Omron Replacement Blood Pressure Cuff, HEM-RML31, Adult, 9 to 17 in

The Omron HEM-RML31 is the genuine OEM replacement cuff designed specifically for the Omron BP710N and BP742N Advanced Accuracy blood pressure monitors. Over time, blood pressure cuffs can lose elasticity, develop cracks, or wear out from daily use — replacing the cuff with an authentic Omron part ensures your monitor continues to deliver the clinically validated accuracy you rely on. The soft, comfortable cuff fits adult arm circumferences from 9 to 17 inches (22 to 42 cm) and connects directly to your existing monitor without adapters or modifications. Monitor sold separately.

Note: This cuff fits ONLY the Omron BP710N and BP742N models (with the "N" suffix). If your monitor is the BP710 or BP742 without the N suffix, you will need replacement cuff HCR24 instead. Verify your model number before ordering.

Ideal For

This replacement cuff is well-suited for patients using Omron BP710N or BP742N blood pressure monitors whose original cuff has worn out, cracked, or lost elasticity after extended daily use. It is an excellent choice for home health providers and caregivers who manage blood pressure monitoring for patients and need a genuine OEM replacement to maintain measurement accuracy. Clinics and physician offices that stock Omron Advanced Accuracy monitors will appreciate having authentic replacement cuffs on hand to extend the life of their equipment without replacing the full monitor. It also serves patients who want to keep a spare cuff available for use across multiple locations, such as home and office, without purchasing an additional monitor.

Frequently Asked Questions

How do I know if this cuff fits my Omron monitor?
Check the model number on the bottom or back of your monitor. This cuff is compatible with BP710N and BP742N only — the N suffix is critical. If your monitor is BP710 or BP742 without the N, order replacement cuff HCR24 instead.

Will replacing the cuff affect my monitor's accuracy?
No, as long as you use a genuine Omron OEM replacement cuff designed for your specific model. This HEM-RML31 cuff is engineered to the same specifications as the original, maintaining the Advanced Accuracy performance of your BP710N or BP742N.

How often should I replace my blood pressure cuff?
Inspect your cuff regularly for signs of wear such as cracks in the bladder, fraying fabric, or a cuff that no longer holds its shape. Most cuffs last 2 to 3 years with daily use. Inconsistent readings can be a sign of a worn cuff.

Is the monitor included?
No. This listing is for the replacement cuff only. The Omron BP710N and BP742N monitors are sold separately.
