Attention to galling or seizure of treaded portions

It is said that in general stainless steel is likely to have galling or seizure because its thermal conductivity is lower

than ordinary steel and the thread surface develops larger heat and expands more.

Galling or seizure can be reduced by taking appropriate actions but in fact existing technologies cannot eliminate

galling or seizure as well as contamination by foreign matters completely.

For the threaded portions of this device (center rod and cap nut, and center rod and cover), stainless steel is used.

Therefore, please use the device in an appropriate manner while paying attention to the items described below in

order to prevent galling or seizure.

■

In order to prevent galling of stainless steel components, surface coating or appropriate lubricant should be used

to reduce friction and to improve thermal conductivity.

■

Neither special disposition nor treatment is applied for the threaded portions of this device. Please use the

lubricant optimal to your working conditions.

■

When you remove the cap nut, take the most care not to let the threaded portion contaminated by foreign matters.

When you install it, fasten it with the specified torque at maximum.

■

In case you have not removed the cartridge for a long time, the threaded portions may be solidified. In that case,

check the threaded portions of the center rod, cap nut and cover if anything sticks to them after the components

are removed. If anything remains, take it away before reassembling the device.

■

When you assemble the threaded portions, first turn them a few times manually to verify there is no galling. Then,

use the tools to fasten them.

■

If leakage of the fluid used occurs to the sealing portions of the shell gasket or the nut gasket, fasten the cap nut

with the specified torque at maximum. Then, if leakage cannot be stopped, the gaskets may be deteriorated,

damaged or deformed. So, please replace them by new ones and fasten them again.

■

If you forcibly fasten the threaded portions, it may cause galling. So, never fasten them with force.

Please understand we do not include galling or seizure of the threaded portions of this device in our

guarantee.
