Does the job. Easy to assemble and far less expensive than a custom hose

EATON AEROQUIP HOSE 306-4
all good
Works great. Never had the outside covered with oil. If you do you have a leak somewhere it’s not the hose.
Very happy with the quality. I ordered 2 and received 28 Im giving four stars because the delivery took a bit longer than expected.
Does what it is supposed to do, but the outside surface becomes moist with oil soon after initial use. No dripping, but I wish it would stay dry.

Per the supplier: The Shelf life is 32 quarters or 8 years.
The 471 fittings are used on 306 Aeroquip hose. The dash number indicates what size fitting works with the size hose, example 471-4D works with 306-4 hose.
The 306 listed on this page is priced and sold by the foot. We do not sell in fractions of a foot, so for 10 meters your would need to order qty 33 feet and then trim off the 0.2 extra hose.
The 306 hose also has the operating temperatures of -65F to +165F.
No 306 is not approved for fuel. You would want 303 hose.
Yes it can.
