Hose Barb 1/4″ Barb x 3/8″ MPT PX85

The Hose Barb 1/4″ Barb x 3/8″ MPT (part# PX85) is a genuine Tacony OEM replacement part from the chassis assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the adapter that connects a 1/4 inch hose to a 3/8 inch male pipe threaded port.

What the Hose Barb 1/4″ Barb x 3/8″ MPT does

This fitting does a size change and a hose transition at the same time. Doing both in one body means a single sealing joint instead of a bushing plus a barb, and on a pressurised line every joint you avoid is a leak you never have to find. The step down to a 1/4 inch hose is deliberate rather than incidental, so it belongs where the machine drawing puts it and not wherever it happens to fit.

When to replace the Hose Barb 1/4″ Barb x 3/8″ MPT (PX85)

Replace it when the barbs are worn smooth or grooved by previous clamps, when the pipe thread is chased out or cross-threaded, or when the body shows a crack at the shoulder. Recurring leaks at this joint after a proper reseal point at the fitting itself.

Hose Barb Barb PX85 — fitment and installation notes

Aim the barb before final tightening so the hose leaves without a twist, and seat the hose fully past the last barb before clamping. Seal the thread in the direction of the thread and keep the tape back from the leading thread, since a 1/4 inch line blocks easily. 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.
