304 Stainless Steel Vacuum Inner and Outer Sealing Stamping Parts

Product Description:

These precision-stamped sealing components are crafted from high-quality 304 stainless steel, designed for demanding vacuum sealing applications. Featuring an inner-outer dual-sealing structure, they ensure superior leak-proof performance in vacuum systems, industrial equipment, and precision instruments. Ideal for food processing, electronics, chemical engineering, medical devices, and scientific research, they deliver reliable sealing solutions under extreme conditions.

Key Features

1. Premium Material & Craftsmanship

   • 304 Stainless Steel: High corrosion resistance, oxidation resistance, and mechanical strength, suitable for high-temperature, high-humidity, and chemically aggressive environments.

   • Precision Stamping: Manufactured with high-precision molds for consistent dimensions, smooth surfaces, and burr-free edges, minimizing friction and sealing failure risks.

2. Advanced Sealing Performance

   • Dual-Sealing Design: Inner and outer sealing rings (optional materials: FKM, silicone, etc.) combined with rigid stainless steel support, achieving ultra-low leak rates (10⁻⁵~10⁻¹⁰ mbar·l/sec), compatible with high-vacuum (10⁻⁸ Pa) to low-vacuum (1000 Pa) applications.

   • Wide Compatibility: Supports flange, compression fitting, and standard vacuum interfaces (KF, ISO, CF), ensuring seamless integration with existing systems.

3. Versatile Applications

   • Industrial Use: Vacuum packaging machines, drying systems, vacuum furnaces—ensuring oxygen-free sealing for food, pharmaceuticals, and electronics.

   • Scientific & Medical: Lab vacuum chambers, analytical instruments, medical vacuum lines—maintaining sterile and high-precision environments.

4. Customization Options

   • Tailored solutions available for non-standard sizes, shapes (round, D-shaped, tubular), and surface finishes (electropolishing, sandblasting).
