Stenner QP500-1 QuickPro Roller Assembly (OEM Pump Head Replacement Part) The Stenner QP500-1 is a genuine QuickPro roller assembly used inside compatible Stenner peristaltic pump heads.

Take a quick photo of the pump head before disassembly so reassembly is easy and correct. Inspect the pump tube during roller replacement—if it’s stiff, cracked, flattened, or sticky, replace the tube too. Clean chemical residue from the pump head area using a damp cloth and mild cleaner (avoid solvents that can damage plastics). After reassembly, run the pump briefly and check for smooth rotation, consistent output, and leaks at fittings.
