S410 fill valve replacement

[big uli]

Hi all
haven't been on the forum in ages

I have lost the fill adaptor for my S410. It's a pre At gun
So I figured I replace the fill vale with something more suitable rather than buying a new fill adaptor never having regarded the T-valve as any good

Will this be a straight replacement?
Personally I think so but I figure it is best to double check

I had mine replaced as part of a service to the best fittings one , and the guy who did it said it was easy.
Just remember to empty your cylinder fully before removing the filler.
