Here's an Imgur album I just uploaded a bunch of screenshots to - https://imgur.com/a/24-45-gl45-adaptor-vHJwzqn
But since I know people don't like clicking on links, here's a few pictures from the post:
- Stainless Steel Tri-Clamp x Female Joint Adapter [1.5" Tri-Clamp x 24/40 Female] https://shopbvv.com/products/stainless-steel-tri-clamp-x-female-joint-adapter
- GL45 open top cap, found on Ebay (example: https://www.ebay.com/itm/196793301881)
- Silicone seals for GL45 caps (cheap on Amazon - https://www.amazon.com/dp/B0BR9CDZFL)
Now this solution works great for me, but when getting this post ready for yall, I stumbled across something that might work better: https://www.laborxing.com/collections/stoppers/products/gl45-screw-cap-with-ptfe-joint-adapter?variant=46214047531225
