Tube Fitting Stainless SUS303 like Corrosivity Series

RoHS2 Compliant

This tube fitting serves best where strength is required or corrosive atmosphere.

Resin
  • PBT is used for the main resin parts. PBT: A standard resin material that is ideal for general environments.
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.
  • No copper-based metallic material is used in flow paths
  • HNBR or FKM is used for the seal rubber material. *Some products are only compatible in the flow path.

Advantages

This tube fitting serves best where strength is required or corrosive atmosphere.

Made of SUS303 equivalent, which is resistant to corrosion.

HNBR seal is used for the industries where low level ozone resistance is required.

Clean wash specification, best suitable for various production processes where foreign particles and oil are not welcome, is prepared. (Optional)

Deaeration package after vacuum ultrasonic cleaning by HFE (hydrofluoroether) is carried out in the cleanroom.

Detailed Safety Instructions

Warning

1.When the fluid medium is water, 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 can not be used in case a fluid medium is a chemical. For use with chemicals, please refer to "Chemical-proof properties" in PISCO website and select a suitable product.

Caution

1.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.
