I currently use push lock because I hate messing with SS. I recently saw that some companies have a nylon braided hose, just like SS but nylon. How does these compare in durability for a street driven car?
There are quite a few different weaveloc hoses, some are very expensive and most are very light. I use the earls prolite hose with crimped ends and with a typical drysump car i'll save 40#'s of weight.
Any of the leading mfgrs' woven hoses are approved by nhra and the braid is a combination of nomex and kevlar and is very durable. I brought in a piece of the professional products" braid hose and it has an inner braid of stainless wire imbedded into the rubber.
So i guess that the short answer to your question is that it will hold up just fine in a street car, i would just keep it out of direct sunlight as UV light can raise hell with the rubber-like compound inside the weave. btw, the woven hose is much nicer to work with and a great deal more flexible.
Ive been told not to use the nylon hose on vacuum pump, due to possibly collapsing. There is a steel coil like insert, that can be placed inside of the line to prevent it from collapsing. Keep that in mind.
