This part cross-references / interchanges with the following part numbers:
What does this power steering pressure line hose assembly do?

What are the pressure ratings?
Sunsong rates this pressure hose at a max working pressure of 1,500 psi, a burst pressure of 8,700 psi, and a tensile strength of 1,600 lb.
Which vehicles does part 3402390 fit?
It fits applications including the Chevrolet TrailBlazer and EXT, GMC Envoy, Envoy XL and XUV, Oldsmobile Bravada, Isuzu Ascender, Buick Rainier, and Saab 9-7X. See the Buyer's Guide tab.
Is the assembly tested before shipping?
Yes. Every pressure hose is subjected to a high-pressure quality assurance test before leaving the factory to help ensure trouble-free installation and operation.
