Can I use the Danco #95 on a trumpet?

No. It is a faucet bonnet packing, 5/16 in thick, and is not sized or intended for instrument keys. Use the STARTIST washers for brass instruments.

Will the STARTIST washers fit my faucet?

No. They are 3 mm thick cotton felts for instrument stems. A faucet needs a packing like the Danco #95.

The Danco packing is thicker and made for a water seal, but both are felt and wear out. Instrument felts compress with use; faucet packings degrade with water and friction.

Is the STARTIST pack worth $14.29?

If you need spares for several keys, yes: about $1.43 per washer. If you need one washer, a single felt from a repair shop may cost less.

Does the Danco #95 fit all faucets?

No. It is labeled universal, but check your stem and bonnet diameters against 0.38 in inner and 0.69 in outer before buying.

Which is better for a beginner instrument repair kit?

The STARTIST set. Ten washers cover common trumpet and cornet stem sizes, and the soft cotton felt is safe on lacquer.
