Do Not Use Tri-Flow - It's petroleum based and will cause your oring's to swell.
Tri-Flow® Superior Dry Lubricant is an elite formula created for dry and dusty conditions. The drip bottle application, with a convenient straw, allows for deep penetration in hard to reach moving parts. "Featuring paraffin wax and high-grade petroleum oil" to allow the lube to go on wet, but then set up in a dry, 'wax-like' film so it will not attract or absorb grit and grime. Perfect for dry, dirty, dusty conditions, while still providing adequate wet weather performance. Holds up to extreme pressures and resists water wash-off. Provides incredible efficiency without attracting an excessive amount of contaminants.
Synthetic air tool oil or Gold Cup paintball oil is the best choice.
