Air Pump (DIN7756) to Garden Hose Blow-Out Fitting

This adapter connects a standard automotive tire valve (DIN 7756 VG8 thread) to a 3/4" garden hose fitting, such as a Gardena-compatible connector. It allows you to use a tire inflator or air compressor to blow out water from hoses, which is especially useful for:

• Winterizing irrigation systems or outdoor garden hoses
• Draining hoses used for camping (e.g., portable showers or water fill lines)
• Preventing water freeze damage during cold seasons
• Drying out gear before storage

Tested with:

• Xiaomi air pump (screw-on valve connection)
• Makita DMP180 / Bosch UniversalPump 18V (quick-connect fitting)

Print recommendations:

• Works with PLA, but PETG is strongly recommended for better durability and pressure resistance
• Take extra care with the DIN 7756 VG8 end of the adapter—it’s more fragile and can snap if overtightened or stressed

Additional components:

• Gardena compatible G ¾" adapter
  You can either buy one (e.g., https://www.gardena.com/de/produkte/bewaesserung/ogs/hahnverbinder/970522301.html or print one yourself (models can be found plenty).
