Partner stoves are built to last a life time or more. As with any quality piece of equipment, it may need maintenance or repairs.
The stove that came as a part of my Kantz kitchen box showed problems this last trip, the fuel hose fitting attached to the stove had started leaking. This led me to investigate replacement parts and I found that Partner sells a parts kit that includes all the parts from needle valves to rubber o-rings. The kit also includes a great troubleshooting guide.
I ordered up one of these kits that will now be a part of my kitchen box should I have any other problems with my stove.
