COMPATIBILITY
System Compatibility
The Autotrol 1001604 adapter is engineered specifically for Autotrol water softener control valves and related systems. The 3/4-inch BSPT threading standard is common in residential water treatment installations and provides a tapered thread seal that creates a watertight connection when properly installed. Verify your existing valve threading before ordering, as BSPT differs from NPT (National Pipe Taper) threading and the two are not interchangeable.
🔧 Pro tip: BSPT threads seal differently than NPT threads. Use a quality thread sealant rather than relying solely on tape, and avoid over-tightening which can crack the plastic threads or distort the taper seal.
