base, it can be used with EPDM, Nitrile and Fluoroelastomer gasket materials. It
is not to be used with silicone gaskets.
•
In low temperature applications the gasket will shrink, thereby lowering the
sealing force on the gasket sealing lips. The temperature change will also force
the gasket to slightly re-position itself. This will cause pipe end sealing
surfaces, with small cuts or damage, to become more susceptible to leakage.
Gruvlok Xtreme Lubricant will maintain it’s lubricating properties at lower
temperatures allowing a properly lubricated pipe end and gasket (assembly) to
re-position itself during temperature cycles.
• For high-temperature service and copper systems, it is required that the gasket
be lubricated not only on the outside, as with the normal installation of a
Gruvlok gasket, but also on the inside. Lubrication on the inside of the gasket is
easily accomplished by turning the gasket inside out and applying the lubricant.
Gruvlok Xtreme Lubricant will maintain it’s lubricating properties at higher
temperatures, allowing a properly lubricated pipe end and gasket assembly to
re-position itself during temperature cycles. Lubrication of the pipe end and
gasket will help the gasket to adjust into the proper sealing position during
temperature cycles. The lubricant on the interior of the gasket will act to
improve the chemical resistance of the gasket material by providing a thin
lubricant barrier between the piping system fluid and the gasket surface. This is
particularly important at higher temperatures where oxidizing agents in the
piping system become more aggressive. However, gasket chemical
compatibility must still be considered.
• The Gruvlok Xtreme Lubricant has been formulated from low viscosity, non-
petroleum based oils to ease spreading of the lubricant. In applications where
pipe movement is expected, proper lubrication of the gasket’s exterior assists
the gasket into the proper sealing position as pipe system movement occurs.
This lubricating film enhances our flexible coupling gasket’s ability to
compensate for axial, transverse and rotational pipe movements.
• Gruvlok Xtreme Lubricant is the only Gruvlok lubricant that is to be used with
Gruvlok couplings and gaskets in HDPE and copper piping systems. It’s low
temperature capability and lubricity ensure a highly reliable connection.
Gruvlok Xtreme Lubricant is a Teflon fortified white, tasteless and odorless
grease made from Silicone Oil and other ingredients that are safe to ingest. It is
sanctioned by the FDA under C.F.R. 21.172.878 & 21.177.1550 (Incidental
Food Contact).
Caution: Silicone based lubricants are not allowed in some facilities.
