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.
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.
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.
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.
7.Toxic gas is generated when burning fluororesin. Dispose the the product according to the regulations in your area.
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.
Frequently Asked Questions for Fitting Series
Because Push-in fitting seals outside diameter of tube by an elastic-sleeve (rubber seal), there may be a factor causing leak, such as scratches, deformation or jamming of contaminants.
The fittings are designed for pressurized air piping, then they cannot be used for the circuit of gas or liquid which becomes a risk upon leakage, or for an inspection equipment which becomes easily affected by even slight leak.
When disconnecting a tube from push-in fitting, please pull out the tube with sufficiently pushing the release-ring. When you are not used to use push-in fitting, you tend to pull the tube before pushing the release-ring enough so that the lock-claws still bite the tube and it brings difficulties in releasing the tube.
With standard Pisco push-in fittings, the resistance to the fixed durability test is 30 million cycles, and to the sliding movement is 5 million cycles.
Fixed durability test: it is the number of cycles that satisfies air tightness with no-damage, when applying and releasing 0.7MPa air at the frequency of 2 cycles/sec. Dynamic durability test: it is the number of cycles that satisfies the condition of the fixed durability test with oscillation move at frequency of 2 cycles/sec.
Although it may be questioned by durable years (time), since it changes sharply according to an operating condition, it is too difficult to answer in number of years (or hours).
Operating pressure is set by each models. Operating pressure of Standard PISCO Push-in fitting is 1.0 MPa.
Please be sure to check the specifications of each model as the working pressure may change depending on the temperature, such as Tube Fitting PP.
The maximum working pressure stated in the specifications is not the breaking pressure, so even if the maximum working pressure is exceeded, it will not break immediately, but for safety, use it within the specifications. Please note that the warranty does not cover if the product is used in excess of the maximum working pressure.
Except for SUS316 and Brass compression fitting series, elbow fittings of almost all other series can rotate its head. (It is possible to rotate at the connection of metal and resin parts.)
However, rotating the head in this case means that it can turn with fingers, in order to adjust the position of tube output port after screwing in the fitting. If it is necessary to turn the fitting port according to rotation or oscillation of a tube, Rotary Joint or High Rotary Joint built-in ball bearing should be used.
Difference between Standard fitting and Rotary/High-rotary joint
We may be able to prepare combinations of tube diameter and screw size that are not listed in the catalog.
Please contact the nearest sales office for details.
One-touch fittings can be connected as long as the outer diameter of the tube is the same.
Please note that even if the outer diameter of the Barb Fitting and Compression Fitting is the same, they cannot be connected if the inner diameter is different.
Depending on the model types, water can be or cannot be run through. Standard Pisco push-in fitting can be used with water if the conditions are matched. The followings are the conditions to flow water.
1. Make sure to hold the surge pressure, which is temporally raising pressure when closing valve, under the maximum operating pressure.
2. Tap water can be run through. Since other types of water may match our specifications appropriately, please test and evaluate well on actual application in advance.
3. Use Insert-ring (tube inner core retaining pipe made of stainless steel).
Use of Insert-ring is recommended to prevent tube shrinking when using water for a long period of time since tube shrink may cause tube loosing or leaking easily.
Basically it is not possible.
A very soft tube as soft as squashed with fingers is difficult to insert to a push-in fittings. Even it could be inserted, drawing strength is weak and it may be easily slipped through.
Although PISCO Vacuum Tube (UD) is soft that can be squashed with fingers, it can be used for push-in fittings by installing Insert Ring (Pipe-shaped ring made of stainless steel to be installed into inner side of the tube).
Pisco does not offer fittings for rubber hose in principal.
*) However, some Die-temperature control fitting series can be connected to heat-resistant hoses.
PISCO products are designed and developed to be used in both positive and negative (vacuum) pressure environment in the premises. You can rest assured on the use at negative pressure.
Thread part of most PISCO fittings are coated by sealing compound called "Sealock". So you don't have to wind a seal tape around a screw.
However, some products such as SUS316 push-in fitting and PP fitting are not processed by Sealock thus, you should wind up suitable seal tape or apply suitable sealing compound depending on the application.
Even Sealock processing type, the coating may come off after a couple of times of screw-in and then the sealing effect may decrease. Take the same measure as no-Sealock type when needed.
Rather than "Straight type (PC)" which is fixed by fastening hexagonal nut at outer body by a wrench, "Inner hexagonal Straight (POC)" is suited for narrower space because it can be fixed by fastening hexagonal hole at inner diameter side by hexagonal wrench.
Furthermore, mini type is smaller than standard type and more effective.
When low height is required due to fixing spatial reason, we recommend single banjo-type (PH) and hexagonal holed banjo-type (POL) rather than standard elbow-type (PL).
Comparing the heights of ⏀6mmXR1/8 size, standard elbow-type (PL6-01) is 33.55mm, single banjo-type (PH6-01) is 27mm and hexagonal holed banjo-type (POL6-01) is 24mm.
Considering mini-type is also effective measure if same size is available in product line up. (Height of standard elbow-type mini series (PL6-01M) is 22.25mm)
You can connect and disconnect multiple piping at one time by using Connector.
One unit of Connector can connect and disconnect two piping at one time. By combining Connectors in lengthwise and sidewise by connector band, number of piping to be managed at one time will increase.
Light Coupling series is available.

For the size of the hole to be drilled in the panel, refer to the M dimension of the product, and for the thickness of the panel, refer to the A dimension and T dimension.
Example: Bulkhead union PM4
Since the M dimension is M12 x 1, the diameter is 12 mm. But, if the panel hole is made exactly 12 mm, the main body may get caught and it may be difficult to pass through, so please allow a little margin.
The thickness of the panel is dimension A (length of screw part)-(2 x T (thickness of nut)), so in this case 14.8- (2 x 4) = 6.8 mm is the maximum thickness of the panel.
When installing the product in the panel hole, remove the nut once, pass the product body through the hole, and then tighten the nut again to fix the product to the panel.
PISCO uses PTFE (polytetrafluoroethylene).
PTFE is one of the typical fluororesins and is used for water- and oil-repellent coatings on frying pans and the like.
Pure water and extra-pure water have no effect on PISCO product. These waters should be used by a customer's responsibility with paying attentions to the possibilities of spill of part material components, oils applied to a product, or tube additives.
Influence by the use with industrial water is non-predictable. Customers should test and evaluate it by the actual use in advance on their own.
Gray-water and sewer water is not allowed to flow.
EPDM (ethylene‐propylene) rubber is excellent in heat resistance, ozone-proof, solvent resistance, and inorganic chemicals resistance. On the other hand, it does not tolerate general mineral oil, therefore it is not suitable for air circuit which involves oil in the circumstance.
But this is the notice only for general air circuit. When used for water, EPDM is the best suitable rubber material.
Gaskets for metric threads equipped with our products are sold solely in principle. The minimum order quantity is 10 pcs.
Model code is different by the product for which a gasket is used and by size. Please contact the sales office where you purchased the product or Nihon Pasco Overseas Operation Team.

Tighten the resin type screws to the point where they can be stopped by hand, and then use a tool such as a spanner to tighten them two to three turns. If the resin type of the threaded part is used for a long time, the screw may loosen due to creep deformation and a slight amount of leakage may occur. Therefore, perform regular inspection and retightening. If the retightening does not improve, replace it with a new product.
