$3.99
Genuine OEM Plastic Bulkhead Fitting 1-1/2” MPT x 1-1/2” HB (part# PX25) for the Tornado Marathon SE 900 (Model 98170) and Powr-Flite Prowler PFX900S. A MPT-to-hose-barb bulkhead fitting that passes plumbing through a tank wall while sealing the pass-through against leaks.
The Plastic Bulkhead Fitting 1-1/2” MPT x 1-1/2” HB (part# PX25) is a genuine OEM replacement part from the recovery and solution tank assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the bulkhead fitting that passes the 1-1/2 inch line through the tank wall.
What the Plastic Bulkhead Fitting 1-1/2” MPT x 1-1/2” HB does
This bulkhead fitting takes the vacuum line through the tank shell, converting a male pipe thread on one side to a hose barb on the other and sealing against the wall as it passes. It is the only sealed penetration of its size in the tank, so it carries both the vacuum load and the weight of the hose hanging off it.
When to replace the Plastic Bulkhead Fitting 1-1/2” MPT x 1-1/2” HB (PX25)
Replace it when the barb is cracked, the thread is damaged, or the fitting weeps at the tank wall. If you can rock the fitting in its hole by hand, the seal has already failed and the tank will leak under vacuum even if it looks dry when standing.
Plastic Bulkhead Fitting PX25 — fitment and installation notes
Support the fitting inside the tank while tightening from outside so it cannot twist and chew its own seal seat. Do not over-torque — the tank wall is plastic and will distort long before the fitting does. The Tornado Marathon SE 900 and the Powr-Flite Prowler PFX900S are the same machine platform sold under two brand names, so this component carries across both rather than belonging to either one. It is a shared component across the Tornado and Powr-Flite lines and may fit additional models beyond those listed — call us and we will confirm against your serial number.
