These guys sell o-rings in most materials available, unfortunately 10 minimum order

http://www.polymax.co.uk

Bohemia Seal (Czech Republic!). No minimum order, but range limited to nitrile o-rings mostly- http://stores.ebay.com/BOHEMIA-SEAL/NBR-70-ShA-NBR-IRHD-73-/_i.html?_fsub=719406012&_sid=887830602&_trksid=p4634.c0.m322

Fairy snuff. But if you can't, then those guys probably will be able to sort you out with what you need.

Ben please remember that water pressure increases with depth. A bath test sadly will not create much pressure. Wishing you well John.

I've used this supplier 2 or 3 times in the past. Reliable and good for O rings and also shaft oil seals (e.g Simrit.)
Not particularly expensive.

http://simplybearings.co.uk/shop/index.html

It may also be worth trying car parts suppliers. I like the idea of going along with your WTC for a fitting! I must try it the next time I go to Halfords - I can't see why they would be unhelpful.

I agree with Davy1 on his choice of supplier used them my self a few times now reasonable prices usually next day delivery and seal well within tollarances requiered and a British firm  to boot. Its a false economy to think you can make them yourself as stated in an earlier post a bath test will confirm no leaks at about a foot deep at the best when you get down to 4,6,or even 10 foot thats when leaks show up. super glue will also go brittle over time and also in the cold ambient temprature of your tube when submerged. Believe me kk their is notheing better than making something yourself cheaper but some thing you shouldnt leave to chance mate.

Ben....take heed of Mark's words of wisdom. If I were you, I'd hold on until Alfold...have a chat to Nigel or David or Alf about o rings.

Dosnt seem much point in sortin motors out if the things going to sink? Water tight first then put the nice bits in?  :o ( rushing to get the thing in the water will only end in water rushing in the thing )

Then use a sensible motor mount, attached to the equipment tray...

im sure im not missing the point , using a commercially available o ring / seal , will mean you are able to remove the end cap in the future should it be required ?

Well the motor looks like a 500 size job, so should just be a straight swap with what you have, but...!

It's a motor designed for 7.2volts, not 12 volts. Even on the required volts RPM is a bit high, but better than the motor you have.

You can run a lower voltage system, but will your water pump make good pressure on lower volts? Try it and see, or go back to plan 'b' and fit the 555 or a gearbox to the exisiting job.
