I’m in Australia and order them.. I have 2 sets arriving tomorrow as well as impellers etc.. I just make sure I order a good qty of items to make the postage cost a bit more bearable 😁

The cost of Cummins parts is frightening here.. like I said the 6bta orings are 117aud or 72euro each and I need 4 for a service to both engines.. so it’s definitely worth my trouble… 😁

Hello!

I am in Spain,so that is not an option to buy them from Seaboard. I did buy Envirokit for QSL engine from Tony,is installed and works great,but O-rings are too far away to order them.

Certainly not expensive (6BTA ones here in Aus are $117AUD EACH!!)
