Suitable for use with nylon, soft nylon and urethane. Large retaining force.The chuck provides a secure bite, while retaining force is increased.
Can be used for a wide range of pressures from a low vacuum up to a pressure of 1 MPa.The use of a special profile ensures sealing and reduces resistance when the tube is inserted.
Light force for removalWhen the fitting is removed from the tubing, the chuck and collet are released, thus preventing them from biting into the tube to an unnecessary degree. Unique shape allows easy tube release.
Effective when piping in a confined space.• The body and the threaded portion can rotate (for positioning to some extent).
• Stud is electroless nickel plated.• Standard with preapplied sealant for R 1/8 thread
Optimum piping in less space with 20% reduction of the outside diameter.Thread with sealant is standard.Copper-free specifications(With electroless nickel plated.)Possible to use in vacuum to –100 kPa.
Note 1) Soft nylon tubing is not compatible with water.
Note 2) The surge pressure must be under the maximum operating pressure. Note 3) Do not use the fittings with a leak tester or for vacuum retention because they are not
guaranteed for zero leakage.
Made to Order (Refer to page 26 for details.)

Precautions
1. Please do not attach metal rods or metal pipes. Metal rods or pipes cannot be secured and the fittings will shoot out. Also, if tubes are attached after metal rods or pipes have been attached, the tubes will not hold and may come loose.
1. While pushing down on the rim of the re-lease button, pull out the tube in the direc-tion of the arrow (see illustration.)The release button can also be pushed down with a flat-head screwdriver. How-ever, be careful not to break or damage the release button.
2. To reuse the released tube, cut off the damaged portion of the tube.
Installation and Removal of One-touch Mini FittingsCaution
1. After tightening by hand, tighten further about 1/6 of a turn with a tightening tool.

Internal hex. allows thread connection by using an allen wrench for confined spaces.
Use to connect tubes through a panel.
Universal male elbow allows thread connection by using a socket wrench for confined spaces.
Use to pipe in the same direction from female thread. Most general style.
Use to change by 90° in a tube fetching direction from One-touch fittings.
Use to branch line in the same direction.
Use to pipe from male thread such as pressure gauge.
Use to change by 90° in a tube fetching direction from One-touch fittings and to size down.
Use to branch line with size down in the same direction.
Use to connect tubes in the same direction.
Use to branch line from female thread in both 90° directions.
Use to branch line in the same direction from One-touch fittings.
Use to connect different sized tubes.
Use to connect tubes in both 90° directions.
Use to branch line with size down in the same direction from One-touch fittings.
Use to pipe at right angles to female thread. Most general style.
Use to connect tubes with size down in both 90° directions.
Use to branch line in the same direction from female thread.
Use to connect tubes at right angles.
Use to branch line in the same direction from female thread and in 90° direction.
Use to change size of One-touch fittings.
Installation of tubing1. Cut the tube perpendicularly, using
caution not to damage its surface. (Use tube cutter TK-1, 2 or 3. Do not cut the tube with cutting pliers, nippers, scissors, etc.)
2. Grasp the tube, then slowly push it until it comes to a stop.
3. Then, pull it back gently to make sure that it does not come out.

Inch-size Miniature One-touch Fittings
Series KJApplicable Tubing : ø1/8”, ø5/32”, ø1/4”Connection Thread : 10-32 UNF, NPT 1/16, NPT 1/8
Suitable for use with nylon, soft nylon and urethane.Large retaining force.The chuck provides a secure bite, while retaining force is increased.
Can be used for a wide range of pressures from a low vacuum up to a pressure of 1 MPa.The use of a special profile ensures sealing and reduces resistance when the tube is inserted.
Light force for removalWhen the fitting is removed from the tubing, the chuck and collet are released, thus preventing them from biting into the tube to an unnecessary degree.Unique shape allows easy tube release.
Effective when piping in a confined space.• The body and the threaded portion can
rotate (for positioning to some extent).• Stud is electroless nickel plated.• NPT 1/16, NPT 1/8 with sealant for thread.
Optimum piping in less space with 20% reduction of the outsideThread with sealant is standard.Copper-free specifications (Electroless nickel plated)Possible to use from vacuum –100 kPa
ø , ø , ø 1 45 321 8
Note 1) Soft nylon tubing is not compatible with water.
Note 2) The surge pressure must be under the maximum operating pressure. Note 3) Do not use the fittings with a leak tester or for vacuum retention because they are not
guaranteed for zero leakage.
Operating pressure range (3)

Caution Installation and Removal of One-touch Mini Fittings
Caution
PrecautionsBe sure to read before handling.Refer to front matters 58 and 59 for Safety Instructions and pages 13 to 16 for Fittings and Tubing Precautions.
Internal hex. allows thread connection by using an allen wrench for confined spaces.
Use to connect tubes through a panel.
Basically, it is used together with male elbow.Different point is that it is used for fittings to avoid from interfering with each other by making the piping two-level.
Use to pipe in the same direction from female thread.Most general style.
Use to change by 90° in a tube fetching direction from One-touch fittings.
Use to branch line in the same direction.
Use to pipe from male thread such as pressure gauge.
Use to change by 90° in tube fetching direction from One-touch fittings and to size down.
Use to branch line with size down in the same direction.
Use to connect tubes in the same direction.
Use to branch line from female thread in both 90° directions.
Use to branch line in the same direction from One-touch fittings.
Use to connect different sized tubes.
Use to connect tubes in both 90° directions.
Use to branch line with size down in the same direction from One-touch fittings.
Use to pipe at right angles to female thread.Most general styles.
Use to connect tubes with size down in both 90° directions.
Use to branch line in the same direction from female thread.
Use to connect tubes at right angles.
Use to branch line in the same direction from female thread and in 90° direction.
Use to size down One-touch fittings.
1.
2.
3.
Installing of tubeCut the tube perpendicularly, using caution not to damage its surface. (Use tube cutter “TK-1”, “TK-2” or “TK-3”. Do not cut the tube with cutting pliers, nippers, scissors, etc.)Grasp the tube, then slowly push it until it comes to a stop.Then, pull it back gently to make sure that it does not come out.
1. Please do not attach metal rods or metal pipes. Metal rods or pipes cannot be secured and the fittings will shoot out. Also, if tubes are attached after metal rods or pipes have been attached, the tubes will not hold and may come loose.
1. While pushing down on the rim of the re-lease button, pull out the tube in the direc-tion of the arrow. (See illustration.)The release button can also be pushed down with a flat-head screwdriver. How-ever, be careful not to break or damage the release button.
2. To reuse the released tube, cut off the damaged portion of the tube.
