Warnings

* Make sure to follow the instructions below when the fluid medium is water or heat medium oil.

Surge pressure must be controlled lower than max. operating pressure when using water or heat medium oil as a fluid medium.

Tap water in Japan free from foreign substances or contamination can be used. Carry out the evaluation under an actual operating condition for using other kind of water.

Be sure to place Insert Ring (WR) into the tube edge when using water or heat medium oil as a fluid medium.

Construction

Advantages

Not only the body but also the release ring is made of brass, so that these models feature excellent flame/spatter resistance and heat resistance.

No cover type is also standardized for a variety of applications.

No cover type is recommended for the applications which does not require spatter resistance (such as piping for mold cooling).

It is compatible with special specifications.

Seal material can be changed to FKM from standard HNBR.

Detailed Safety Instructions

Warning

1.When the fluid medium is water or heat medium oil, do not use fittings unless the operating environment meets all the described specifications in the catalog. Otherwise, it may cause damage to the products, the escape of tubes and a fluid leakage.

2.This series has seal rubber material options, but there is no way to identify between each material. Store each product properly not to mix up, after opening their packages.

3.Thread body of some types in Tube Fitting Brass series is rotatable. Do not rotate and swing it by force or continuously. It may cause damage to the products and a fluid leakage.

4.Select seal rubber material considering sufficient margin to the operating temperature range. Seal rubber material can be worn out by heat and may cause a fluid leakage. Perform maintenance periodically and in case leaks are found, replace the product to the new one promptly.

5.Solidified heat medium oil on the release ring or the guide ring may cause trouble with its release / lock function. Be sure that heat medium does not adhere on the release ring and the guide ring, when using the product. Also, be sure that the tube does not escape when re-inserting it into the product.

2.Spatter may accumulate on the release ring when using Plug (PP) type.
