Hedman Tight Tubes

My current Hedman Tight Tubes are failing. Not too sure how old they are and previous owner is thinking 10ish years but not sure. Left one was cracked bad and a weld job temporarily fixed the issue but the leak is back. Right one is starting to go too. Do these hold up for the most past for a good number of years or are they thrash, which should be avoided? Looks like they do have a ceramic coated option, which may be a bit more durable (part 78503). They do not make them in stainless, which is unfortunate. Basically I want to stick with these if they are dependable so it's an easy plug and play scenario.
