SPEEDAIRE 114X47 Regulator Diaphragm
This replacement diaphragm fits Speedaire air compressors and restores pressure regulation for pneumatic tools. It is designed for technicians maintaining compatible Grainger part numbers 4ZK86 through 4ZK93 and 4ZM18 through 4ZM20. The part installs directly into the intermediate regulator assembly.
Compatibility Limits for Intermediate Regulators
The diaphragm works only with the specific Speedaire regulator models listed in the compatibility data. It will not fit regulators outside the 4ZK and 4ZM series or other brands without verified cross-reference. Using it on an unlisted model can cause pressure control failure or air leaks.
Service Capacity and Wear Indicators
A new diaphragm provides reliable sealing for standard shop air systems running typical duty cycles. It handles normal pressure ranges until material fatigue or contamination degrades the seal. Replacement is needed when pressure becomes unstable or the regulator leaks constantly.
