Wilden® TPE diaphragms are durable, low cost and operate over a wide temperature range. Injection-molded of premium grade engineering resins, TPE diaphragms have inherent tensile strength without the need for fabric reinforcement. TPE diaphragms are available in Wilden’s integral piston and EZ-Install diaphragm design as well as the traditional AODD diaphragm shape (pie-shape).
