Medical Equipment

Kesaria Rubber Industries manufactures precision rubber, silicone, and PTFE sealing components for the medical equipment industry. Silicone O-Rings, rated across a −60°C to +230°C temperature range, provide reliable high-temperature sealing for steam and sterilization environments. Rubber Diaphragms ensure precise control and sealing inside medical instrumentation, while medical-grade Custom-Moulded Rubber Parts are engineered for fluid-handling systems such as IV infusion pumps, catheters, and surgical instruments. PTFE Washers and Moulded Parts deliver chemically inert, non-reactive sealing for diagnostic and fluid-transfer devices. With 35+ years of precision moulding expertise, Kesaria is a trusted sealing partner for medical device manufacturers across India and export markets.
Silicone & Rubber Seals for IV Infusion Pumps, Catheters & Surgical Instruments

Fluid Handling & Diagnostic Devices

Medical fluid-handling systems – including IV infusion pumps, catheters, and surgical instruments – depend on sealing components that are chemically stable, precisely dimensioned, and manufactured from medical-grade materials for patient safety. Kesaria supplies Custom-Moulded Rubber Parts, Silicone O-Rings, and PTFE Washers engineered for these fluid-transfer and diagnostic applications, where dimensional consistency and material compatibility directly affect device performance and reliability. Every component is produced under strict batch quality controls to meet the exacting tolerances required by medical device OEMs.

Key Points :

  • Custom-Moulded Rubber Parts are manufactured from medical-grade materials for compatibility and safety in fluid-handling systems such as IV infusion pumps,
  • Silicone O-Rings provide inertness and stable sealing performance for diagnostic and fluid-transfer components in contact with medical fluids
  • PTFE Washers and Moulded Parts offer chemically inert, non-reactive sealing - ideal for diagnostic devices requiring resistance to a wide range of chemicals and fluids
  • Precision moulding ensures consistent dimensional accuracy across production batches, reducing rejection rates for medical device OEMs
  • Custom tooling is available for OEM medical device manufacturers requiring non-standard groove dimensions or compression specifications
Rubber Diaphragms for Medical Devices

Medical Instrumentation & Precision Control

Rubber Diaphragms are flexible sealing membranes used inside medical instrumentation to ensure precise control and sealing, preventing the transfer of fluids or gases between chambers while allowing pressure to be accurately transmitted. Kesaria manufactures diaphragms in NBR, Silicone, EPDM, and Neoprene for use in pressure-sensitive medical instruments, flow-control mechanisms, and breathing apparatus – applications where accuracy and material stability are critical to device function and patient safety.

Key Points :

  • Rubber Diaphragms are used in medical devices to ensure precise control and sealing across pressure-sensitive instrumentation
  • Available in NBR, Silicone, EPDM, and Neoprene to match specific chemical, temperature, and flexibility requirements of medical instruments
  • Diaphragms are also used in breathing apparatus, helping maintain safe and consistent air flow
  • Flexible membrane design allows pressure effects to transmit accurately while fully containing the sealed medium
  • Custom diaphragm sizes and profiles are available for OEM medical instrumentation manufacturers
Silicone O-Rings for Steam Sterilization & Autoclave Environments

Sterilization & High-Temperature Equipment

Medical equipment that undergoes repeated steam sterilization cycles requires sealing components capable of withstanding extreme, repeated thermal exposure without degrading. Kesaria’s Silicone O-Rings operate across a −60°C to +230°C temperature range, making them suitable for high-temperature sealing in medical equipment, sterilization processes, and steam environments – conditions under which standard elastomers would lose elasticity or fail. This makes Silicone the material of choice for sealing components inside autoclaves, sterilizers, and other high-temperature medical processing equipment.

Key Points :

  • Silicone O-Rings are rated for a −60°C to +230°C operating range, suitable for steam sterilization and high-temperature medical equipment applications
  • Silicone maintains elasticity and sealing integrity where standard rubber compounds degrade under repeated thermal cycling
  • Suitable for use in sterilization equipment, steam-processing systems, and other high-heat medical device applications
  • Custom Silicone O-Ring sizes are available from 3mm to 500mm inner diameter for OEM sterilization equipment manufacturers
  • Manufactured with flashless precision moulding for consistent dimensional accuracy across production batches
