Lord Geordie Posted November 12, 2017 Report Share Posted November 12, 2017 I only know it as a Jura coupling. But assume that's because it's used in Jura coffee machines. I also assume (having seen them in more than just coffee machines) that they have a technical name? They would perhaps be used in hydraulics? Compressed air? High pressure systems. thanks in advance for any input. Quote Link to comment Share on other sites More sharing options...
davewh100 Posted November 12, 2017 Report Share Posted November 12, 2017 (edited) hi martin there very similar to the ones used in some of gaggia machines i know how it works is this the fault on yours ? normally these are a three way valve dave Edited November 12, 2017 by davewh100 Quote Link to comment Share on other sites More sharing options...
Mice! Posted November 13, 2017 Report Share Posted November 13, 2017 Doesn't look heavy duty enough to handle compressed air to me. Quote Link to comment Share on other sites More sharing options...
Lord Geordie Posted November 13, 2017 Author Report Share Posted November 13, 2017 It's a connector to handle 15 bar of pressure. I have seen similar used on air systems to operate solonoids on conveyor systems, and actuators on hoppers. Dave! It's not a valve! It's a straight through coupling! The one in my machine cracked. I saw a few with filters fitted. They come in a variety of guises. Straight, elbow, Y, F, T. I found a couple of suppliers "mainly abroad" but wanted to try and find a sensible price for what it is. They are simply mounded parts and will cost pence to produce! And due to size, I would assume a standard letter to post out. But the Ines I found here equate to around £7 + without the spring clips. i just think that is a bit of a silly price and wanted to see if I could find a supplier of the same part, though not a coffee machine parts company. Its hard to believe eve so many people bin their machines when these fracture! It's such a simple part to replace. It took me 3 mins to take the machine apart, and 30 seconds to find the fault. Hopefully I will find a stockist and can then get it back up and running again. It may sound tight not wanting to pay £7 but the machine was only £20 when I bought it.

Chris B123 Posted November 13, 2017 Report Share Posted November 13, 2017 If the pipe is a standard size, 6mm 8mm or 10mm try plumbing supplies, Quote Link to comment Share on other sites More sharing options...

Lord Geordie Posted November 14, 2017 Author Report Share Posted November 14, 2017 Might have it sorted! Just found a L shaped one which looks to be right from a FRANKE machine. They were £1.65 so ordered two just incase the other one in the machine goes too as there is one feed in, and one out. Hopefully here on Thursday so can crack on and get the machine back together Quote Link to comment Share on other sites More sharing options...
