Advantages
Push-in fitting for rotary section piping in corrosion-resistant environments.
Push-in fitting for swinging and rotating applications made of SUS304 that can be used with water.
*Only water specification (RWL) can be used with water.
Two types are available according to the fluid medium: water specification type (RWL) and air specification type (RAL).
Chemical-resistant and corrosion-resistant PPS, SUS304, etc. are used for the fluid contact parts.
No copper-based metal material is used in airflow path.
Parts that come in with fluids are oil-free.
*Parts not in contact with fluid are not oil-free.
EPDM is used as seal packing material.
Seal packing material: FKM is available as an option.
Seal tape-wrapped threads are available as an option.
*Add "-TP" at the end of the model number.
Specifications

Warnings
* Make sure to follow the instructions below when the fluid medium is water.
Surge pressure must be controlled lower than max. operating pressure when using water 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.
Be sure to place Insert Ring (WR) into the tube edge when using water or liquid as a fluid medium.
As for chemicals, etc., they may vary depending on the conditions of use, so please check the compatibility of our specifications before use.

Detailed Safety Instructions
Warning
1.When fluid leakage occurs, immediately close the valve to stop the fluid and stop using the product. Continued use with fluid leakage may cause a serious incident.
2.Check chemical resistance before using the products, when the fluid medium is chemicals, solvent or mixed gases. Depending on the usage conditions, it may cause damage to the fitting body, disengagement of the tube, or leakage.
3.This product is available in different seal rubber materials, but there is no identification based on seal material. Make sure not to mix the product with other seal materials when opening the packaging. Mixture may cause unexpected situations.
4.PP resin can be deteriorated by being exposed to direct sunlight or ultraviolet rays.
5.Install a filter or strainer on the secondary side of the product to prevent possible contamination of seal material wear debris.
6.Use the product applicable to the fluid to be used. Use of fluids other than those specified may cause damage to the product or leakage.
Caution
1.PPS resin has the property of discoloring when exposed to direct sunlight, fluorescent light, mercury light, and high temperature atmospheres for a long period of time, but discoloration does not affect performance.
2.Note that EPDM (sealing rubber material) is not suitable for piping in general pneumatic circuits due to its inferior resistance to mineral oil-based oils.
3.No sealock (thread sealant) is coated on taper pipe thread, be careful when installing them. When using sealing tape, sealing agent, etc. on the thread, wrap or apply it leaving 1.5 to 2 threads from the thread point.
4.Tube connection into a tube fitting is harder than that of standard spec. due to its oil-free specification. When using, make sure that the tube is inserted all the way to the tube end of the fitting. When inserting a tube, apply a liquid that is not problem to use on the tube surface to improve smoothness of tube connection.
5.The corrosive and dusting properties of the fitting depend on the operating environment. If there is concern about adverse effects on machinery or equipment, evaluate the adoption of the product in accordance with the operating conditions in advance.
6.Do not apply a radial load. It may shorten the service life.
7.For violent oscillations or swings, use polyurethane tubes. Rigid (hard) tubes, such as nylon tubes, can be a source of radial loading.
8.Over-tightening with excessive torque can deform the metal hexagonal column and cause structural rotational failure and leakage.
9.Use clean fluid, as foreign matter on the rotating seal surface may cause a decrease in product life. Remove foreign matter from the piping when piping.
10.Rotational torque may vary depending on the used fluid and operating conditions.
11.Do not leave any liquid residue inside the product when the machine is not operated for a long period of time. It may affect the function and life of the product.
12.This product generates heat by rotation and may become hot depending on the operating pressure and rotation speed. When touching the product, make sure that the temperature has cooled down sufficiently after the rotation is stopped.
13.When using this product in the opposite rotation of the screw tightening direction, the screws may loosen, and periodic maintenance and retightening should be conducted.
