  1. You should hae been a surgeon!
     
  2. The ones I have seem too thin and the cover seems to bottom out on the head ..for 12 quid I’ll see how it goes ..it was 46 for 4 from c&c ....

  4. Got the link for the eBay seller? Need some now, so will try this. Would be great if it worked, I mean stopped drips onto the HX ers.

    Nitrile Rubber is resistant to oil but it has a much lower temperature tolerance compared to Silicone. Why would you want black?

    I will fit them tomorrow and check 4mm is correct .. you can only get one per A4 sheet ... but if you ask them to cut it 25mm bigger you will get a pair ..
    Choice of colours ..
     
  8. You have a choice of colours including black in silicone ...

  9. A while ago I put all new pushrods O rings in and meticulously cleaned everything when I fitted my J tubes ....
    New cork seals and they leaked ....
    After I fitted the new silicone seals I still had a weep but on further investigation it was coming from the end Pushrod tube O ring ... rotated that and now she is dry as a bone ......
    So yes the silicone worked @ 4mm thick ..bit tricky to cut out but all good

    I will measure what size sheet you need to get two out and mail the guy on eBay
