## PFA tube fusion welding fittings

![PFA tube fusion welding fittings](https://en.kitzsct.com/hubfs/images/products/highlight/9/img_9_001_en.png)

These fusion welding fittings support prevention of the leaks caused by higher temperatures and concentrations of chemical liquid in semiconductor manufacturing process piping.

### Features

#### No leakage, clean, lightweight and compact

No need for retightening and no concerns about leakage, since the end faces of the fitting and tube are completely sealed by butt fusion welding.

- The fusion welded parts have higher strength than the tube and will not break or rupture.
- There is no sliding part on the inner surface of the connection, providing excellent particle characteristics.
- High heat resistance is achieved, preventing loosening or leakage due to thermal cycling.

#### Enables easy shortest-distance fusion welding

The newly equipped boss enables fusion welding by customers even when dimensions permit no clamping allowance, enabling compact piping layouts.   
*The shortest-distance cutting jig and shortest-distance fusion welding clamp jig for PMW fusion welding machine are required.   
*Since 1 1/2 has no boss, shortest-distance fusion welding is not possible.

#### Sleeve can be press-fit directly

With a longer tube, a sleeve press-fit type fitting can be directly installed, enabling shorter installation time and more compact piping design. Clamping the boss with a press-fit jig stabilizes the orientation while press-fitting, making it easy to insert the sleeve straight and preventing installation errors.   
* The press-fit jig is to be prepared by the customer.
