Thermoplastic Hydraulic Hose?

[charlz]

I popped a hose the other day on my 32 year old Kubota backhoe attachment (actually rubbed through). The dealer said the PN was no longer available from Kubota so I pulled the hose and took it to a local hyd shop. Turns out most of the hoses on my hoe are thermoplastic and not the steel wired stuff. Cost me $35 instead of $50 to have a hose made up. Stuff meets SAE 100R7 and is rated up to 2750 working psi (my hoe relief valve is 1500). Has a much smaller bending radius which is good on these small tractors.

What cons if any are there to this hose? For being on there 32 years a lot of the hoses have jackets coming off etc but otherwise work fine.

Gates anf Aeroquip has the thermoplastic hose.

I think you may have just answered your own question

32 years and they're still working... 'nuff said!

The thermoplastic hose is good stuff. It's used in a lot of different applications. Where it really shines is when it goes over a pulley. That stuff can flex all day and last as long as anything. The hose shop probably made you the same thermoplastic because that's what you brought in. A lot of people tend to think that it's plastic junk but it's actually good stuff. I have a hand operated crimper that I can use on the jobsite to make hoses on the spot. It's a more popular brand, Synflex. You won't be disappointed.

Thanks for the input. I was curious when I couldn't find any mention of it on here since it is apparently cheaper, bends better and meets the psi requirements of these small tractors. I saw the crimper at $299 plus the cost of dies... definitely cheaper than a crimper for 'regular' hydraulic hose.
