Precision designs and manufactures custom diaphragms and mechnical seals for a variety of markets. A rolling diaphragm can be used in many different applications. Whether used with a carburetor, pressure regulator, flow control valve, or pumping equipment, a rolling diaphragm design offers unique sealing advantages not available through other seals.
PIC's engineers routinely develop custom diaphragms for use in regulated industries such as UL, FDA, NSF, DoD, CSA, and many others. We will work with your company's engineering staff to provide a custom diaphragm that will meet or exceed all of the various regulations that your product will be required to pass.
