Decompressor blanking plug now weeping

Hey peeps

 

Anyone had the experience of the aluminium with o-ring blanking plug leaking? I think I put it in about a year ago. I guess I'll pull it out and clean it and maybe use some sealant as well this time?

Cheers Leigh.

I went with a genuine one so no experience with the alternative  maybe the oring needs replacing

That’s probably what’s happening. Anyone know the size of the o-ring?

Hi Leigh

Sorry to hear of the troubles with the O ring, will send you one FOC.

Not sure if Malcoms was the older typeconfuse

Anyone have ideas about a different type of O ring? I use Nitrile 70's in them.

It might be worth checking with your O ring supplier Steve. 

I found this article which may (or may not) indicate Viton would be a better choice?

looks like they should have been set up with Viton at the beginning.

Will have to get some in now.

Hey guys,

Pulled it out last night and the oring looked ok, I suspect it has shrunk/compressed a little. Cleaned it all up and put it back in with some sealant, especially around the back edge, I can't see that thing leaking ever again.

I also got it out by using a little screwdriver in the screw hole and managed to pop it out, so a pretty quick job.

Steve if you want to send me another oring, feel free, but I'm not too fussed, feel pretty confident with the addition of sealant. I'll let you know how it goes.

Cheers Leigh.

I have now replaced the O rings with Viton ones, if anyone has a problem with theirs, please get in contact and I will send you a new O ring. Would like to point out that I have only heard of 2 people having problems on here and appreciate the feedback, as without it I can't fix thing's.

Though I have not had a problem with my one, but reading the information on the different types, seemed sensible to change them.

Anyways all sorted now, Ta smile
