FX FX Dreamline O-ring List, All variants

This is a O-ring parts list for all variants of FX Dreamline. To be used by future searchers so they don't have to do the work of looking everything up like I and others have done. Use the PDF link in this post for reference. All the o-rings can be found in one website which saves money and it will cost ~$30 Shipped for all o-rings for 10+ reseals/rebuilds. Took a few hours to put this together with all the links and finding each one.

Some of the o-rings are duplicates so don't be surprised if you see the same link for a few of them (it is not a mistake).

If anyone has input on where to find the plastic washer and the rubbersteel washer M12 then link them below and i will add them to the parts list but this is meant to be for o-rings and getting them all from one place cheaply.
Download this PDF from FX Airguns support page and use the links below for reference for what you need. https://fxairguns.com/wp-content/up...-9123-1-renoveringskit-dreamline-F10122-2.pdf

27- Buna 70 O-rings 5.5 x 2mm https://www.oringsandmore.com/metric-buna-o-rings-5-5-x-2mm-minimum-25-pcs/
71- Buna 70 O-rings 13.95 x 2.62mm - 2 sizes available, one in metric which is 13.94mm instead of the specified 13.95 and then there is the non metric version, i would suggest buying both since they are cheap. https://www.oringsandmore.com/metric-buna-o-rings-13-94-x-2-62mm-minimum-50-pcs/ and the inch version https://www.oringsandmore.com/buna-orings-113-70d-fda-nsf61-minimum-50-pcs/ (after further research both end up being 13.94mm ID X 2.62mm CS so both should work, its a buna 70, 113 size o-ring so this seems to be a typo on the FX parts list since even the #113 non metric one ends up being 13.94mm ID X 2.62mm CS...

HWA-4012 is the size you need. Do not buy a bajillion of these in a kit for $10 from Amazon - the ones in their kits are too thick, and are more like 2.5mm than 1.5mm.

I just went out and measured OD and H on my Dreamline bottle's dowty seal to be sure.
