Product Detailed Description:

The Male Straight Push-in Fitting (PC type) is a one-touch pneumatic connector with a compact body and male thread connection. Engineered as a direct functional replacement for SMC KQ2H, it delivers identical performance and connection compatibility at significantly lower cost. Tool-free push-in installation and an easy-release collar provide fast, reliable piping from vacuum to 1 MPa, in both PBT plastic and nickel-plated brass versions.

Product Advantages

  • One-touch push-in — insert the tube and it locks instantly; no tools, no tape, no tightening.
  • Direct male thread connection — screws straight into valve / cylinder / manifold ports; compact and space-saving.
  • Dual material options — PBT plastic (lightweight, corrosion-free) and nickel-plated brass (high strength, long life).
  • Wide pressure range — 0–1.0 MPa operating with vacuum support; proof pressure up to 1.5 MPa.
  • Full size range — tube Ø4 / 6 / 8 / 10 / 12 / 14 / 16 mm; threads Rc 1/8" / 1/4" / 3/8" / 1/2" (G / NPT / M on request).
  • Easy release & reusable — press the release collar to disconnect; fitting can be reused many times.
  • Wide tube compatibility — works with nylon, soft nylon and polyurethane tubes.
  • SMC KQ2H-compatible — same dimensions as SMC KQ2H, PISCO PC and Airtac PC fittings; drop-in replacement.
  • Leak-tight reliability — precision seals keep joints tight under pressure and vibration.
  • Factory direct OEM/ODM low MOQ, fast lead time, custom marking and packaging.

Installation and removal oftubing

1.Installalion oftubing

Grasp the tubing and slowly push itinto the fitting until it comes to a stop.The tubing will be locked b

2.Removaloftubing

Push the release button to open the spring gasket so that the tubing can be released

Note: When remove the tubing. mgke sure the pressure in the tubing is Zero

Connection thread tightening method

Use an inner or outerhexagon wrench to tighten the fitting as showin the picture below.

Note:Please refer tothe tables below for the tightening torque and the depth of the thre8d screw-in.

FAQ

Q1. Can plastic One-touch fittings be used when the fluid is water?
A1. Yes, they can (but for industrial use only). The max. operating pressure is 1 MPa including the surge pressure. The operating temperature is 0 to 40°C (no freezing).
Q2. What is the meaning of the “8” and “5/16” engravings on the release button of One-touch fittings?
A2. The release buttons of ø8 mm and ø5/16 inch fittings are shared. However, the size can be identified by the color of the release button (light gray is for the metric size and orange is for the inch size). Similarly, the release buttons of ø4 mm and ø5/32 inch fittings as well as ø3.2 mm and ø1/8 inch fittings also have both sizes engraved.
Q3. .Are there any metric size One-touch fittings with an NPT connection thread?
A3. Consider the use of a metric size uni One-touch fitting.
The chamfered portion of the female thread is used as the seat surface, and the gasket is used for sealing. If using an inch-size tube and an Rc connection thread, inch size uni One-touch fittings are also available.
Q4. For the One-touch fittings, is it possible to switch between metric and inch tubing?
A4. For the straight type fittings, metric/inch conversion fittings are available. Please refer to the variations below.
Note 2) As ø3.2 and ø1/8, ø4 and ø5/32, and ø8 and ø5/16 are shared, different diameter straight type fittings are used.
Note 3) Be sure to confirm that no problems occur before use when using tubing from a manufacturer.
Q5. Is silicon used on the inside of One-touch fittings? (The use of silicon in the device’s mechanisms is problematic for the user.)
A5. Silicon is a chemical element (Si) known for its use as a semiconductor material.
Silicone, on the other hand, is an artificial compound made from silicon (the main component of siloxane).
Is it perhaps silicone that the user sees as a problem?
If so, there is only silicone used in the sealant of One-touch fittings.
However, silicone is not used in the fitting body or parts other than the seal.
Q6.How do I disconnect / maintain it?
A6.Press the release collar evenly and pull the tube out. No routine maintenance needed — keep the fitting clean and make sure the tube end is cut square and fully inserted.
Q7.Does it fit other one-touch systems?
A7.Yes — it connects the same standard nylon / PU tubing used by Festo and other push-in systems. Fittings are interchangeable as long as tube O.D. and thread match.
Q8. Is it interchangeable with SMC KQ2H / PISCO / Airtac PC?
A8.Yes. Same tube sizes, threads and dimensions as SMC KQ2H, PISCO PC and Airtac PC male straight fittings — a drop-in replacement at factory-direct price. Send us your part number and we will match it.
