FORM-IN-PLACE GASKETS

There are numerous places where form-in-place

gaskets are used on the engine. Care must be taken
when applying form-in-place gaskets to assure ob-
taining the desired results. Bead size, continuity, and
location are of great importance. Too thin a bead can
result in leakage while too much can result in spill-
over which can break off and obstruct fluid feed
lines. A continuous bead of the proper width is essen-
tial to obtain a leak-free joint.

Two types of form-in-place gasket materials are

used in the engine area. Mopar Silicone Rubber Ad-
hesive Sealant and anaerobic gasket materials, each
have different properties and cannot be used inter-
changeably.

MOPAR SILICONE RUBBER ADHESIVE
SEALANT

Mopar Silicone Rubber Adhesive Sealant or equiv-

alent, normally black in color, is available in three
ounce tubes. Moisture in the air causes the Mopar
Silicone Rubber Adhesive Sealant material to cure.
This material is normally used on flexible metal
flanges. It has a shelf life of one year and will not
properly cure if over age. Always inspect the package
for the expiration date before use.

MOPAR GASKET MAKER

MOPAR Gasket Maker is an anaerobic type gasket

material normally red in color. The material cures in
the absence of air when squeezed between two metal-
lic surfaces. It will not cure if left in the uncovered

tube. It is normally red in color. The anaerobic ma-
terial is for use between two machined surfaces. Do
not used on flexible metal flanges.

GASKET DISASSEMBLY

Parts assembled with form-in-place gaskets may be

disassembled without unusual effort. In some in-
stances, it may be necessary to lightly tap the part
with a mallet or other suitable tool to break the seal
between the mating surfaces. A flat gasket scraper
may also be lightly tapped into the joint but care
must be taken not to damage the mating surfaces.

SURFACE PREPARATION

Scrape clean or wire brush all gasket surfaces re-

moving all loose material. Inspect stamped parts to
assure gasket rails are flat. Flatten rails with a ham-
mer on a flat plate if required. Gasket surfaces must
be free of oil and dirt. Make sure old gasket material
is removed from blind attaching holes.

FORM-IN-PLACE GASKET APPLICATION

Assembling parts using a form-in-place gasket re-

quires care but it’s easier then using precut gaskets.

MOPAR Gasket Maker material should be applied

sparingly 1mm(0.040 inch.) diameter or less of seal-
ant to one gasket surface. Be certain the material
surrounds each mounting hole. Excess material can
easily be wiped off. Components should be torqued in
place within 15 minutes. The use of a locating dowel
is recommended during assembly to prevent smear-
ing the material off location.
