QD Coupler 1/4”M x 1/4” FPT PX5
$12.99
Genuine OEM quick-disconnect coupler, 1/4 inch male plug with 1/4 inch female pipe thread (part# PX5), for the Tornado Marathon SE 900 (Model 98170) and Powr-Flite Prowler PFX900S. The plug half that mates with the socket.
The QD Coupler 1/4”M x 1/4” FPT (part# PX5) is a genuine OEM replacement part from the chassis assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the male half of the quick-disconnect that inserts into the coupler body to complete a solution connection. It also fits the Tornado 98168 20″ Marathon 1200 carpet extractor (12 Gallon 115V), all series (B, C, D, E, F and P).
What the QD Coupler 1/4”M x 1/4” FPT does
The male plug is the simpler half and the one that takes the abuse. It is what gets dropped on concrete, dragged across a truck bed and connected wet, and its sealing surface is exposed every time it is disconnected. That surface is what the socket seal closes against, so a nicked or scored plug leaks in a perfectly good coupler body, and swapping the body instead is a common and expensive mis-diagnosis.
When to replace the QD Coupler 1/4”M x 1/4” FPT (PX5)
Replace it when the sealing surface is scored, nicked or corroded, when the latching groove is worn so the socket will not hold it, or when the pipe thread is damaged. If a connection weeps, inspect the plug before assuming the socket is at fault.
QD Coupler M PX5 — fitment and installation notes
Cap or keep the plug off the floor when disconnected, because grit picked up here goes straight into the socket seal. Depressurise before disconnecting, seal the pipe thread properly without overtightening the body, and push the plug fully home until the socket latches before restoring pressure. The Tornado Marathon SE 900 and the Powr-Flite Prowler PFX900S are built on a single machine platform, so this component carries across both brands rather than belonging to either one. It is a shared component and may fit additional models beyond those listed — call us and we will confirm against your serial number.
