Good Quality Replacement
I was worried about aftermarket parts but these look almost identical to the originals. Great value for the price.

Great Value Pack
Getting ten pieces is great for spares. I keep a few in my toolkit for future maintenance needs.

Exact Match
Restored the look of my instrument front panel. The matte finish matches the existing hardware nicely.

Perfect Fit for Bench Supply
These knobs replaced the lost ones on my Agilent E3631A perfectly. The fit is snug and the plastic feels durable enough for daily use.

Slightly Tight Fit
They work well but required a bit more force to push on than expected. Once on, they stay secure.

Q: Are these original Agilent parts?
A: No, these are aftermarket compatible accessories designed to match the original specifications.
Q: How many knobs are included in one order?
A: Each package contains exactly 10 pieces of potentiometer caps.
