 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.
