Tube Fitting Brass

RoHS2 Compliant

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.

Metal
  • Brass with electroless nickel plating is used for the main metal parts.
Seal rubber
  • HNBR is used for the seal rubber material. HNBR: A material with improved ozone resistance by adding hydrogen to NBR. Ideal for low-concentration ozone countermeasures.
  • HNBR or FKM is used for the seal rubber material. *Some products are only compatible in the flow path.

Options

  • No lubrication is used during assembly.

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.

Release ring cover is equipped.

As the models with the cover prevents malfunction of release ring due to spatter, it is best suitable for spatter generating atmosphere.

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.

Caution

1.When using Anti-spatter Tube, peel the cover as the following table shows. It may cause the escape of a tube, a fluid leakage or make it impossible to insert the tube into Push-In Fitting, if the tube is not peeled properly. * PISCO product "Anti-spatter Tube Cover Peeler" can help you to peel the cover easily.

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