"Low viscosity silicone grease for regulators and O-ring maintenance. (Non-Toxic) 20 grams."
20ml of fluid supplied in an LDPE bottle w/ a polypropylene screw cap. Has a narrowed outlet, to dispense a drop at a time if the bottle is squeezed slight whilst upside down.
Just apply a drop on your filling probe after every 2-3 fills and fill your rifle up as such - the fluid will dispense through the reservoir, coating your O-rings and seals, also the regulator if applicable, as you fire your rifle.
Safe to use in PCP rifles, won't combust nor ignite under high pressures or temperatures.
A little bit goes a long way - please apply sparingly as this liquid has a low viscosity - too much and your reservoir port might gunk up.
