About Dia•Com Products

DiaCom Diaphragm Products Molded Diaphragms...Ideal Solution to Tough Sealing Problems

Molded Elastomeric Diaphragms are tough, versatile dynamic seals that eliminate virtually all of the limitations associated with other sealing methods like U-cups, O-rings, metal bellows and flat die-cut diaphragms. They can withstand pressures to 6,000 psi (4.137 bar) over a temperature range from -76°F to 626°F (-60°C to 330°C). We currently manufacture diaphragms ranging in size from 0.1969" to 29.1339" (5 mm to 740 mm).

Dia•Com is dedicated to providing diaphragm seals that enhance the performance and appeal of your product at a price point that helps you compete. Our engineering department stands ready to provide product design support that is both timely and comprehensive.
