Gruvlok® Xtreme™ Lubricant has been developed for use with Gruvlok® couplings in services where improved lubrication is beneficial. This lubricant has an operating temperature range from -65 to 400 deg F (-53.8 to 204 deg C), well exceeding the temperature range of Gruvlok® gaskets. This lubricant is waterproof, thereby eliminating water wash-out and it will not dry out in the absence of water. There are five primary applications where the Xtreme™ Lubricant will provide increased benefits low temperature applications below 32 deg F (0 deg C), high temperature applications above 150 deg F (65.6 deg C), applications where increased pipe joint flexibility is needed, lubrication of gaskets in copper systems, and for the lubrication of gaskets on HDPE couplings. Since it is formulated from a non-hydro carbon base, it can be used with EPDM, Nitrile and Fluoroelastomer gasket materials. It is not to be used with Silicone gaskets.
