AEROQUIP HOSE FITTING # 491-8D
As usual. Aeroquip does well
Excellent product and quality. Shipped quickly as well
The RIGHT part I needed for assembling the oil-pressure sensor hose, using Aeroquip-303 hose. Thanks, AC-S!
Seems to hold up well. Be sure to use a mandril when inserting the ferrels or else youll score the inner rubber tubing. Will definitely use again.
Good quality as expected Over priced as expected
Fittings were a snap to install on the associated 303 hose. Pleased with my order.
As others have noted, easy to install, especially if you first look at EAA video on how to. The mandrel for the size you want is a little expensive but very necessary. No can do without the correct size mandrel.
Great project part for student projects.
Easy to assemble.
