Replacement O ring seals

[Iron Giant]

Just emailed them. Thanks mate. How do you find these things, I search forever and couldn't find a thing.

Quick Google, the trouble with Google is you can search and search and sometimes not find what you're looking for, then one day do a search and you have different results I have found this a few times and it's a p.i.a

Viton 75 has been recommended by the first company. The second one (Polymax) want more info about its application which I've just given them. They are much cheaper than the first one though.

In the meantime we got soaked when the system started today. Changed them over and ordered another 50 from eBay to last us. The 50 was £3.65.

Can anyone tell me what size bsp the thread is that’s needed for the inlet hosetail on these? Looking to replace it with a rectus 26!
Thanks
