Introduction
This instruction provides the proper techniques and procedures for the surface preparation and application of 8C-8422, 1U8-846 and 4C-5300 Gasket Maker (Flexible).
8C-8422, 1U-8846 and 4C-5300 Gasket Maker (Flexible)
NOTE: The part number reflects the quantity of the Gasket Maker:
Will be referred to as GASKET MAKER in this instruction.
The GASKET MAKER is a flexible gasket material that cures on active surfaces (iron, steel, aluminum) without a primer.
The GASKET MAKER does not cure outside of the joint.
The GASKET MAKER features:
- * Moderate strength for thin flexible flanges
- * Service temperature up to 177°C (350°F)
- * Large gap fill, up to 0.5 mm (0.20 in) .. and
- * Fast cure speed
- * Service temperature up to 177°C (350°F)
It can be applied via:
- * Screen printing
- * Roll coating
- * Manually
- * Automatic tracing
- * Pneumatic caulking gun
- * Roll coating
6V-1541 and 4C-9500 Quick Cure Primer
The proper application and curing of the GASKET MAKER requires the surface(s) to be prepped with a quick cure type of primer/cleaner.
NOTE: The 6V-1541 and 4C-9500 Quick Cure Primers are packaged in 178 ml (6 fl oz) containers. The part number reflects the type of dispenser and will be referred to as PRIMER in this instruction:
8T-9011 Component Cleaner
The 8T-9011 Component Cleaner is the recommended cleaning solvent and will be referred to as CLEANER in this instruction. Isopropyl alcohol can also be used.
NOTE: The 8T-9011 Component Cleaner is NOT for use on Deutsch multi-pin connectors.
Application Procedures
Pneumatic Caulking Tools
NOTE: The recommended pneumatic caulking tools are:
- * Model No. SEMCO 550 (MRS Industrial Part No. 231551)
- * Pressure Regulator .. Model No. SEMCO R07-200-RNKA (MRS Industrial Part No. 234567)
NOTE: Pneumatic regulators must be set at 103 to 138 kPa (15 to 20 psi).
Surface Preparation
Surfaces to seal must be free of dirt, grease and oil.
| NOTICE |
|---|
Do NOT use liquids such as kerosene or diesel fuel to clean surfaces. The use of petroleum base solvents leave a residue preventing the proper curing of the GASKET MAKER. Use only the recommended or alternate cleaners in this instruction. |
Adjacent Parts and/or Surface Protection
Adjacent parts and/or surfaces must be protected during the cleaning operation.
If surface material to be sealed is resistant to corrosion the recommended PRIMER, in this instruction, must be used to prime activate the surface to allow the GASKET MAKER to cure.
NOTE: The recommended PRIMER, in this instruction, may also be used for fast cure.
Remove dirt, grease and any oil from both mating surfaces.

Do NOT use liquids such as kerosene or diesel fuel to clean surfaces. The use of petroleum base solvents leave a residue preventing the proper curing of the GASKET MAKER. Use only the recommended or alternate cleaners in this instruction. |
The recommended PRIMER, in this instruction, may also be used as a cleaning solvent.
NOTE: Using the recommended PRIMER as a cleaner does NOT provide a primed surface.
If surface material is resistant to corrosion, prime activate one surface using the recommended PRIMER. Allow the surface to air dry.
Service Installation
Disassemble Joint
Disassembly is best accomplished by separating components through tension.
NOTE: The recommended GASKET MAKER is weak in tension but strong in shear.
2. Remove original cured GASKET MAKER material from both mating surfaces by scraping it off with a sharp putty knife or removing it with a 3M SCOTCH BRITE Green Pad or equivalent nylon abrasive pad.
NOTE: It is preferred to remove all cured GASKET MAKER, however, GASKET MAKER that is firmly adhered to the surface may be left in place providing there is not an excessive buildup and the recommended PRIMER is used to activate the surface.
3. Remove dirt, grease and any oil from both mating surfaces.

Do NOT use liquids such as kerosene or diesel fuel to clean surfaces. The use of petroleum base solvents leave a residue preventing the proper curing of the GASKET MAKER. Use only the recommended or alternate cleaners in this instruction. |
The recommended PRIMER may also be used as a cleaning solvent.
NOTE: Using the recommended PRIMER as a cleaner does not provide a primed surface.
4. If surface material is resistant to corrosion or if firmly cured GASKET MAKER is left in place, prime activate one surface using the recommended PRIMER.
Allow the surface to air dry.
5. Apply the GASKET MAKER to both mating surfaces.
6. Inspect both mating surfaces to ensure the GASKET MAKER applied to one surface will contact the mating surface.
7. Apply GASKET MAKER in an unbroken 1 - 2 mm (0.040 - 0.080 in) diameter bead onto one of the mating surfaces.
NOTE: Use the same diameter bead to fully encircle all bolt holes.
When applied as a bead, GASKET MAKER may be laid down on a primed surface.
8. GASKET MAKER applied to flange surfaces may be rolled across full flange with a smooth wooden roller or applied by silk screening.
GASKET MAKER applied in these methods should be placed on the unprimed surface.
Assemble components as soon as possible to eliminate the potential of foreign matter collecting on the surfaces to be sealed.
Assemble Components
1. Assemble complete, including tightening fasteners to the specified torque.
2. Remove any excess GASKET MAKER that has extruded from the joint with the recommended CLEANER.
3. Allow the assembled and tightened joint to cure for thirty minutes before performing any pressure checks or installing oil.
For testing sealed joints, apply air pressure at 34 kPa (5 psi).
Use a soapy water solution check for leaks.
If leaks occur, disassemble, clean and reapply GASKET MAKER.
