I think those tubes are the same size as the ones in the Breville dual boiler. There should be red (silicone) #007 o rings in there that seal the tube to the elbow. If you replace that there is a good chance that you'll be back in business.

I used to have one of these machines and I think the other end of that elbow seals with an o ring too. If so, replace it too.

Good luck. ... 991&sr=8-3

The machine is working well and making great coffee. Very happy! Easy to install the part as well.

I just wanted to thank you for your awesome cure for that leaky plastic elbow. I purchased the part you mentioned (I ordered two from the UK - just in case). It did leak the first time, but that was my fault for not pulling out the sleeve on the fitting. A minor correction and all was great except for my machine kept flashing filter cup size. That took awhile to troubleshoot until I realized that I forgot to twist the hopper in place to activate the magnetic switch LOL! Remember that one people. Anyways got espresso again. Wife is extremely happy. I just can't take the credit. That belongs to you. Thanks again!!!

Don't normally post on these things, but I think link was the perfect fix for the crappy plastic elbow. Mine has completely degraded internally, so I purchased the stainless steel 4mm to 1/8 bspp elbow. It's all fitted please see photos attached. Thank you for putting the effort in to post on these forums, makes life easy for people like me.

I had exactly the same problem with the elbow joint and have replaced with the metal one, it was a great fix. However does anyone know of a replacement part of the plastic tubing (I belive called the elbow tube) coming out of the solenoid valve? Mine it leaking and I wanted to see if that could be replaced with a metal part too. I have hopefully included a photo of the part

Hi ash24

It is amazing you could fit that one in, would you mind posting the link where I could be able to get that metal elbow.

Really appreciate it, happy new year to everyone.

Unfortunately, in my case I have different solenoid base, so I can't use this metallic elbow.
Any ideas? Thanks

Hi, have you found a solution to the leak from the vertical tube coming out of the solinoid? Hard to find a replacement part. Just wonder if there is a way to seal it tighter. The tube on my machine looks fine, really just like your in the picture.

Really interesting this upgade!
I've not investigated my leak fully yet but the horizontal white plastic T pipe between the Solonoids leak a little, I only purchased machine this week secondhand, so I'm new to this particular model. I've ordered some silicone o-rings in case it's that simple but reading through this it could be the plastic itself.

I was wondering if this is a replaceable pipe if needed, even with a metal one like the elbows above?

Also I have steam condensation in the pressure gauge glass, pipes to it are all tight and minor, it's annoying to see. How on earth do I get to the rear screws/nut holding it in the control panel? I can't work out how to lift the control panel out to gain access.

Wondering if there are comparable gauges with other brands, I can't seem to see a sage one reasonable priced in the UK. Sage seem to have all their parts tightly controlled.

Thank you.
