Hose Barb 1/2″ Barb x 1/4″ MPT 7AT004

$5.99

Genuine Tacony OEM hose barb fitting, 1/2 inch barb to 1/4 inch male pipe thread (part# 7AT004), used in the Tornado Marathon SE 900 (Model 98170) and Powr-Flite Prowler PFX900S solution plumbing.

The Hose Barb 1/2″ Barb x 1/4″ MPT (part# 7AT004) is a genuine Tacony OEM replacement part from the recovery and solution tank assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the adapter that converts a 1/4 inch male pipe thread port into a 1/2 inch barbed hose connection.

What the Hose Barb 1/2″ Barb x 1/4″ MPT does

Barb fittings hold because the hose is stretched over ridges and then squeezed back down by a clamp, so the seal is made along the whole barbed length rather than at one line. The thread half of the fitting is what lets a flexible hose meet a rigid component, and getting the barb size right is what stops a hose from either splitting on installation or walking off under pressure.

When to replace the Hose Barb 1/2″ Barb x 1/4″ MPT (7AT004)

Replace it when the barbs are nicked or worn smooth, when the pipe thread is damaged, or when the fitting has cracked at the shoulder. A barb that has been reused through several hoses will often show a groove where old clamps sat, and that groove is a leak path.

Hose Barb Barb 7AT004 — fitment and installation notes

Warm a stiff hose before pushing it on rather than forcing it, and seat it fully past the last barb before clamping. Seal the pipe thread with the correct tape or compound applied in the direction of the thread, and keep tape out of the flow path where it can end up in a valve. 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.
