Build your custom smoke and fume extraction system with hose adapters allowing you to transition between various size hoses.

 This part allows you to connect a 3inch (~76mm) hose to a 4 inch (~101mm) hose for the purpose of smoke and fume extraction of your laser cutter and engraver.

Certain laser enclosures such as the ones from XTOOL and Creality typically include some length of 3 inch hose as well as a 3 inch hose flange on the side of the enclosure. It is common practice to attach an inline duct fan to the enclosure to draw out the fumes. These duct fans are most commonly found with 4 inch inlet/outlets. Therefore to connect the enclosure and the inline fan you must splice together a 3 inch hose (from the enclosure) to a 4 inch hose (to the inline fan). This part will make it possible.

If you are looking for examples of inline fans that are commonly used for this application, see the links below.

 What is included:

• QTY: 1 Plastic Adapter (color: BLACK)
