Unique-Bargains 20 x 20mm Gold Tone Piezoelectric Buzzer Gasket

SKU CH-3M8Q-EH7MH

A set of twenty gold-tone copper gaskets, each .8 inches across and weighing 12 grams total, for piezoelectric buzzer replacements

  • 20mm copper piezoelectric buzzer gasket for precise fit
  • Gold-tone finish resists corrosion in HVAC environments
  • Lightweight 12g disc reduces assembly strain
  • Pack of 20 ensures spares for multiple service calls
  • Copper construction delivers reliable acoustic signal transmission

Pack of 20 Piezoelectric Copper Gaskets

This set contains twenty gold-tone piezoelectric buzzer discs intended for thermostat and pressure washer repairs. Each disc measures 20mm in diameter and is made from copper. The total package weighs 12g and arrives new in a bulk pack. They serve as direct replacement gaskets for compatible devices.

Simple Press-Fit Installation

Installation consists of seating the thin copper disc into the existing buzzer housing or gasket groove. No soldering or tools are required beyond opening the device. The main risk is bending the fragile film during handling, which can prevent proper vibration. Ensure the mating surfaces are clean so the disc makes even contact.

Suitable for Hobbyist Repair Jobs

These discs suit technicians and hobbyists servicing thermostats or pressure washers that use a 20mm piezoelectric buzzer element. They are not for applications needing a different diameter, alternative mounting method or integrated wiring. Buyers who need a complete buzzer assembly with leads should look elsewhere.

Questions about this item

How can I verify the 20mm buzzer disc is functioning after installation?

Apply the rated voltage and listen for a clear audible tone; the 20mm copper disc should produce sound immediately when powered correctly.

What is included in the package and what must be sourced separately?

The pack contains 20 gold-tone 20mm piezoelectric copper buzzer discs; mounting hardware, wiring and drive circuitry are not supplied.

Which version should I choose for a standard 20mm mounting hole?

All discs share the same 20mm diameter and copper construction, so any of the 20 pieces will fit a 20mm hole.
