21828 - Replacement Regulator Diaphragm 1.66 OD x .070 (Pack of 5)

Precision Replacement Diaphragms for Industrial Gas Regulators

Maintain the integrity and performance of your gas regulation equipment with this pack of high-quality replacement diaphragms. Designed to meet strict dimensional specifications, these diaphragms feature a 1.66-inch outer diameter and a 0.070-inch thickness, making them suitable for specific regulator models requiring these exact measurements. The diaphragm is the heart of any pressure regulator, responsible for sensing downstream pressure and modulating the valve opening to maintain a steady flow. Over time, these components can wear, crack, or lose flexibility, leading to pressure creep, leaks, or inconsistent gas delivery.

This product comes as a pack of 5, providing excellent value for maintenance departments, repair shops, and welding professionals who manage multiple units. Having spares on hand ensures that downtime is minimized when a regulator fails. These diaphragms are manufactured from durable materials capable of withstanding the mechanical stresses of repeated pressurization cycles while maintaining the sensitivity needed for accurate flow control. Whether you are refurbishing older equipment or performing routine maintenance, these diaphragms are an essential component for restoring factory-level performance.

Proper installation of a new diaphragm is critical for safety and efficiency. Ensure that the regulator body is clean and free of debris before seating the new diaphragm. These parts are designed to provide a reliable seal and consistent response to pressure changes, ensuring that your welding, cutting, or heating operations proceed safely and without interruption. By replacing just the worn diaphragm rather than the entire regulator assembly, you achieve significant cost savings while extending the service life of your valuable industrial equipment.
