GASKET RECOMMENDATION LISTING
VACUUM SERVICE
Where more than one gasket grade is shown the preferred gasket grade is listed frst. Where the gas-
ket grade is shown in parentheses, Contact a Gruvlok Representative for an engineering evaluation
and recommendation. Specify gasket grade when ordering. Use Gruvlok lubricant on gasket. Check
gasket color code to be certain it is recommended for the service intended.
Unless otherwise noted, all gasket listings are based upon 100°F (38°C) maximum temperature
service conditions.
For services not listed, contact a Gruvlok Representative for recommendation.

The lists are provided as an aid in selecting the optimum gasket grade for a
specifc application to assure the maximum service life.
The recommendations have been developed from current information
supplied by manufacturers of the elastomers, technical publications, and
industry applications. The information supplied should be considered as a
basis for evaluation but not as a guarantee.
Selection of the optimum gasket grade for a specifc service requires the
consideration of many factors; primarily temperature, fuid concentration,
and continuity of service. Unless otherwise noted, all gasket recommendations
are based on 100°F (38°C) maximum temperature service condition. Where
more than one gasket grade is shown, the preferred grade is listed frst.
Combinations of fuids should be referred to a
Gruvlok Representative for an engineering evaluation
and recommendation. In unusual or severe services,
gasket materials should be subjected to simulated service
conditions to determine the most suitable gasket grade.
Gasket recommendations apply only to Gruvlok gaskets. Contact a Gruvlok
Representative for recommendations for services not listed. These listings
do not apply to Gruvlok Butterfy Valves.
All Gruvlok products marked with UL/ULC Listed, FM approved VdS and/or LPC
symbols are Listed/Approved with EPDM material. For other Listed/Approved
materials, please contact a Gruvlok Representative for more information.
