Instructions for Plug/Holder Disassembly and Reassembly
The seal on the threaded plugs/holders found on TLV products is formed by a flat metal
gasket. There are various installation orientations for the gaskets, such as horizontal,
diagonal and downward, and the gasket may be pinched in the thread recesses during
assembly.
Instructions for Disassembly and Reassembly
1. Remove the plug/holder using a tool of the specified size (distance across flats).
2. The gasket should not be reused. Be sure to replace it with a new gasket.
3. Clean the gasket surfaces of the plug/holder and the product body using a rag and/or
cleaning agents, then check to make
sure the surfaces are not scratched or
deformed.
4. Coat both the gasket surface of the
plug/holder and the threads of the
plug/holder with anti-seize, then press
the gasket onto the center of the
gasket surface of the plug/holder,
making sure the anti-seize affixes the
gasket tightly to the plug/holder.
Check to make sure the gasket is not
caught in the recesses of the threads.
5. Hold the plug/holder upside down to
make sure that the anti-seize makes
the gasket stick to the plug/holder
even when the plug/holder is held
upside down.
6. Screw the plug/holder by hand into
the product body while making sure
that the gasket remains tightly affixed
to the center of the gasket surface of
the plug/holder. Make sure the entire
gasket is making contact with the
gasket surface of the product body. It
is important at this point to make sure the gasket is not pinched in the thread
recesses of the plug/holder.
7. Tighten the plug/holder to the proper torque.
8. Next, begin the supply of steam and check to make sure there is no leakage from
the part just tightened. If there is leakage, immediately close the inlet valve and, if
there is a bypass valve, take the necessary steps to release any residual pressure.
After the surface of the product cools to room temperature, repeat the procedure
beginning from step 1.
