Duotight push fittings

I have just started using Duotight push fittings and will never go back to the old steel barb with crimp clamps. I recently had a clamp fail while force carbonating a minikeg of porter and will now have to repaint my kitchen ceiling...

Advantages of duotight fittings:
 * cheaper
 * easier to use
 * easily reusable
 * create a strong airtight seal


 * come with mfd compatible thread
