Metal-Rubber Composite Diaphragm | Machined Metal Parts | Automotive Control Seal

Product Description

This composite diaphragm is a high-precision control component engineered for critical automotive and industrial fluid handling systems. It features a rigid stamped steel substrate for structural stability, paired with a high-performance red FKM/Viton rubber diaphragm vulcanized to the metal for a permanent, leak-proof bond. The rubber section includes a circular sealing lip and X-shaped reinforcement to balance flexibility and pressure resistance, ensuring reliable dynamic sealing under fluctuating pressure and temperature conditions (-20°C to 200°C). The metal frame’s precision-machined notches and positioning points enable exact installation alignment, while the FKM rubber resists petroleum-based fluids, hydraulic oils, and chemical corrosion. This dual-material construction delivers exceptional durability and control accuracy, making it ideal for automotive engine valves, hydraulic regulators, and industrial fluid control equipment where precision and longevity are paramount.

TECHNICAL PARAMETERS

Category	Details
Product Name	Metal-Rubber Composite Diaphragmalve
Part Number	281555485C
Material	Stamped metal substrate (steel) + red FKM/Viton rubber (vulcanized bonding)
Color	Silver (metal) + Red (rubber)
Core Functions	Precision fluid control, pressure regulation, dynamic sealing, vibration damping
Design Feature	Stamped metal frame with integrated rubber sealing diaphragm; X-shaped reinforcement & circular sealing lip
Application	Automotive engine control systems, hydraulic valve assemblies, precision fluid regulators, industrial actuators

Advantages

Dual-Material Performance: Stamped metal provides structural rigidity for installation and pressure resistance, while FKM rubber delivers high-temperature chemical resistance and dynamic sealing—combining metal strength with rubber elasticity.
Precision Sealing: Integrated rubber sealing lip and X-shaped reinforcement ensure tight, leak-proof performance even under dynamic pressure changes and vibration.
Permanent Bonding: Vulcanized rubber-to-metal bonding prevents separation under extreme operating conditions, extending service life by 2–3 times vs. mechanical assembly.
Exact Fit: Machined positioning points on the metal frame enable error-free installation, ensuring alignment with valve bodies and control systems.
Harsh Environment Resistance: FKM rubber withstands high temperatures (up to 200°C) and corrosive fluids, adapting to automotive engine bays and industrial hydraulic systems.

Applications:

- Regulates fluid pressure and flow in automotive engine control modules, ensuring optimal fuel delivery and combustion efficiency.
- Acts as a dynamic seal in hydraulic valve assemblies, preventing fluid leakage while enabling smooth valve actuation and pressure adjustment.
- Dampens vibration in precision fluid regulators, reducing wear on metal components and maintaining stable flow rates for industrial processes.
- Seals the interface between valve bodies and actuators in automotive and industrial systems, protecting internal components from fluid contamination and pressure loss.
- Controls the opening/closing of fluid passages in actuators, enabling precise mechanical movement for automotive and industrial machinery.
