Hose for Oil Cooler - Source & Type

 

What type of oil cooler hose should I get for a Lyc O-360? Spruce has many types (of hose material) but I don't know which to get.
 

3000 psi aeroquip or equivalent with ends installed by hose shop. Use steel fittings at the cooler. The cooler is very soft aluminum and aluminum fittings tend to gall the aluminum and potentially could ruin the cooler.

Kevin, Speedway motors have an array of Aeroquip hoses and fittings at a far less expensive price than ACS

I used Eaton Aeroquip 303 hose and 491 fittings for the oil lines.? I covered with fire sleeve.? You can make the hoses yourself.? You need a mandrel and EAA has a how-to video on the process.
I used Speedway Phoenix fittings for the low-pressure fuel lines.

Thanks all! Looking at Aeroquip 303 hoses and 491 fittings. But what size? 1/2"? 38"? 1/4"?
?
Should I add the metal shroud to the hose OR must I buy hose with shroud manufactured on it?
?

I used 1/2" -? ?491-8D.? The metal shroud is part of the 491 fitting.? Definitely review the EAA? video on hose fabrication.
I bought my oil cooler from Vans aircraft.? It was less expensive than than spruce, or anywhere else I could find, and then I was assured that it would work with their baffles.
