I'm looking for recommendations on an effective but reasonably priced hose for this application. What type of hose is impervious to motor oil? I see that some hoses used for this are PTFE (Teflon) lined, and don't know if this is strictly to reduce friction, or if it is an effective barrier to prevent oil intrusion. Also, is it necessary to have nylon or steel sheathing, or not?

The max pressure in the hose is 70 psig, and max oil temp is 250 degrees F. The twin hoses are about 5 feet long each, and are to be 5/8" ID into either AN10 or 5/8" barbed hose ends.

Thank you.

any hydraulic hose will work with motor oil
most napa stores can make a hydraulic hose with a variety of ends
this is what i used to plumb my hydroboost and power steering
ptfe hoses are impervious to most anything even brake fluid and acid but are costly
i used 5/8'' ptfe w/ss braid for my remote reservoir master cylinder on my hydroboost

I should have added that price is a factor here. When I insert "oil cooler hose" in a Summit parts search, I get both braided nylon clad and bare rubber hose choices. When I insert "fuel hose" I get mostly braided stainless clad hose.

Both nylon and steel clad hose are prohibitively high priced IMHO. Either would cost me around 100 bucks, not to mention another 100 to replace my current barbed fittings with AN10 ends. That's 200 bucks just for hose and hose ends!!!!! I can get by with unprotected rubber hose. I should also add that I'd prefer black hose, like the heater hose I'll be replacing.

My main concern at this time is the type of rubber used for oil line as opposed to fuel and especially coolant. Presently, I have plain old 5/8" ID heater hose in place, which terminates in 5/8" barbed connectors with hose clamps. This system works well, except that AFTER 9 MONTHS, THE OIL HAS PERMEATED THE HOSE WHICH IS SWEATING OIL OVER ITS ENTIRE SURFACE. The hose is still rigid and strong, but must be replaced with an impervious material.

Heater hose wont hold up to 70 psi or 250 degrees, get it changed quickly!

check speedway motors black push on hose 250 psi at 200 deg.$46. for 15 foot of an8..also have aeroquip fc300 hose more money at $8.00 per foot and requires their fittings. this hose for high pressure power steering.

$200 will seem cheap when the heater hose ruptures going down the road and seizes your motor
you could keep the hose barbs and (double) clamps and just change to hydraulic hose for about $40 or $50
quit looking at summit and check out the price at the local napa
that is considered low pressure by hydraulic hose standards

Pay the price and solve the problem once.
I had to, went to braided after an oil cooler hose burnt through
because it ended up too close to my headers.
I clocked the oil filter to cooler adapter wrong.
I was so lucky smelling the oil and shutting the motor off in time,
it comes out at a fair rate.

Thanks to all who replied. The oil lines run along the left inner fender and then down and across to the cooler which is mounted IFO the radiator. It is not in danger of heat, abrasion or cuts, so the armor cladding is not necessary, at this time. I ordered this hose:

Summit Racing® Twist-Tite Hose SUM-220790-B - SummitRacing.com

The supply and return hoses will terminate into existing barbed connectors at both ends.

Again, thanks for your assistance.
