Worcester Small Boiler Filling Loop Key 871611045910

I don't know why we had a key one fitted when Worcester did the key less filter (looking at you British gas)Broke it trying to refill, ordered a new one perfect replacement.Note though, use some vaseline or wd40 so don't break it again.

Works a treat. The rubber rings on my old one had decided to expand to a point where it just would not fit! So get one of these if you are having trouble, do not try and force a key into your boiler!!! The key should slip in effortlessly.

Does what it’s supposed to do. I just question worchesters design. It’s not easy or user friendly to top up the water.

Can't really go wrong as it is the key for the job. However, this is my second replacement due to them being a really tight fit when removing. I suggest a bit of lubricant (Vaseline or soap) on the seals before sliding it into the loop hole.

My last one the rubber rings expanded and made the key unusable. This worked fine.

Needed a replacement as other one broke

The original key had been damaged beyond repair. The replacement was perfect and I would recommend this part be purchased as a standby.

Very nice
