What to know before buying

Listing details to confirm

Pressure claims conflict: the title says 100PSI, feature text lists 100psi working and 300psi burst, while the details field says 400 psi maximum. Confirm the applicable pressure ratings before use. The listed nominal wall thickness is "1.3 month," an inconsistent unit that does not establish a usable thickness measurement.

Who is it for?

A good fit for

Buyers seeking a 3/4-inch, 5-foot hose for a compatible coolant or engine-cooling application.
DIY users who can verify hose dimensions, pressure requirements and routing clearance against their system.

Less suited to

Buyers who need an unambiguous pressure rating or verified wall-thickness measurement without checking the listing details.
