Multi-layer hose with internal wire mesh. Very nice tough hose! A sharp 32TPI hack saw and vise was effective to cut house. Used the small 3/16 small size (ID) to replace a short fuel overflow line on my fuel injection bleed rail.

Great product, requires some muscle to get the hose ends to start. My advice, buy the mandrels for the hose size you are using. Without the mandrel you will most likely create a flapper valve on the inner wall of the hose and cause oil or fuel starvation. Use lots of oil in the hose and on the fittings during assembly. The 303 hose will most likely outlive the installer, its a solid and reliable product.
good
