250 psi actually equates to quite a heavy load.... But I will carry a spare....
ive seen others use the coupler like that for a trailer hitch and never seen them post any trouble with it on here, i bet it will do a fine job.
I would put some dry graphite lube or something in it now and then, or maybe make a rubber boot to go over it to keep dirt out and then put a little grease in there.
I had thought about use a small motorcycle shock boot as a cover if I used the air coupler since I do a lot of riding on dusty dirt roads.
