Fitting

All Brass Compression Fitting

RoHS2 Compliant

By using special brass in the main metal body, this product line has achieved the high resistant performance against water.
Best suitable for Auto Industry and Thermal Control for mold tooling.

Metal
  • Brass is used for the main metal parts.
  • HNBR or FKM is used for the seal rubber material. *Some products are only compatible in the flow path.
  • No lubrication is used during assembly.

Advantages

By using special brass in the main metal body, this product line has achieved the high resistant performance against water.
Best suitable for Auto Industry and Thermal Control for mold tooling.

It does not require connecting sleeve, therefore, no more need to worry about installing or missing sleeves.

Specifications

Fluid medium Air, Water, Others such as chemicals (Conditional*1)
Max. operating pressure Depending on max.operating pressure of tube
Max. vacuum -101.3kPa
Operating temp. range Depending on operating temp. range of tube(No freezing)*2

Warnings

*1. 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.

The specification above may not be applied when using other fluid medium except air and water. Make sure to use PISCO products after verifying their suitability on the user side.

Warnings

*2. Operating temp. range follows the specification of the tube. The operation in a high temperature environment may cause damage to the products when they receive an excessive load.

Warnings

*3. Because of the fitting's structure, the performance decreases if soft tube is inserted. Be sure to confirm the practical effect with a using tube before actual operation.

Detailed Safety Instructions

Warning

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

Caution

1.Taper thread is not coated with Sealock. When coating the thread with seal tape or sealant, do not coat 1.5 to 2 screw ridges from the tip of the thread.

2.The level of corrosion of the fittings varies by operating conditions. In case there is a possibility of negative effects on machines or facilities due to these conditions, evaluate the suitability of the products in advance.

3.Special brass without surface treatment has a characteristic of color change by being exposed to high humidity or by sebum when touched.

4.In case of using non-PISCO brand tubes, make sure the tolerance of the outer / inner tube diameter is within the limits of the following table.
