APPLICATIONS FOR GASKETING MATERIALS
W.I. TETRAGLAS-T/TETRAGLAS-T
Applications 300-550°F - up to 330 PSI.
Hand-hole/man-hole gaskets for boilers
Tadpole gaskets for boilers
Luting - door gasketing
Folded Tape - general utility tape for steam
air water
Round folded gaskets P.T.F.E. dipped - Tank
truck lids.
RED RUBBER SHEET AND GASKETS -
TEMPERATURE 225°F
General all-purpose rubber sheet. Temperature
to approx. 150° F - 500 PSI. Good for water and
steam applications.
NEOPRENE – TEMPERATURE 225°F
General all-purpose rubber sheet. Temperature
to 225°F - 1000 PSI. Good resistance to gasoline,
lube oils, animal and vegetable oils, oxidation,
ozone and weather.
VITON – TEMPERATURE 475°F
Excellent chemical resistance for severe applica-
tions. 1200 PSI.
EPDM – TEMPERATURE 275°F
Good resistance to acids, alkalis, hydraulic flu-
ids, ozone, aging, and sunlight. 1000 PSI.
TAN PURE GUM RUBBER –
TEMPERATURE 200°F
Natural rubber - 3000 PSI. Good resistance to
strong and weak alkali, ketones, esters, and
alcohol. Resistant to hydrochloric acids in most
concentrations. Poor ozone and weather resis-
tance.
BUTYL RUBBER – TEMPERATURE 350°F
General purpose non-oil resistant rubber. Good
for ozone and chemical resistance especially ap-
plications with low temperature requirements to
140°F. PSI 1000.
Also good for strong acids, salt solutions, alkalis,
silicate, and phosphate type hydraulic fluids.
Also a good choice for resistance to dilute min-
eral acids.
BUNA-N RUBBER - TEMPERATURE 250°F
Good resistance to petroleum, oils, fuels, and
solvents. PSI 1000.
HYPALON – TEMPERATURE 250°F

cals. Very good weather resistance. PSI 1500.
Gasket application include gaskets for ozone
generators.
SILICONE RUBBER – TEMPERATURE 400°F
Good resistance to alkalis, oil, gasoline, ozone,
weather and sunlight. PSI 500.
VEGETABLE FIBER
A general all-purpose gasketing material good
for applications to 250°F.
