3/4" NPT Filter Bowl Adapter
3/4" NPT Filter Bowl Adapter
The 3/4-Inch NPT Filter Bowl Adapter provides a secure transition between a compatible Flow filter-head assembly and standard 3/4-inch NPT plumbing. Its threaded connection helps maintain proper alignment and a leak-resistant fluid path through the filtration circuit. Replace the adapter when its threads, flange surfaces, or sealing interface show corrosion, deformation, scoring, or other damage that could cause leakage or restrict filter servicing.

Installation note: Isolate and drain the filtration circuit before removing the adapter. Clean the mating flange and NPT threads, inspect the sealing element, and apply only the approved thread sealant where required. Start the threaded connection by hand and avoid overtightening, which can damage the adapter or adjoining filter components.
