Specifications

Specifications of MCT (Open to air)

Outside of Tube Condition 1, Open to air
Fluid medium Liquid (Conditional*1)
Max. operating pressure 0.7MPa(at0~60℃ within the range of Max. operating pressure of Tube)*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. For condition 1, 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

Suitable for chemical liquid piping in semiconductor manufacturing process.

High pull-out strength and sealability are realized.

An impact-ring holds the tube firmly.

Easy control of union nut tightening.

A click gauge is incorporated for making an easy check that the union nut is firmly tightened.

Straight Through type, in which the liquid touches only with the tube, is also available.

The body has a through hold equals to the tube O.D.

Clean washing + Clean packaging.

Equivalent to ISO class 6.

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.

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.

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.

12.A leakage from taper pipe thread parts due to “creep phenomenon” which is particular to resin may occur. Check the tightening condition periodically and re-torque the thread in case of leaks.

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.

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

15.Tighten taper thread by hand until it stops, then use a wrench to tighten it about 1.5 to 2.5 more turns. Excessive tightening may break the thread part. Inadequate tightening may cause a loosened thread or a fluid leakage.

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.
