LUBRICANTS

GRUVLOK®XTREME

TM

LUBRICANT

Gruvlok®Xtreme™Lubricant has been developed for use with

Gruvlok couplings in services where improved lubrication is

benefcial. This lubricant has an operating temperature range from

-65°F to 400°F (-53.8°C to 204°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 fve primary applications where the Xtreme

Lubricant will provide increased benefts: low temperature

applications below -20°F(-28.0°C), high temperature applications

above 150°F (65.6°C), applications where increased pipe joint

fexibility 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.

• 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 reposition 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 accom-

plished by turning the gasket inside out and applying the

lubricant. Gruvlok Xtreme Lubricant will maintain it’s lubricat-

ing 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 fuid and the gasket surface. This is particu-

larly 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 flm enhances our fexible 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

TM

Lubricant is a Tefon®fortifed white, tasteless

and odorless grease made from Silicone Oil and other ingredi-

ents that are safe to ingest. It is sanctioned by the FDA under

C.F.R. 21.172.878 & 21.177.1550 (Incidental Food Contact). It is NSF

approved for use with potable water.

CAUTION:

Silicone based lubricants are not allowed in some facilities. ®Tefon is

a registered trademark of Dupont.

GRUVLOK®QUICK DRY LUBRICANT

Gruvlok®Quick Dry Lubricant is a fast drying lubricant that has

been developed for applications where the piping system is

exposed. The service temperature range for this lubricant is from

0° F to 150° F (-17.8°C to 65.6°C) and may be used with all Gruvlok

gasket material grades. The lubricant is made from a water

emulsion that is non-toxic, it will not impart taste or odor, and

does not support bacterial growth. Gruvlok Quick Dry Lubricant

is non-corrosive, non-fammable, and is NSF approved for use

with potable water.

This lubricant is easy to apply by brush or hand, and it quickly

dries to a thin flm when in contact with air. It is water-soluble.

The quick drying quality of the lubricant eliminates lubricant drips

caused by over lubrication. If necessary, reapply lubricant prior

to assembly. Do not thin or mix with solvents.

GRUVLOK®LUBRICANT

Gruvlok®Lubricant is the standard lubricant that has been provided

for use with Gruvlok products for years. Gruvlok Lubricant is

water soluble, non-toxic, non-corrosive, non-fammable, and

will not impart taste or odor. It is NSF approved for use with

potable water. This lubricant is acceptable for most applications,

however, the Gruvlok Xtreme Lubricant and Gruvlok Quick Dry

Lubricant are now available to improve the performance of the

couplings and fanges in certain applications.

CAUTION:

HDPE pipe requires the use of Gruvlok Xtreme Lubricant and should not

be used with Gruvlok Lubricant.
