دراجة نارية سيارة مخلب الفرامل النازف خرطوم صمام اتجاه واحد أنبوب أدوات النزيف عدة

The diameter is 4mm on one side (other side is 5mm), how do you put that on a brake nipple that has a diameter of 7mm. I like the idea of ​​the check valve. But with the small diameter of the hose, it doesn't fit on my motorcycle or my quad.

Good value for money. As in description. To be tested on the brake calipers x to test the seal of the membrane. Velicey shipping

Nicely engineered, haven't used it as yet. Very good service and delivery time. Many thanks.

OK no information on what to do with it thanks very much for your help again
