## Description

## Who it’s for

At 54mm in diameter, these black rubber diaphragms are made for water heater water-pressure diaphragm replacement and maintenance. Their single-ear design identifies the style for matching a repair part.

The 10-piece set is useful for repair work that calls for this type and size of water film diaphragm. The product is described as a universal model suitable for most water heaters, making it relevant for common water-heater and gas-valve maintenance tasks.

Need a replacement diaphragm for a linkage valve repair? This set provides multiple pieces in one matching size, so the parts are on hand when that specific component is needed.

## What you’ll notice day to day

The diaphragm is made of rubber, with reliable sealing and anti-aging listed among its material features. In a water heater repair, the diaphragm’s role is to help promote water pressure, its flexible rubber construction suits that component’s function. The black finish and 54mm diameter also make the part’s basic appearance and size easy to identify while sorting replacement components.

For a repair involving a water-pressure diaphragm, the single-ear form and stated diameter help distinguish this part from a different style or size. The package contains 10 linkage-valve water-film diaphragms, which can support maintenance tasks that call for more than one replacement or keep matching spares together for later work.

## What matters most

The key selection points are the 54mm diameter, rubber material, and single-ear type. Match these details to the diaphragm being replaced and the requirements of the water heater or valve repair. The listing describes the part as suitable for most water heaters, but the size and shape remain useful identifiers when choosing a replacement for a particular repair.

These diaphragms are intended for water heater pressure-diaphragm applications and related gas-valve maintenance. That makes them a focused replacement-part choice rather than a general-purpose rubber washer: the stated use, size, and form are all aimed at a specific role in the water-pressure mechanism. The 10-piece quantity is practical for maintenance where several matching pieces are useful, or for keeping replacements available for future service.

## Before you decide

**How many diaphragms are included?** The package contains 10 linkage-valve water-film diaphragms.

**What size and style are they?** Each diaphragm is listed as 54mm in diameter and has a single-ear design.

**What are they used for?** They are intended for water heater water-pressure diaphragm replacement and maintenance, including related gas-valve work. Match the size and style to the part required for the repair.

## Is it worth it?

For maintenance that calls for a 54mm, single-ear rubber diaphragm, this set brings together the stated size, material, and intended water-heater application in a 10-piece pack. It is a practical fit for repair work centered on the water-pressure diaphragm or linkage valve, especially when having multiple matching replacement pieces is useful.
