Hydraulic hose assembly

The Wheeler-Rex 700821 is a coupled hydraulic hose assembly built for systems that need a 3/8 in inside diameter and a 20 ft run. It uses nitrile tube material with a neoprene cover and carbon steel braid reinforcement to handle fluid transfer in industrial and mobile equipment.

Thermals noise and power draw

The hose is rated for a maximum working pressure of 3,000 psi at 70 F and operates across a temperature range of -40 to 250 degrees F. Its SAE 100R17-6 construction resists heat and pressure cycling without external power or moving parts, so it adds no noise or electrical load to the system.

Replaces worn or short hose runs

This assembly replaces damaged, aged or undersized hose lines where 1/2 in NPT fittings on both ends are required. The jump is worth it when the existing hose cannot meet the 3,000 psi rating, the temperature extremes, or the needed 20 ft length in a single coupled piece.

Questions about this item

How do I install the 1/2 in NPT fittings on the 3/8 in ID hose without damaging the nitrile tube?

Thread each carbon-steel fitting by hand until the NPT taper seats, then tighten one half-turn with a wrench; over-torquing crushes the nitrile liner and creates a leak path.

What maintenance does the neoprene cover and carbon-steel braid need over time?

Inspect the black neoprene cover every few months for cracks, abrasion or oil swelling; replace the 20 ft assembly immediately if the braid shows corrosion or the cover is cut.

At what point does the 3,000 psi rating become the limiting factor during sustained use?

The 3,000 psi maximum working pressure at 70 F is the first limit reached; pressure spikes above that value or temperatures near 250 F reduce the safety margin rapidly.
