Oil and transmission pipes to radiator - Part number for rubber O rings?

[Wbago]

Anyone got a part number or similar for the O rings on the oil pipes that join the back of the radiator on my 87 Chieftain?
New rad arrives tomorrow :-)

Usually I just get out my o-ring kit and whatever fits. The radiator may need adapters so you might want to wait till it gets there to see what you actually need.

It shouldn't, it's made from my old bits :-)

Oh, I thought you gt a new one. Most O-ring kits will have what you need but I don't know if you have the standard US style round O-rings.

I'll get a kit, easier if there are no fixed size.... 
Imperial measurement should be the one I reckon.. I use some on tattoo machines, but they're a bit big lol :-)

All the Tat guys I knew used rubber bands. Yea, if you can get an o-ring kit be sure it has the different widths along with the different diameters. It may be a larger kit but it will last you forever on most products you will ever run across. They come in handy for improvised projects too. Example, drain plug. Weld a nut to a pan, drill a hole through the pan inside the nut, slide an o-ring on a short bolt and run the bolt in the nut just snug. Instant drain plug. The rubber o-ring will seal it and also keep the bolt from backing out. If you want to get real artistic (taking into account your trade) get a Dremel tool and grind a small relief groove in the inner diameter of the bolt head for the o-ring to sit in and then you can tighten the bolt.

Here are a couple I would suggest, the HBNR are good to have for AC work.

Rad went in today :-)
O rings were fine, I got a 419 piece set for 5£ :-)
And on tat machines, the rubber O goes on the springs, softening the bounce.... The rubber bands go round the needle, keeping it Obe side of the tube :-)
