Brass Bulkhead Fitting 3/4″ PX48
$28.99
Genuine Tacony OEM 3/4 inch brass bulkhead fitting (part# PX48) for the Tornado Marathon SE 900 (Model 98170) and Powr-Flite Prowler PFX900S tank. Carries a plumbed connection through the tank wall and seals it on both sides.
The Brass Bulkhead Fitting 3/4″ (part# PX48) 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 threaded brass fitting that passes a plumbing connection through the tank wall and clamps against it.
What the Brass Bulkhead Fitting 3/4″ does
A bulkhead fitting has to do two jobs that pull against each other. It has to make a pressure-tight plumbing joint, and it has to clamp a flexible tank wall without cracking it. Brass is used because it takes repeated assembly without galling the way a plastic thread does, and because it stays serviceable after years of chemical exposure.
When to replace the Brass Bulkhead Fitting 3/4″ (PX48)
Replace it when the threads are damaged or cross-threaded, when the flange face is scored or no longer flat, or when the body has cracked from overtightening. Persistent seepage that survives a new gasket usually means the fitting itself has been distorted.
Brass Bulkhead Fitting PX48 — fitment and installation notes
Support the fitting inside the tank while tightening the outside so the fitting is not twisting against the tank wall. Use the correct fiber gasket rather than a substitute washer, and do not chase a leak with extra torque, because a brass fitting will happily crack the plastic around it before it gives up. 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.
