About This Item
The Pentair Hand Nut Assembly (075280) is the OEM replacement bronze hand nut for the C Series High Performance Commercial Pump line. Two of these assemblies are required per pump — this listing is for one individual unit.
⚠️ IMPORTANT: 2 REQUIRED PER PUMP
Two hand nut assemblies are required for a complete installation on C Series pumps. This listing is sold individually — order two to complete the job.
The hand nut assembly secures the pump strainer cover or volute connection on the C Series Commercial Pump, providing a tool-free, hand-tightened seal at the pump housing. Bronze construction delivers the corrosion resistance and mechanical durability required in commercial pool environments. A worn or damaged hand nut can compromise the seal integrity of the pump housing, leading to air ingestion or water leakage at the connection point.

Pro Tip
When servicing the pump housing, inspect both hand nut assemblies together — if one shows corrosion, thread wear, or cracking at the knurled grip, replace both at the same time. Mismatched wear between the two nuts can create uneven clamping force on the housing, which may allow air ingestion under load.
