On/Off vs Standard Screw-In ASA

[Dusty Bottoms]

I’ve been using CP on/offs for so long it’s just ingrained now for me to use them. They’re convenient, simple to use, cheap and look nice, so why not? Only my adjustable Armageddon regulator setups don’t use a venting on/off asa.

I like them for teching paintguns. Easy to turn the air on & off.

Otherwise it depends on the paintgun I'm using. I like them on my high-ends. Low ends that just need to work I use standard ASAs (no o-rings to fail). I'll use duckbills on setups that need to be lengthened, like my sniper because I use a 13/3k bottle with that. Duckbills put the bottle an inch or so further back than an on/off ASA. And almost all my bottles have brass bonnets, so I'm cool with standard ASAs.

My personal stance is pro on/off for the simple reason than tank threads last much longer if you can thread them all the way in, then pressurize them. Rather than get pressure while half threaded.

I like on-offs - they make it much easier to degas a marker, and I use them as safeties on my markers that don't have any.

SHP regged tanks are really hard to unscrew, too.

on/off's are great.
since its on the high pressure side, i doubt theres any measurable/meaningful flow restriction.

also you dont have to dry fire the marker in order to unscrew the tank. (easily)

a huge plus for me is that you can quickly cut the tank if there is an internal leak in the marker. (i tend to play with older unreliable markers)

Agreed that one of the best benefits is being able to instantly cut off gas flow when something suddenly goes haywire, instead of frantically trying to unscrew a tank.

I don’t really care too much about on/offs, historically I always gravitated towards straight duckbill ASAs or angled ASAs if going back bottle. However I almost never use an ASA on the gun to connect directly to a tank, almost always I use some sort of stock or regulator that goes between the tank and ASA.

this means a slide check valve generally made more sense to be the part that degasses rather than the ASA. I have recently moved to a triple on/off setup though as money isn’t much of an issue these days. So now I can degas the tank from my remote, I can degas the line from the tank with a slide check or I can degas the ASA on the bottom line itself if I decide to go tank on go rather than remote.

IMO there is nothing wrong with the old style, maybe you lose an O-ring or buy a new bonnet at some point but really nothing but a tiny quality of life improvement.
