Cheap after market parts are not always a good choice.
At first I bought a cheap Chinese made aftermarket end cap for about $29. I installed it and started bleeding the system. To my surprise the new seals started leaking immediately. I had to reorder a new one, this time the OEM version for $110. I installed the OEM cap, no leaks. I know it’s a quality OEM part however I think it’s overpriced for a small piece of aluminum with some seals.
The seals from this supplier seem to be made of quality material and are an exact fit. There are cheaper ones available but I found out the hard way the don’t seal properly
Easy to fit, and my leak is gone. Impressed that it came with quality grease on the threads to ensure a good seal and I didn't have to buy the correct grease. I already had the spanner so make sure you have it if you buy these seals.
