About This Item

The Pentair 1/4"-20 Hex Head Nut (071406Z) is the OEM replacement stainless steel fastener for the IntelliFlo and WhisperFlo variable speed pump families, as well as the ThermalFlo HP Titanium heat pump series.

⚠️ IMPORTANT: 2 NUTS REQUIRED PER PUMP
Most IntelliFlo and WhisperFlo pump applications require 2 nuts per unit. This listing is sold as a set of 2 — one set is the correct quantity for a single pump service.

⚠️ IMPORTANT: VERSION / DATE QUALIFIER
For IntelliFlo VS+SVRS pumps, this nut applies to units manufactured after June 2016. For IntelliFlo i1 and i2 pumps, this nut applies to units manufactured after April 2016. Verify your pump's manufacture date before ordering.

This 1/4"-20 stainless steel hex head nut secures internal hardware assemblies within compatible Pentair pump and heat pump equipment. Stainless steel construction resists corrosion in wet pool equipment environments. Replacing a stripped, corroded, or missing fastener with the correct OEM specification nut ensures proper clamping force and prevents hardware loosening under vibration during pump operation.

Pro Tip

When servicing your pump, check both nuts — corrosion or thread damage on one typically indicates the other is equally worn. Replacing the set of 2 together (as this listing is packaged) ensures matched hardware and avoids a return trip. Match the thread specification (1/4"-20) and head type stamped or visible on your existing hardware before ordering to confirm this is the correct fastener for your application.
