Rubber or Fibre 🤔

[bobandjanie]

I am going to change all the o ring seals on the van gas regulator and hoses, got me thinking about fibre because some pig tails come with them, so are they better or should I get some more neooprene rubber ones. Bob.

Without seeing them, I would suggest changing like for like as the seating faces may be a slightly different design, depending on if they're meant to be used with rubber or with fibre ?

Use fibre.
Rubber/Neoprene/Viton 'O' rings can squidge/distort out of place when tightening the joint and fail to seal.
Where 'O' rings are required one of the mating surfaces will usually have a groove to locate/retain the 'O' ring.
As jockaneezer said, to be on the safe side replace like for like.

I always use fibre ones on lpg installations rubber ones tend to squish and they deteriorate

Thanks for your replies I was thinking fibre, I probably over tighten rubber, and I know I've replaced pigtails and they vary some have rubber some fiber, so thought I know I will Google truma pigtail imagines maybe give me clue and they have both like this one rubber on the bottle fibre on the regulator.
