Defence and CBRN Seals

TRP design and manufacture technical rubber moulded sealing solutions for the defence industry, including seals for CBRN applications.

Sealing solutions for CBRN protective equipment

Chemical, biological, radiological, and nuclear defence (CBRN defence) or nuclear, biological, and chemical protection (NBC protection) is a class of protective measures taken in situations where chemical, biological, radiological, or nuclear hazards may be present. CBRN defence consists of CBRN passive protection, contamination avoidance, and mitigation.

TRP produces defence seals for CBRN suits and respirators for individual protection, as well as sealing and filtration systems for military vehicles providing CBRN reconnaissance and surveillance.

Durable military seals for CBRN breathing apparatus

Military operators and firefighters are deployed into dangerous settings where CBRN protection is often necessary. TRP work with major OEMs to develop CBRN materials suitable for seals and diaphragms in facemask, respirator-demand valves and assemblies. For breathing apparatus, we produce:

  • Rubber to metal bonded diaphragms and poppet valve seats.
  • Flexible diaphragms with micro-high-precision drilled holes for reliable flow control.

Materials for CBRN protective equipment and extreme operating environments

TRP offer a comprehensive portfolio of elastomer materials formulated to provide both CBRN resistance and dynamic sealing performance in extreme environmental and climatic conditions.

Being required to perform from arctic to desert environments, our materials for our defence seals are capable of confidently withstanding the extremes that these present.

Chemical resistance and low permeation rates combined with ultra-low temperature flexibility are the essential elements that we deliver for demand valve diaphragms for breathing apparatus.

Quality Assurance

Consistency and quality are guaranteed with every one of our military seals as a result of the following:

  • TRP’s advanced manufacturing facility, providing all key process stages, enables full traceability from raw materials to finished components.
  • In-house laboratory resource is used to certify critical characteristics of both raw materials and finished goods to ensure total quality and reliability. Demand valve diaphragms are 100% flow rate tested as a final sign-off.

Quality documentation to meet customer specifications is presented with every delivery of our moulded rubber products.
