Choose Your Size
Cuff size is measured by upper arm circumference, not by shirt size or body weight. Measure at the midpoint between your shoulder and elbow with your arm hanging relaxed at your side.
A cuff that is too large reads lower than your true blood pressure. A cuff that is too small reads higher. If your measurement falls in an overlap range, most people are more comfortable and get a better seal with the smaller of the two.
How to measure
- Let your arm hang relaxed at your side. Do not flex.
- Find the midpoint between the top of your shoulder and your elbow.
- Wrap a soft tape measure around the bare upper arm at that point, snug but not tight.
- Match the measurement to the size ranges above.

These two monitors accept the Medium and Large cuff only. There is no small SlimFit cuff for the UA-767F series.
The UA-705V and UA-705VL manual inflate monitors and the UA-789AC extra large cuff monitor use a different cuff family (UA-280A, UA-281A, and UA-282A). The SlimFit cuff will not work with those models. Contact us and we will point you to the correct part.
Why Replace the Cuff Instead of the Monitor
Cuffs wear out long before the monitor electronics do. The bladder loses its seal, the fabric frays at the D-ring, or the hose develops a slow leak. When that happens the monitor still works fine — the cuff just cannot hold pressure, which produces error codes, repeated inflation cycles, or readings that drift from one measurement to the next.
A replacement cuff restores the device to normal operation at a fraction of the cost of a new monitor, and you keep your stored reading history on the unit.
Signs your cuff needs replacing
- The monitor inflates, then immediately deflates without giving a reading
- Error codes related to inflation, cuff fit, or air leak
- Visible cracking, stiffening, or splitting in the bladder or hose
- The hook-and-loop closure no longer grips and the cuff slips during inflation
- Readings vary widely between back-to-back measurements on the same arm
What is in the box
One SlimFit cuff in the size you select, with integrated air hose and connector. The cuff connects directly to your existing monitor — no tools and no adapter needed.
Installing your new cuff
- Power the monitor off and unplug the AC adapter if one is connected.
- Pull the old cuff's connector straight out of the air socket on the monitor. It does not twist.
- Push the new cuff's connector firmly into the socket until it seats. A loose connector is the most common cause of an inflation error after replacement.
- Slide your arm through the cuff loop with the hose running down the inside of your arm toward your palm.
- Position the bottom edge of the cuff about one inch above the bend of your elbow and fasten it snugly — you should be able to slip two fingers underneath.
- Sit still with your back supported, feet flat, and arm at heart level. Take your reading.

Frequently Asked Questions
How do I know which size cuff I need?
Measure the circumference of your bare upper arm at the midpoint between your shoulder and elbow, with your arm relaxed at your side. Small covers 6.3″ to 9.4″, Medium covers 9.0″ to 14.6″, and Large covers 12.2″ to 17.7″. Do not guess from clothing size — arm circumference is the only measurement that matters for cuff fit.
What happens if I use the wrong size cuff?
Your readings will be inaccurate. A cuff that is too large produces a reading lower than your true blood pressure. A cuff that is too small produces a reading higher than your true blood pressure. Either error can lead to the wrong conclusion about your health, so size selection is worth getting right.
Will this cuff work with my UA-767F monitor?
The UA-767F and UA-767FAC accept the Medium (UA-290A) and Large (UA-291A) SlimFit cuffs. There is no small SlimFit cuff compatible with the UA-767F series. If you need a smaller fit for that monitor, contact us and we will check current options for you.
Does this fit the UA-705 or UA-789AC?
No. The UA-705V and UA-705VL manual inflate monitors and the UA-789AC extra large cuff monitor use a different cuff family — UA-280A, UA-281A, and UA-282A. The SlimFit cuff is not compatible with those models.
Is this a genuine A&D part?
Yes. This is the genuine A&D Medical SlimFit replacement cuff, carrying the manufacturer's 2-year warranty. Third-party cuffs may physically connect but are not validated with A&D monitors, and an unvalidated cuff can affect measurement accuracy.
My arm measurement falls between two sizes. Which should I order?
The Medium and Large ranges overlap between 12.2″ and 14.6″. In that band most people get a better seal and more comfort from the Medium. If your arm is muscular or conical in shape, or the Medium feels tight at full inflation, the Large is the better choice.
Can I wash the cuff?
Wipe the outer surface with a cloth dampened with mild soap and water. Do not machine wash, submerge, iron, or use bleach or solvent cleaners. Let it air dry fully before storing.
How long should a blood pressure cuff last?
With normal home use and reasonable care, expect roughly two to three years. Daily use, frequent travel, or storing the cuff tightly folded shortens that. Replace it sooner if you see cracking in the bladder, fraying at the D-ring, or the closure stops gripping.
