We offer expert services for all types of metal diaphragm applications, no matter how complex.

As a stand-alone manufacturer of precision metal diaphragms, we’re proud to offer flexible metal diaphragm production capacity to all our clients. Our state-of-the-art equipment ensures all products are of the highest quality possible.

With many years of industry experience, we offer expert services for all types of metal diaphragm applications, no matter how complex.

Common Metal Diaphragm Applications and Industries

Diaphragm applications usually fall into one of a few common categories:

  • Isolation: Create seals in systems, such as fluid control systems, to isolate different enclosures from one another.
  • Pressure Reporting/Modulation: Transfer pressure effects from the process system to a closed pressure sensor system.
  • System Failure Points: Act as the first point of failure in a system to prevent system overpressure.
  • Seals: Provide system protection from process fluids, and also protect the process fluid from contamination.


The metal diaphragms we create for our clients are used by a wide range of industries:

  • Food processing
  • Pharmaceutical
  • Semiconductor
  • Medical devices
  • Industrial machinery
  • Consumer electronics

Metal Diaphragms from Hudson Technologies

Standard Metal Diaphragms

Standard Metal Diaphragms

Hudson Technologies manufactures two types of standard metal diaphragms, one for use in high-sensitivity low-pressure (HSLP) applications and the other for use in low-sensitivity high-pressure (LSHP) applications.

All corrugated, these metal diaphragms are available in 1-inch, 1.5-inch, 2-inch, 2.5-inch, and 3-inch diameters and also feature a variety of deflection ranges (measured at 1.0 PSI); HSLP models’ deflection ranges from 0.001 to 0.0133, while LSHP models’ deflection ranges from 0.001 to 0.033.

Custom Metal Diaphragms

Custom Metal Diaphragms

For applications that cannot make use of our standard metal diaphragms, Hudson Technologies offers custom manufacturing services for metal diaphragms of various types, including corrugated, flat, and ring.

We can custom produce diaphragms ranging from 0.2 inch to 18 inches in diameter using materials between 0.0005 inch and 0.018 inch thick.

We keep various materials on hand in our in-house inventory, including several grades of stainless steel, Inconel® grades 625 and 718, Haynes 242, Hastelloy®, titanium grades 1 and 2, Monel®, and 17-7 PH, with many others available as project needs require. Our metal-to-rubber and metal-to-metal presses can produce high-precision parts with low tooling and production costs.
