer itself) that was flexible enough to form a seal on the bore ,my mrs just whisked it away for a elastic band washer and failed miseably

Hmmm, Well scan one, mail it to me... and let me know how thick it is, I'll go up on Monday, its amazing what they hold in stock..... Its like the Harrods of the engineering world...they havent been stumped yet mate...if they cant supply, for certain they will know where to get them,..nothing to lose, so....

 

BTW, could you make one from sheet neoprene of the same thickness??

[chesters1]

not sure i could cut it with microscopic accuracy

the center hole is approx 28mm across ,the outer would have been approx 41/42mm across (from outside to outside) and its approx 2mm thick,

note to myself buy digital calipers

 

i noticed it had perished when 95% sulphuric dripped onto concrete as i moved from the concentate bottle to the glass mixing bottle

you can just see the finer ring on the outside (well whats left of it)

 

the chip s an unfortunate dismantling error which makes it unable to enlarge errrr suck anything now.

 

pretty poor show manufacturing wise how could nasa take acid blood samples from aliens?

So, I take it , it has a "step" on it, on the outside of the washer??? so to speak?? did it shrink any ??

 

D'you want a set of calipers sent down..got a set here you can have, old, like me, but I dont use them:)

no it dissolved away ,got mechanical calipers but dodgy eyesight ,i will get a digital display one off ebay next payday,i used to make pcb's down to 0.05mm track gap now i cant even see the whole board

 

tried using my "fagin" or tight jewlery buyers eye glass attachements but even they can't help measure something thats not there

 

 

in trying to find them i see the 6oml ones are great for filling namod steam engines FEERRRETTTT!

Not sure if it will help Chesters ...

 

Catering/Kitchen shops and suppliers do a very similar thing for piping icing/potato mash etc.

Right Dave, So, Two neporene washers on top of each other 1mm thick should do it then...will work out the sizes, and take the pic up with me on Monday..
