    A definite requirement if replacing the outlet connection as invariably the o ring is lost or damaged on removal of the outlet nozzle.

    The O-ring was not made of thick enough material to form a seal, and it was of no use to me although it was expensive. Instead, I bought a much less expensive Draper's attachment and used the ring out of it.

    The O Ring supplied was perfect for its intended use. The overall cost, (pp inclusive) was definitely not value for money

  • Q How does the 'O' ring actually fit? 1 Answer

    There does not seem to be an obvious groove for the @o@ ring to fit into. I messed the current one by it going into the locking slot. Do you have a diagram that shows its position. Your video doesn't really help as it doesn't show the 'O'ring in place or how to refit the assembly.

  • Q loss of water pressure 1 Answer

    I have a Karcher 310. Yesterday the motor made a small "pop" sound and the water pressure dropped, and water started coming thro the vents in the back of the machine (and still thro the lance). Could you please advise what the problem is and what part I will need to hopefully fix this problem. The motor is still working.

      Hi Deckie, I'm going to refer you to the instruction manual for your model, which can be viewed here: http://www.espares.co.uk/datastore/ProductManuals/561741.pdf If you go to page 18 of the document, it has a troubleshooting guide with ways you can diagnose the cause of your problem.
