Manhole Gaskets Standards

[batman77]

Hello,

I'm new to this forum / topic.

Can someone guide me to where I can find standard dimensions for oval/obround gaskets.

I have this gasket spec and would like to understand what the dimensions are.

Spiral wound gasket, KRAJ Type KRS Gasket 465 x 427 / 420 x 382 x 4.5 thickness.

THANK you.

Which country does the spec originate from?
Maybe this could help identify it better.

Also have a look at this:

It looks your oval spiral wound gasket dimensions is specified as outside LG x inside LG on both long and short directions. So, the width of the gasket is 38(mm?).
