Junkosha Fittings

Instant Fitting

The compact and simplified design results in significant reductions of time spent on piping work. Junkosha offers highly reliable fittings that are compatible with both nylon tubing and urethane tubing. 
M series (miniature type) and W series (spatter-resistant type) are both faster and more convenient for piping work compared to more general fittings.

Features

- All metal components come with electroless nickel plating
- Different color options available for screws to simplify identification
- Easily set the body position to match the tube extraction direction
- Tubing grip rotates smoothly inside fitting to prevent tube shearing
- Optional speed controller fittings allow for adjustment of flow rate

Use

- General air pressure piping
- Piping for spot welding robotics
