McNett Silicone Grease lubricates and conditions rubber products such as O-rings and other regulator and valve system components. It is ideal for breathing apparatus, BCD's, hoses, cylinder O-rings, pressure systems, cameras and much more. In addition the McNett Silicone Grease has been specially formulated to permeate rubber surfaces to provide deep, long lasting conditioning.
