SUS Rapid Pneumatic fittings

Also called Rapid fittings/ Push-on fittings/ Rapid screw fittings

Made in Taiwan | Stainless Steel 304 & 316 Materials

Rapid Pneumatic fittings are one of the most extensive solutions for pneumatic tubing.
It’s a common and popular connection that takes advantage of extreme safety and is leakproof.
The special bulge design ensures the soft tubes be mounted tightly and simply fixed by the hexagon nut, moreover, it also can be easily dismounted or exchanged conveniently.
They do not have internal O-rings, so it is compatible with harsh operating conditions such as high temperature, high pressure up to 45Kgf/cm2, and specific chemical fluids (like Hydrogen peroxide). We could also say the working pressures and temperatures depend on the tube itself thanks to stainless material.
It is definitely the most reliable way for soft tubes such as Polyurethane(PU), Polyethylene(PE), Polyamide (Nylon), Polypropylene (PP) and Polyvinyl chloride(PVC).


1. Chemical resistance
High level of corrosion resistance and transfer the fluid in a clean manner. Able to adapt in alkali, acid, and almost all of the chemicals.

2. User friendly
Easy to install manually; all you need is a wrench.

3. Safety
Stainless fitting comes with better pressure & temperature resistance than most tubes to make reliable operation.

4. Reuse
Able to reuse, and easy to uninstall when replacing a tube.


Different varieties of flexible tubing including materials of Teflon, PU, Nylon … etc.

Installation Instructions

  1. Make sure the tube is cut neatly before installation.
    Mount the bulge into the tube until its cross-section touches the surface of the body.
  1. Fasten the nut until the nut hole is aligned with position A.
    Do not over-torqued or the tube might be broken.
