Omron Replacement Cuff HEM-RML31 for BP710N and BP742N 9-17 Inch

Omron Replacement Blood Pressure Cuff – HEM-RML31 | Fits BP710N & BP742N | Adult Arm 9”–17” (22–42cm) | Omron 3 & 5 Series Advanced Accuracy

Keep your Omron monitor performing at its best. The Omron HEM-RML31 is the genuine OEM replacement cuff designed specifically for the BP710N and BP742N Advanced Accuracy blood pressure monitors. Over time, blood pressure cuffs can lose elasticity, develop cracks, or simply 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 (22–42cm) and connects directly to your existing monitor without any adapters or modifications.

⚠️ Compatibility Notice: This cuff fits ONLY the Omron BP710N and BP742N models (with the “N” suffix). If your monitor is marked BP710 or BP742 without the N suffix, you will need replacement cuff #HCR24 instead. Please verify your model number before ordering.

Frequently Asked Questions

How do I know if this cuff fits my Omron monitor?

Check the model number printed on the bottom or back of your Omron monitor. This cuff (HEM-RML31) is compatible with BP710N and BP742N only — the “N” at the end is critical. If your monitor says 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. Third-party or mismatched cuffs can affect pressure readings. 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?

Omron recommends inspecting your cuff regularly for signs of wear: cracks in the bladder, fraying fabric, or a cuff that no longer holds its shape. Most cuffs last 2–3 years with daily use. If your readings have become inconsistent, a worn cuff is often the cause.

Is the monitor included?

No — this listing is for the replacement cuff only. The Omron BP710N and BP742N monitors are sold separately.
