Installing Continuously Glued Gaskets

1. Make sure the gasket groove area is clean and dry prior to

regasketing.

2. Apply a uniform layer of adhesive in the appropriate

gasket grooves. (A plastic bottle makes an ideal applicator,

provided the tip of the applicator is designed to provide a

bead that is approximately 1/8 in. wide.) Do not apply

adhesive in amounts that will allow it to ooze out when the

gasket is pressed into the groove. Apply adhesive at room

temperature (70°F). After the glue is applied to the plate,

it should be allowed to set for a minimum of 30 sec before

the gasket is set in place. Work on pairs of plates to allow

for this curing time.

The recommended adhesive for all elastomeric gaskets is

Pliobond 30. Pliobond 20 and 3M 1347 can also be used,

if Pliobond 30 is not available. Hardening adhesives are not

to be used. The number of gaskets that can be glued from

one pint bottle of Pliobond 30 glue may be approximated

as in Table 10.

3. Position the gasket on the plate making sure that the

recess in the gasket at the bleed passage location is up. Also,

when the proper side is up, the gasket code number will be

visible in the bleed passage area. Proper groove ﬁt and ﬂow

diverter access is dependent on end-to-end positioning. (See

Figures 15 and 32.)

4. Using ﬁnger pressure, ﬁrmly press the gasket into the same

grooves from which the original gasket was removed.

5. Compress the gasket by placing the plate under a weighted

sheet of wood. The longer the compression time, the better

the bond. Twelve hours cure time at room temperature (70°F)

should be allowed to assure minimum required adhesion

of the gasket to the plate for all elastomers except EPDM.

EPDM gaskets require a minimum of 24 hr cure time at

room temperature (70°F) to assure an adequate bond. (When

several plates are being gasketed, they can be stacked on top

of each other with the weighted wood sheet placed on the

top plate of the stack.)

6. After compression time (step 5), use solvent to remove any

excess adhesive that may have seeped out past the edges of

the gasket.

7. Reinstall plate(s) in the unit insuring that the gasket surface

and the sealing surface of the plate ahead are wiped clean to

provide a positive seal.

8. Note that the “D” plate (always the plate next to the ﬁxed

frame end) requires different gaskets. The purpose of the

“D” plate is to prevent ﬂuid from ﬂowing across the ﬁxed

end frame. The only sealing surface on the “D” plate is the

port hole gaskets. “D” plate gaskets for the UX series consist

of two half gaskets. “D” plate gaskets for the GFP-030 and

GFP-080 plates consist of four port hole gaskets and straight

strips, which ﬁt in the gasket groove around the periphery of

the plate. The wide port gasket ﬁts the widest groove, and

the narrow port hole gasket ﬁts the narrow groove.

NOTE: Refer to page 24 when using mixed gaskets.
