Note 1) DI water is not recommended.DI water affects the materials used in the fitting,which may
lead to a deterioration of water quality.
Note 2) Check the operating pressure range of the tubing.
Note 3) Avoid using in a vacuum holding application such as a leak tester,since there is leakage.
Note 4) Check the operating pressure range and operating temperature range of the tube.

4. Troubleshooting

KFG2H*-C series Clean Design Fittings cannot be disassembled or repaired in order to quality
maintenance.
When failure such as "Non-removable tubing" occurs, please replace the whole product.

5. Construction

Stainless steel
Metal exists in nature as ore (like oxide or sulfide). This means that oxide or sulfide is more stable than pure
metal. Accordingly, metallic material chemically oxidizes (metallic constituent becomes ion and melts out). It
corrodes in the natural environment.
Even though corrosion of metal easily occurs in an environment where oxidizing tendency is stronger, some
kinds of metal have a characteristic for which corrosion never happens if the level of oxidizing goes higher than a
specific point. In such case, it is called "metal in passive state".
Stainless steel has corrosion resistance because of a thin coat of passive state on its surface. However, there
does not exist stainless steel with absolute corrosion resistance; therefore, many types of stainless steel have
been developed for improved corrosion resistance performance.
