About This Slim Fit Replacement Cuff
|
|
Cuff wear is normal over time — the fabric stretches, the closure loses grip, or the bladder develops slow leaks that produce inconsistent inflation. When this happens, the cuff rather than the monitor is the cause of inconsistent readings, and replacing it is the most straightforward fix. This genuine A&D LifeSource slim fit replacement cuff is designed to restore proper fit and measurement performance to compatible LifeSource monitors.
The slim fit design wraps closely and securely around the upper arm, supporting consistent positioning and even inflation for repeatable readings. Three sizes cover the full range of adult arm circumferences — Small (6.3”–9.4”), Medium (9.0”–14.6”), and Large (12.2”–17.7”). Measure your upper arm at the midpoint between your shoulder and elbow and select the size that falls within your measurement’s range.

Why size matters: A cuff that is too large produces readings lower than your true blood pressure. A cuff that is too small produces readings higher than your true blood pressure. If your arm falls at a size boundary, choose the larger size for the best fit and comfort.

Frequently Asked Questions
|
|
How do I choose the right size?
Measure the circumference of your bare upper arm at the midpoint between your shoulder and elbow. Match your measurement to the size table above. Small fits 6.3”–9.4”, Medium fits 9.0”–14.6”, and Large fits 12.2”–17.7”. If your arm falls at a boundary between sizes, choose the larger size for a more comfortable fit.
How do I confirm my monitor is compatible?
Check the model number on the front or bottom of your A&D LifeSource monitor. If it appears in the compatibility table above — UA-611, UA-651, UA-651BLE, UA-767F, UA-767FAC, or UA-1030T — this slim fit cuff is compatible. You can also confirm by matching the connector style on your current cuff.
When should I replace my cuff?
Replace your cuff if it no longer holds air consistently during inflation, if the fabric is visibly worn, frayed, or stretched so it no longer seats snugly, if inflation feels uneven or uncomfortable, or if readings have become inconsistent despite correct technique. A worn cuff is one of the most common causes of unreliable home blood pressure readings and is typically straightforward to replace.
