Hose Barb 1/4″ H x 1/4″ MPT 7AT003

The Hose Barb 1/4″ H x 1/4″ MPT (part# 7AT003) is a genuine Tacony OEM replacement part from the chassis assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the straight adapter that takes a 1/4 inch hose onto a 1/4 inch male pipe threaded port.

What the Hose Barb 1/4″ H x 1/4″ MPT does

This is the simplest kind of transition in the plumbing, hose size and thread size the same, nothing stepped up or down. That matters more than it sounds, because a barb that matches the hose keeps full bore through the joint and means the hose is stretched only as far as it was designed to stretch. Undersized barbs leak and oversized ones split hose on installation.

When to replace the Hose Barb 1/4″ H x 1/4″ MPT (7AT003)

Replace it when the barb ridges are worn, nicked or grooved where old clamps sat, when the pipe thread is damaged, or when the body is cracked. A hose that keeps creeping off this fitting is usually reporting worn barbs rather than a bad clamp.

Hose Barb H 7AT003 — fitment and installation notes

Push the hose fully past the last barb before clamping, warming a stiff hose rather than forcing it. Seal the pipe thread with tape or paste wound in the direction of the thread, keeping it back from the first thread so nothing enters the 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.
