Bodok Seals

Bodok Seals / Bodok Washers – Available From UK Stock

M Barnwell Services are the largest independent manufacturer, stockist and distributor of seals including specialist quality Bodok Seals and Bodok Washers. Bodok Seals are specialised washers to ensure an air-tight seal between the cylinder yoker or regulator of any medical device that requires a gas supply and a gas cylinder. They are essential for ensuring that no gas leaks during operation.

These seals are usually made of neoprene or similar flexible materials. This allows them to withstand high pressure and long-term, repeated use. They are a crucial element of maintaining the safety and effectiveness of gas delivery, especially in the the Medical field. Bodok Seals are used in particular in the administration of anaesthetic gas, where safety is of high importance.

Other popular usage include:

  • Medical Applications: Oxygen Cylinders and Regulators: Commonly used in hospitals, emergency services, and home health care environments where pure oxygen from oxygen regulators to cylinders must be delivered safely.
  • Industrial Gas Systems: Welding and Cutting Gases: essential when ensuring that regulators are securely fitted to gas cylinders without leakage, which is especially important when using gases such as argon.
  • Emergency and Firefighting Equipment: Respiratory Devices: Firefighters use oxygen tanks as part of their equipment. These are fitted with air-tight seals to ensure safe delivery of oxygen with no leakage.
  • Scuba Diving: Diving Equipment: Used in oxygen tanks to prevent oxygen loss and maintain a consistent airflow.
  • Gas Leak Prevention: In gas-related systems, such as in laboratories or industries where precise gas flow is crucial, Bodok seals provide a secure and reusable sealing solution for cylinders containing Nitrogen, Helium, Carbon Dioxide, and other gases.

Materials most commonly used for Bodok Seals:

  • Neoprene® – chemically resistant and elastic
  • EPDM – highly resistant to oxidation and non-toxic
  • Viton™ – high temperature stability and low permeability
  • HNBR  – mechanically strong and resistant to aging
  • Nitrile – excellent compatibility with gas, cost-effective and durable.
