A&D LifeSource Replacement Blood Pressure Cuffs
Official OEM replacement cuffs from A&D Medical for LifeSource upper-arm automatic blood pressure monitors. Available in four sizes — Small (UA-279), Medium (UA-280/UA-280A), Large (UA-281/UA-281A), and Extra Large (UA-282/UA-282A) — to help support accurate, comfortable readings for every arm circumference. All cuffs are latex-free, feature durable hook-and-loop closure, conform to arm shape for consistent cuff placement, and carry a 2-year manufacturer warranty. Choosing the correct cuff size matters: a cuff that is too large can produce readings lower than your actual blood pressure, while a cuff that is too small can produce readings higher than your actual blood pressure. Both standard and newer ISO connector versions (models with an “A” suffix) are available. ISO-compliant cuffs ship with both a new ISO connector and a non-ISO connector so they can work with compatible older and newer LifeSource monitors.
Our Take: These are genuine A&D Medical OEM replacement cuffs, not generic third-party alternatives, so fit and connector compatibility are more predictable. The most important step is measuring your upper arm before ordering. Medium (UA-280A) fits the majority of adults. If you use the UA-789AC, an extra large option is available. Current ISO cuffs include both connector types for broader compatibility with older and newer monitors. FSA and HSA eligible.

Frequently Asked Questions
How do I measure my arm to choose the correct cuff size?
Let your arm hang relaxed at your side. Use a flexible tape measure around the midpoint of your upper arm between your shoulder and elbow. Compare your measurement to the size chart above. If your arm falls on a size boundary, choose the larger cuff.
Which cuff size fits most adults?
The Medium cuff, UA-280 or UA-280A, fitting 9.4 to 14.2 inches, fits the majority of adult arms and is the most commonly ordered replacement size.
What is the difference between UA-279, UA-280, UA-280A, UA-281, UA-281A, UA-282, and UA-282A?
The number identifies the size. The “A” suffix identifies the ISO connector version. ISO cuffs include both connector styles in the package for broader compatibility with compatible LifeSource monitors.
What if my monitor uses UA289A, UA290A, UA291A, or UA-420A cuffs?
If your monitor uses UA289A, UA290A, or UA291A, use the Slim Fit Replacement Cuff page. If it uses UA-420A, use the Wide Range cuff page.
Is the XL cuff compatible with all LifeSource monitors?
No. The Extra Large cuff, UA-282A, is designed specifically for the UA-789AC and is not a universal fit for all LifeSource monitors.
Are these cuffs FSA or HSA eligible?
Yes. These replacement blood pressure cuffs are typically FSA and HSA eligible as qualified medical expenses. Keep your receipt for documentation.
What is the warranty?
A&D Medical LifeSource replacement cuffs carry a 2-year manufacturer warranty covering defects in materials and workmanship. Normal wear and tear is not covered.
I cannot find my monitor model in the compatibility table. What should I do?
Check the bottom or back of your monitor for the exact model number. If it does not appear above, email sales@hrmusainc.com or call 1-800-403-8285 and we can help confirm compatibility.
