About This Item
The Pentair U30-74SSZ is the OEM replacement 3/8"-16 x 1" hex head screw for Pentair inground pump housings and select multiport valve assemblies, including the Max-E-Pro, IntelliPro, Dyna-Pro, and EQ Series commercial pump lines.
⚠️ IMPORTANT: QUANTITY REQUIRED VARIES BY MODEL
The Max-E-Pro DOE Series (model 348185) and EQ Series commercial pumps (EQ300, EQ500, EQ750 3PH) each require 4 screws per unit for a complete service. Other models listed require 1 screw. Confirm the quantity needed for your specific model before ordering.
⚠️ IMPORTANT: INTELLIPRO VERSION QUALIFIER
This screw is confirmed for the IntelliPro Variable Speed Pump manufactured before 2019. If your IntelliPro was manufactured in 2019 or later, verify the correct part number against your equipment's parts diagram before ordering.
This fastener secures the pump housing assembly on compatible Pentair inground pump models. Replacing a corroded, seized, or stripped housing screw restores proper clamping force and prevents accelerated corrosion of surrounding hardware. When replacing housing screws during a pump service, inspect all screws at the same time — corrosion on one fastener typically indicates the others are at a similar stage.

Pro Tip
When replacing housing screws during a pump service, inspect all screws at the same time — corrosion on one fastener typically indicates the others are at a similar stage. Replacing the full set in a single service call prevents a return visit when an adjacent screw fails shortly after. Count the screws your model requires (see the Fits Into table above) and order accordingly — models such as the Max-E-Pro DOE and EQ Series require 4 screws per pump.
