Seal O-Ring Kit for Saeco/Philips/Gaggia Coffee Machines - Food Grade Silicone Gasket Set for Boiler Outlet, Brew Unit, Nozzle - 8 PCS Maintenance Kit.

This is the perfect set of o rings for my coffee maker. I first noticed I needed to change these out as my maker seemed to be dispensing less coffee, yet the bottom bin would fill sooner than it had been. What it was were the o rings in my machine were wearing out - causing a loss in pressure, plus a slight leak around them. They are very easy to replace - especially when having a set like this (versus trying to find the multiple sizes you need). This set are the correct sizes, which the thickness is very important to keep it the same when swapping them out. I noticed I need to change these every 18 months or so (I use my machine a lot - probably 6-8 coffees a day). I would recommend purchasing a couple sets - so when you then use one, have another ready just in case.

These are OEM-level replacement o-rings. If you own a Saeco (or similar) espresso machine you will need replacement rings for (1) the tamper cylinder and (2) the steam valve at some point in your ownership. These work perfectly. They are dimensionally correct, and the price is reasonable. There isn't much more to say for a maintenance part.I recommend this kit.
