Welding end cap tube dia 10mm 1/2" nut

On this product page you will find a brass welding cap. These welding caps are soldered to the ends of copper tubes in combination with a welding nut. This round surface seals off when the nut it tightened. The brass material compresses and this seals off the valve. At some point this seal will leak.

This is the biggest size of welding fitting you can find for espresso machines. This type of fitting can be found on the water level of a Faema E61 espresso machine. But also on variety of other situations.

Even though this is one of the biggest sizes of welding caps, the tube size isn’t the biggest. The type of copper tube used is a 10mm tube, with a wall thickness of 1mm. The type of welding fitting used in combination with this solder fitting is one with a female ½” BSP-G thread. With a central hole of 15mm.
