Braided Hose 1/4″ 250 PSI 71817A

The Braided Hose 1/4″ 250 PSI (part# 71817A) is a genuine Tacony OEM replacement part from the brush assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the braid-reinforced 1/4 inch pressure hose that carries pressurised solution between components.

What the Braided Hose 1/4″ 250 PSI does

The braid layer inside the wall is what carries the pressure. Without it the hose would swell with every pump stroke and eventually balloon and split, and the 250 PSI figure is the working pressure that braid is there to hold, not a burst number to design against. That is why substituting clear tubing of the same bore is not a repair, it is a delayed failure with hot solution behind it.

When to replace the Braided Hose 1/4″ 250 PSI (71817A)

Replace it when the outer cover is cut, abraded through to the braid, or has gone hard and cracked, and immediately if any section balloons under pressure or weeps at a fitting. Any hose with exposed or corroded braid is finished regardless of how it behaves on the bench.

Braided Hose PSI 71817A — fitment and installation notes

Cut it square with a sharp blade so the braid is not frayed at the end and the fitting can seat properly. Route it with generous bends and clear of heat and moving parts, and depressurise the system before breaking any joint on this line. Tacony builds the Tornado Marathon SE 900 and the Powr-Flite Prowler PFX900S on a single machine platform, so this component carries across both brands rather than belonging to either one. It is a shared Tacony component and may fit additional models beyond those listed — call us and we will confirm against your serial number.
