Carrera oil fed tensioner upgrade on 1979 3.0 SC, sealing ring

[3.0schotrod]

Hi all,

My car was converted to oil fed tensioners years ago, the oil line on the right of my car has started weeping oil and I have the new cohline oil line part # 930-107-348-12. I ordered it over a year ago, and I ordered sealing rings at the same time for the banjo style fitting, the 2 x aluminum washer type rings. Now when I look at the sealing rings I bought, they look like copper, not aluminum. Will copper ones work ok, rather than aluminum ones. The only issue I can think of is expansion rates could be different, but would that even be relevant for a sealing ring that size ?

The aluminum ones on pelican look to be part # 900-123-116-30.

What do you think, safe to proceed with copper ? Thanks.

No problem.

Thanks John Walkers Workshop.

Will proceed with the copper.

Any tips for ensuring sealing on all 3 connections, other than dont overtighten. I was going to get it in there and just snug everything up on the 2 x left side, not tighten, then fit the banjo side and snug up and not tighten, then nip everything up but not overtighten.
