the yellow plug and spindle that it slides over in the gun is slightly smaller diameter on the new T Racer patio cleaner and its extensions than the spindle on my existing K4 full control and its attachments had to desrtoy the yellow plug to get it out agian

Mines leaking from the Trigger gun where the accessories connect. It leaks with every accessorie so not the Orings in this video. Is there an O ring in the gun itself?

I've just destroyed two new o-rings trying to get them to fit underneath the yellow thing. After an hour I've given up. Putting the o-ring on the yellow bit is easy; trying to push it in is impossible without twisting and breaking the ring.

details of the inside of the nozzle please

Do you know why my yellow bit after twisting keeps on coming out and how would you fix it??

[moinush]

Can you please give idea ... Whats the internal diameter size of the o ring in mm?

The yellow plug on my k4 keeps getting stuck in the trigger when I swap from the patio cleaner head to the normal lance. Any suggestions how to fix this?
