Meter Star Gas Water Heater Pressure Diaphragm 10-Pack, Multi-Size Linkage Valve Membrane Kit

A worn, damaged, or ruptured pressure diaphragm in a gas water heater water-gas linkage valve can cause water leakage, ignition problems, irregular water pressure, or inconsistent hot water supply. This Meter Star replacement diaphragm kit helps technicians and homeowners match common membrane sizes during repair or maintenance.

The kit includes 10 pressure diaphragms total: 2 pieces each of 45mm, 50mm, 52mm, 54mm, and 73mm outer diameter. The 45mm, 50mm, 52mm, and 54mm membranes use a monaural single-ear design, while the 73mm membrane uses a binaural double-ear design for different valve layouts.

Designed for gas water heater pressure-sensitive valve operation, the diaphragm responds to water flow changes and helps actuate the gas linkage valve. When the original diaphragm is the cause of the issue, replacement can help restore normal water flow response and gas valve operation.

This multi-size assortment is useful for home water heater maintenance, service calls, and repair inventory where the exact diaphragm size may need to be confirmed after disassembly. Always compare the original diaphragm outer diameter and ear configuration before installation.
