A practical reference to rubber diaphragm types, elastomer materials and the key design considerations — stroke, pressure, fatigue life and fabric reinforcement. Engineers use it to specify flat, rolling or convoluted diaphragms for pumps, valves, actuators and regulators, and ARC molds each one to your exact spec.

If you are searching for how to design or spec a rubber diaphragm for a pump, valve, actuator, regulator or pressure switch, use it to match the profile and compound to your media, temperature and cycle-life targets before you request a part.
ARC molds each diaphragm to your exact drawing — flat or rolling, with or without fabric reinforcement — in the elastomer your application calls for, from NBR and EPDM to silicone, FKM and food-grade compounds. With 20 years of US custom manufacturing under ISO 9001:2015 and IATF 16949:2016, we confirm the material, tooling and tolerances and turn your dimensions and pressure requirements into a fast quote.
American Rubber Corp designs and manufactures custom rubber diaphragms for pumps, valves, regulators, actuators, and pressure-sensing applications. This guide covers diaphragm types, materials, and the design factors — pressure, stroke, temperature, and media — that determine the right construction for your part.
