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.
