Specifications

Fluid medium Liquid (Conditional*1)
Max. operating pressure 0.7MPa(at0~60℃)*2
Operating temp. range Impact-ring material PVDF 0~150℃(No freezing)
Operating temp. range Impact-ring material PPS 0~200℃(No freezing)*3

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, depending on the kind of chemicals used as fluid medium. Make sure to use PISCO products after verifying their suitability on the user side.

Warnings

*2. When operating temp. exceeds 60°C, refer to the following chart "Relation of Operating Temp. & Max. Operating Pressure 1"

Warnings

*3. Impact-ring made of PVDF (Max. operating temp. : 150°C) is equipped with fitting as standard. PPS impact-ring (Max. operating temp. : 200°C) is required when using fittings in high temp. exceeding 150°C). Check the tube dia. and order applicable impact-ring as well.

Construction

Advantages

Detailed Safety Instructions

Warning

1.Make sure to follow the instructions in our web catalog or instructions manual for the installation, retorquing and reinstallation of the products. Improper installation or tightening may cause accidents like a fluid leakage or a piping coming off.

2.Do not retorque the products while pressure is supplied or under high temperature. It may cause damage or deformation of the products, leading to a fluid spouting. Make sure to lower the temperature to normal, and set the pressure to zero before retorquing.

3.Make sure to use fittings within the range of the specifications. Otherwise accidents like a fluid leakage or a piping coming-off may be caused.

4.Max. operating pressure of this products varies depending on the operating temperature. Make sure to check the “Relation of Operating Temp. & Max. Operating Pressure” in the specifications before the usage and follow it.

5.Since the fitting is made of resin, avoid any tensile force and bending force in / after installing it. Otherwise, there is a risk of causing damage or deformation of the product, resulting a fluid leakage.

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

7.Do not use this series under the condition with vibration or physical impact. These may cause damage to the products, the escape of tubes and a fluid leakage.

Caution

1.Do not use Pisco’s fluororesin equipment, combined with any other parts than this series. Otherwise accidents like a fluid leakage or a piping coming off may be caused.

2.Take safety measures such as providing a protection cover on piping and fitting to avoid burn when the liquid in piping exceeds 70°C.

3.Make sure to use Pisco’s flaring tool to flare tubes. Otherwise accidents like a fluid leakage may be caused.

4.Pay attention not to get burned when flaring tubes. The parts get hot.

5.Make sure the room is well ventilated when flaring tubes. Toxic gas may be generated if excessively heated.

6.Make sure to dispose liquid in a product and wash it before discarding the product. Unwashed fitting waste with toxic, flammable or corrosive liquid can be dangerous.

7.Toxic gas is generated when burning fluororesin. Dispose the the product according to the regulations in your area.

8.Contact us when using gas as fluid medium. Basically Pisco’s fluororesin equipment is designated for liquid.

9.Make sure that the impact-ring is in the right position after piping. Piping without impact-ring is dangerous, causing accidents like a fluid leakage or a piping coming off.

10.Make sure to use impact-ring for high temperature when the liquid in piping exceeds 150°C. The impact-ring equipped with a fitting as standard will cause a fluid leakage or a piping coming off on 150°C or higher.

11.When retorquing is necessary, due to a leakage from tube inserting parts, make sure the liquid temperature is normal, and make the pressure zero before retorquing. Tighten the union nut with a special wrench by 1/4 turns and observe the progress. Be noted that the liquid still may ooze out after retorquing (even after the leakage stops) for a while, since some liquid remains inside the union nut.

13.After the initial tightening of the union nut and taper pipe thread, the torque is reduced, normally within 24hours, due to the characteristics of the resin. Therefore, retorquing after 24hours is effective to ensure the long-term stable sealability. When a heat cycle is applied to the fitting, retorquing at low temperature after the first heat cycle is recommended.

16.Take safety measures such as providing a protection cover if there is a risk of causing damages or fire on machine / facilities by a fluid leakage.

17.Corrosiveness of a product and its ion elution to fluid medium depend on the operating environment. If they might adversely affect the machine and equipment, evaluate and examine the product based on the actual usage condition prior to the product adoption.

18.When metal type flaring tool (F-JA-□-T) and the corresponding tool base (F-BA-3), metal ion may adhere to tube if it touches the tools.
