P-315 Silicone Lubricant is recommended by Lily for use in our Epoxy Dispensers. The silicone lube will not cause the seals used in the air logic to swell like a petroleum based lubricant will. It’s also recommended for use when replacing seals in the ball valve assemblies and metering assemblies. P-315 Silicone Lubricant is sold in a 1 oz. tube.
