1. Position the gasket on the plate making sure that the recess

in the gasket at the bleed passage location is up. When the

proper side is up, the gasket code number will be visible in

the bleed passage area. Correct end-to-end position is also

important for a proper groove ﬁt and ﬂuid access to the ﬂow

diverter. (See Figures 15 & 32.)

2. Make sure that the tabs of the SUPERLOCK gaskets are

lined up with the slots in the gasket groove of the plate.

1. Install double-sided tape in the center of the gasket

groove. Use continuous strips. Do not contaminate the

tape surface.

2. Do not overlap tape strips as this will cause leakage in

that area.

3. Install Teﬂon such that bleed ports (notches) in each section

in rubber core are installed in the up position.

4. Install plates per the assembly drawing that is received with

the unit.

5. Check top surface of Teﬂon and gasket seal surface for

cleanliness.

6. Install all bolts and tighten the unit (snug tight only).

7. Refer to page 30 for tightening sequence.

8. Tighten unit in 1/16 in. increments to ensure even

compression of gaskets.

9. Tig hte n to ma xi mum dime nsi on as shown on

assembly drawing.

Installing SUPERLOCK

Snap-In Gaskets

SUPERLOCK gaskets are covered under Tranter’s

U.S. Patent #4995455.

Installing Teﬂon Encapsulated Gaskets and Unit Assembly

NOTE: Refer to page 24 when using mixed gaskets.

CAUTION: On units operating in excess of 200 psig,

the tightening dimension is to equal or approach the

minimum dimension.

10. Single side hydrostatic test to design pressure shown on

assembly drawing.

11. Double side hydrostatic test to test pressure shown on

assembly drawing.

12. If unit leaks during either of the above tests, run 150°F to

170°F hot water for one hour. Let the unit cool and tighten

to average dimension as shown on assembly drawing using

same increments as in step 8.

13. Re-conduct the hydrostatic test.

14. If unit still leaks, mark plate and area of leakage.

15. Disassemble unit and check gasket and seal surface for

defects, especially at the leakage sites. If no apparent defect is

found, apply an even thin layer of “Teﬂon TFE Pipe Thread

Sealer,” furnished by McMaster Carr (www.mcmaster.com,

part #4538K1), to Teﬂon gasket at leakage site.

16. Retighten unit using same procedure as listed above.

17. Re-conduct the hydrostatic test.

18. Unit should not seal. If unit is still leaking, contact

the factory.

3. Insert each tab inside its corresponding slot and push ﬁrmly

until the tab locks into the slot. Make sure that each of the

porthole tabs (located in the bleed port area towards the

middle of the plate) is also snapped into its slot.

NOTE: Refer to page 24 when using mixed gaskets.
