High-Pressure Drain Hose for Hydrostatic Testing

The Wheeler-Rex 3917 is a 10 ft discharge hose built for hydrostatic test pumps. It carries a 3,000 psi maximum operating pressure through a 1/4 in inside diameter. NPT connection ends are included for direct attachment. Plumbers and contractors use it to pressure-test piping systems safely.

Pressure Containment and Handling

The hose withstands 3,000 psi during normal test cycles without leaking at the NPT fittings. Its HAWA material resists the fluid pressure generated by compatible Wheeler-Rex pumps. No abnormal noise or vibration occurs when the system is pressurised within the rated limit. The 10 ft length keeps the operator clear of the test point.

Job-Site Durability and Compatibility

The hose mates with Wheeler-Rex hydrostatic test pumps and matches Grainger part numbers 44A746, 44A747, 6GDU4, 6GDU5, 6GDU9 and 6GDV5. NPT ends thread onto standard pump outlets and test caps without adapters. The 1/4 in bore suits typical residential and light commercial test ports. It is not suited for applications requiring larger flow volumes or lower-pressure flexibility.

Questions about this item

How do I install the 10 ft high pressure output hose on a Wheeler-Rex hydrostatic test pump and what step is often missed?

Connect the NPT ends to the pump discharge and tool inlet, then tighten with wrenches on both fittings; the step often missed is using two wrenches to prevent twisting the hose during tightening.

What maintenance or replacement will the 1/4 in hose need after repeated hydrostatic testing at 3000 psi?

Inspect the HAWA tube and NPT fittings for cracks, abrasion or leakage before each use; replace the entire hose assembly if any damage is found or after a burst test failure.

What limit appears first when the 3917 hose runs at its 3000 psi maximum for extended periods?

The 3000 psi maximum operating pressure is the primary limit; sustained use at this pressure can accelerate hose fatigue and fitting seal wear, requiring more frequent inspection.
