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.

Gasket Surface
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.

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.
