Dynarex Replacement RPOC-22PC 5L Concentrator Power Cord Kit (Power Cord, Lock Nut & Bushing), Black, 1 EA

The Dynarex Replacement RPOC-22PC Power Cord Kit restores safe, reliable AC power connection to compatible Dynarex 5-liter oxygen concentrators. Power cords age fast in medical environments—bending, pinching behind furniture, and general wear can cause internal breaks or insulation cracks. A fresh cord prevents intermittent power loss, overheating at the plug, and tripping of the rear strain-relief point.

This kit includes the power cord, lock nut, and strain-relief bushing, matching the original factory configuration. That means you don’t have to improvise hardware or reuse worn strain-relief parts—crucial for maintaining cable anchoring and preventing tug-damage at the electrical inlet.

Where it’s used

• replacing damaged, frayed, or unreliable power cords

• refurbishing rental fleet concentrators

• restoring proper strain relief after back case service

• addressing user-reported power interruptions caused by cable flex fatigue

Why replacement matters

• damaged cords risk arcing, overheating, and shutdowns

• loose strain relief allows cord movement and internal connector stress

• medical concentrators cannot risk intermittent power during use

Service notes

• always disconnect internal power before replacement

• install strain-relief bushing firmly to avoid cord pull-through

• avoid overtightening lock nut—cracked back cases are common from over-torque

Compatibility

• Dynarex 5L concentrators (RPOC-series)

• OEM-equivalent length and plug configuration

What’s included

• 1 × replacement power cord

• 1 × lock nut

• 1 × strain-relief bushing

Keeping spare cord kits on hand minimizes downtime and prevents unsafe temporary fixes like taped cables or mismatched aftermarket cords.
