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 Its €35,00 ($36 USD), and shipping for me would be like $12 USD. But it looks pretty interesting. If anyone tries it out, please do let me know how well it works.
Trick of the trade tread worthy if you ask me post it there as well please.
You got it.
Hope this helped.
