We need more 4.5k Flatline Reg Seats!

[captian pinky]

From an engineering perspective, is there a different way to solve the problem?

They are different on the 3k flatlines. They use an oring instead of the urethane disk. My guess is the oring did not hold up as well as 4.5k and TK changed the design.

Generally i think the design is fine and machining a single or multiple casting molds is probably pretty doable. The problem is finding the correct material.

If your making them yourself it's not that big of an investment to experiment.

This might get you started

Just what i need another project. lol. I will see what i can do about drawing something up.
I wonder if 90 is hard enough though.

Think of the big return you will get for your time and effort, lol.

I would contact the company in the link and talk to one the experts, explain to them what the demands are and see what they recommend.

I need at least 3 of these, but am happy to invest in more if we need a batch.

Ill probably take the project on when i get done moving the shop. sounds interesting, plus i need a bunch of them too.

Unless someone else is doing it.
Would rather just buy them anyways. Lol

I think everyone would rather just buy them. lol
Let me know how i can help.

Need 2-3 myself

I wonder if you could turn some ptfe on a lathe to make the seals? It's hard but it does have a little give to it.

I have this stuff it's 5/8 diameter

Im not sure. That stuff is like cutting jello.
Maybe with special super sharp tools and a collet setup.
I've got some of that material here too

I've machined a lot of it will great success

I guess this needed but I never saw the draw of these seeing there is no degas option....

We ran them for years by just using a Pro Connect to release. It is still a great regulator.
