Rubber Diaphragm Seal

This Rubber Diaphragm Seal is a precision-molded component developed for reliable performance in industrial sealing systems. Designed to maintain consistent elasticity and strength, it is widely used in pumps, valves, and pneumatic actuators. Its optimized geometry ensures stable operation under pressure fluctuations and varying temperatures, making it a durable and cost-effective solution among industrial rubber components.

Manufactured from High Nitrile DTD 560 Grade 'A' Quality 'P' or Carboxylated Nitrile (85°–95°), this diaphragm provides excellent oil and fuel resistance. The selected nitrile compound offers long-term resilience against wear, compression, and chemical exposure. With its smooth molded surface and uniform wall thickness, this nitrile rubber part ensures secure sealing and dimensional stability during continuous mechanical use.

Outer Diameter: 4.75 in

Inner Diameter: 2.99 in

Central Hole: 0.275 in

Thickness: 1.3 in

Edge Design: Eight finely molded corrugations (R0.03) on the inner rim improve flexibility and pressure responsiveness.
