Warnings

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

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

The specification above may not be applied, depending on the kind of chemicals or mixed gases used as fluid medium. Make sure to use PISCO products after verifying their suitability on the user side.

Construction

Advantages

All-resin (PPS) made fitting, which possesses excellent heat resistance, noncombustible (UL94 V-0 equivalent) and chemical resistance and the seal is made of fluoric rubber, to meet a wide variety of applications.

One-touch mechanism contributes to easy fitting of tubes.

There is no need to worry about rust and metallic ion because the fitting is all-plastic made.

It is compatible with special specifications.

Sealing material can be change from standard FKM to EPDM or NBR depending on applications.

2 types of package are available.

Standard package and clean-room package that products are washed by clean air, then packed in ISO class 6 cleanroom are available.

Since it conforms to the Food Sanitation Act (only FKM spec.) and has completely oil-prohibited specifications, it is best suitable for food-related applications.

Detailed Safety Instructions

Warning

1.Check chemical resistance before using the products, when the fluid medium is chemicals, solvent or mixed gases. Depending on the conditions, it may cause damage to the products, the escape of tubes, and a fluid leakage.

2.When the fluid medium is water or liquid, 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.

3.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.

Caution

1.PPS resin has a characteristic of color change by being exposed to sunlight, fluorescent light, mercury lamp, high temperatures and etc. for a long term. There is no problem on the product performance for the color change.

5.Due to the resin-made collet, there is a possibility that the hard type tubes and the stem type of non-Chemical Series may have a problem of escape. Verify the matching of connections before using the products.

7.Tube insertion into this product is tighter than that of Tube Fitting Standard Series due to its oil-free specification. Make sure to insert tube up to tube end. When inserting a tube, put a liquid like water on the tube, which does not affect the product and the tube. It will improve the smoothness of tube insertion.
