I've tried #112 on my pinlocks because the 111 had to stretch a little which reduced the overall OD. Most of them sealed but I didn't like that tweaking the connector a bit would sometimes cause a hiss of CO2. The 112 fits a tiny bit loose on the post but seals well when the disconnect goes on. My other alternative that I like better is #111 silicone rings. They stay softer when it gets cold and I've had no problems at all.
