Hi all. I am looking for the plastic/derlin seal that goes on the end of the regulator on the air venturi avenger. Does anyone know where I may be able to source a few? I would like to have spares and replace the one that I destroyed.

If its a simple OD like .25" you could order 1/4" delrin rod, and fabricate your own, if you so much had the desire, simple piece of simple construction imo.
You could also expierement with other materials such as peek or pei.

I measured the opening and it came out as 3.80 mm. I ordered some 4mm delrin rod. I tought maybe I could purchase I already made ones. I just have hand tools available.

You likely can purchase them made-ready, but probably quicker (and cheaper) to fab yourself. Its possible they used a softer nylon type material where delrin would be an upgrade, as the plastic shown in your picture is glossier than any delrin I've seen!

A bit of heat from a heat gun or the like should be able to soften up the old one for removal

Or if you have compressed air available, blow through the vent hole in the side of the stem (shown just above the o-ring in the OP's image in post #4). The delrin will fly out (so go easy, and keep it covered somehow....unless you don't care where it ends up).

Ninja uses a 4mm ball in their regulator pistons, pressed in with an interference fit. That might be an option here if the piston will accept it but an interference fit of 0.2mm (.008in) seems like it may be too tight. I don’t think I ever pin gauged the counterbore but my guess is it’s 3.9mm.
If you want, PM me your address and I’ll put one in the mail for you to try. If it works, you can get them inexpensively from McMaster. https://www.mcmaster.com/9614K73

Thank you for the offer, but I'm good for now. Both of my avengers have regulators in them then I also have 3 new sets for when I need them. I have another regulator that I'm screwing around with. Any benefit if I were to enlarge the tiny hole and make it a little larger?

By tiny hole, I assume you’re talking about the one the plastic seal meets up to. Enlarging it will theoretically allow the pressure to recover more quickly after a shot, but simultaneously make the regulator more susceptible to pressure creep and nonlinearity. The simple answer is no it’s probably not a good idea unless you either have specific knowledge that a faster recovery would benefit you, or you want to do it for the learning and are willing to accept that it may not work out satisfactorily.
