Caution
1. When inserting an ultra-soft tube into a push-in fitting, make sure to place an Insert Ring into the tubing end. There is a risk of causing
the escape of tube and a fluid leakage without using an Insert Ring.
2. The product incorporating NBR as seal rubber material has a risk of malfunction caused by ozone crack. Ozone exists in high
concentrations in static elimination air, clean-room, and near the high-voltage motors, etc. As a countermeasure, material change from
NBR to HNBR or FKM is necessary. Consult with PISCO for more information.
3. In case of using non-PISCO brand tubes, make sure the tolerance of the outer tube diameter needs to be within the limits of Table 1.

4-1. Instructions for Tube Installation (in case of push-in fitting)
①
.Make sure that tubes need to be cut at right angle without a scratch on the tube surface and deformation.
②
.When installing a tube, the tube needs to be inserted fully into the push-in fitting until the tube stops up to the tubing end of the
fitting as the figure shown below. Otherwise, there is a risk of becoming leakage.
③
.After installing the tube, make sure it is inserted properly and not to be escaped by pulling it moderately.
* When installing tubes, Lock-claws may be hardly visible in the hole when observed from the front face of the release-ring. But it
does not mean the tube is surely escape. Major causes of the tube escape are 1: shear drop of the lock-claws edge, and 2: the
problem of tube diameter (usually small). Therefore, follow the above instructions from
①
to
③
, even lock-claws is hardly visible.
4-2. Instructions for Tube Installation (in case of compression fitting)
①
.Make sure that tubes need to be cut at right angle without a scratch on inside and outside surfaces of the tube.
②
.Install the tube through the cap nut onto till the end of barb. Then tighten the cap nut, having the tube through, by using spanner
on the hexagonal flat.
③.
Tightening the cap nut with a recommended tightening torque referencing the Table-2.
* To prevent co-rotation of tube when tightening the cap nut, hold the tube while tightening.
④.
Make sure that the cap nut touches the fitting body. If not, remove the nut and pull out the tube. Then start it over again from
①
.
⑤.
Make sure to confirm no leakage after tightening.
⑥.
After installing the tube, make sure it is installed properly and not to be escaped by pulling it moderately.

5-1. Instruction of Tube Release (in case of push-in fitting)
①
.Make sure there is no air pressure inside of the tube, before releasing it.
②
.Push the release-ring of the fitting deeply and evenly to pull out the tube toward oneself. By insufficient pushing of the release-
ring, the tube may not be pulled out or damaged by scratch, and tube shaving may remain inside of the fitting.
5-2. Instruction of Tube Removal (in case of compression fitting)
①
.Make sure there is no air pressure inside of the tube, before releasing it.
②
.Remove the cap nut using the appropriate tool on the hexagonal flat. Then remove the tube.

Warning
1. Do not use PISCO products under the following conditions.
①
.Beyond the published specifications and conditions in the catalog.
②
.Under the direct sunshine or outdoor.
③
.Excessive vibrations and impacts.
④
.Exposure / adhere to corrosive gas, inflammable gas, chemicals, seawater, water and vapor.
* It can be used depending on the product in the above conditions, refer to each specification and condition in the catalog.
2. Do not disassemble or modify that related to the performance, function, and basic structure of the product.
3. Do not touch the release-ring of push-in fitting while compressed air is supplying. The lock may be released by the contact, and tube may
slip out.
4. Avoid stress on PISCO products, such as excessive stretching, twisting and bending. There is a risk of causing damage to the products.
5. Turn off the power supplying to PISCO products, and make sure there is no residual air pressure in the pipes and equipment before
maintenance. Follow the instructions below in order to ensure safety.
①
.Make sure the safety of all systems related to PISCO products before maintenance.
②
.Restart of operation after maintenance shall be proceeded with cautions after ensuring safety of the system by preventive measures
against unexpected movements of machines and devices that are using pneumatic apparatuses.
③
.Keep enough spaces for maintenance when designing a circuit.
