Fitting

Tube Fitting Standard Series

RoHS2 Compliant

The Tube Fitting comes in a wide variety of models to meet all your needs in pneumatic piping.
Water is admitted conditionally.

Resin
  • PBT is used for the main resin parts. PBT: A standard resin material that is ideal for general environments.
Metal
  • Brass with electroless nickel plating is used for the main metal parts.
Seal rubber
  • NBR is used for the seal rubber material. NBR: A material generally used as a sealing material. Please note that it is inferior in ozone resistance.

Corresponding product

  • Fluorine grease is used as grease, and the product is packaged in a clean room after cleaning with clean air.
  • After vacuum ultrasonic cleaning with HFE (hydro fluoro ether) in a clean room, deaeration packaging is performed.

Options

  • 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

The Tube Fitting comes in a wide variety of models to meet all your needs in pneumatic piping.
Water is admitted conditionally.

High performance / high quality

The lock-claws grips circumference of the tube evenly.
Feeling as good as new, even after many years.
PISCO's uniquely shaped elastic sleeve shuts out air leaks.

Industry leading wide variety of models.

Various sizes of unequal union type makes it possible to handle with just one fitting, although two or more fittings are used before.
It reduces the amount of fitting used and enables cost and space saving.

Even after installation, the direction of the tubing can be changed freely.

Centralized piping is possible.

Triple type (PKD, PKG, PKJ) and Twin Triple type (PKVD, PKVG) realize compact centralized piping.

Clean-room Package, best suitable for piping in cleanroom, is available. (Optional)

Fluorine grease is applied and washed by clean air, then packed in ISO class 6 cleanroom.

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

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.

Caution

1.To adjust the direction of the elbow fitting after fixing PML (Bulkhead Union Elbow) type, turn it in the clock-wise (right) direction.

2.Attach a rubber washer to the aluminum nut side when installing PML (Bulkhead Union Elbow) type. The bulkhead parts may be loosened or the rubber washer may deform if attaching it to the hexagonal side.
