Oregon OEM line was fine. Pic below. As seen in some 10 year old I installed in dads back in 2004 to 2014. Only reason pulled it out was broken av and torn boot.
Had got alittle stiff and hardened though. Oregon used black lettering.
Tygon 4040 OEM can last pretty long time if you can put up with hardening and possible shirking around holes to cause leak. But not as long as the Oregon one it seemed.
But that EPA Tygon 1100 is trash shown in my pics above post.
You just cant use the generic wording tygon to describe line from them. You have to know the model number of which one. Not all of them ok.
IMO only the older Tygon 4040 decent, not that epa 1100 crap.
