Bursting Caps and Plates

Our bursting caps and plates are single-layer metallic rupture elements engineered for high leak-tightness, predictable performance, and absolute reliability. Manufactured from nickel, stainless steel, or advanced nickel-based alloys such as Monel, Inconel, and Hastelloy*, these components are trusted worldwide—most notably in CO₂ cartridges used in fire extinguishers and high-pressure gas systems.

Each unit is precision-designed to prevent accidental discharge, to burst instantly when required, and to protect the container from catastrophic overpressure events. With millions of units deployed globally, these caps and plates deliver proven, repeatable safety performance in critical applications.

Core Safety Functions

• Prevents unintentional gas release, ensuring system readiness at all times.
• Opens instantly at the defined pressure threshold for immediate system activation.
• Protects the container from explosion due to extreme overpressure—e.g., heat exposure during a fire.

Sizes & Performance Range

Available in both small and large production runs, our standard diameters include:

• 7 mm
• 8.5 mm
• 10 mm
• 14.5 mm

Performance capabilities:

• Burst pressures: 120–650 bar
• Temperature range: –80°C to +450°C
• Media compatibility: Gas, steam, and liquids

Custom Specification Options

Every bursting cap or plate can be configured to match your exact application requirements, including:

• Material selection
• Burst pressure calibration
• Temperature and medium compatibility
• Dimensional customisation

Full Traceability & Misinstallation Prevention

To ensure safe, error-free operation, each unit is individually marked with:

• Burst pressure
• Year of manufacture
• Batch number

A unique construction design prevents accidental stacking of multiple caps during installation, eliminating a common failure risk and ensuring the disc ruptures precisely at the intended pressure.

Whether you require ultra-high-volume supply for CO₂ cartridges or precision-engineered components for specialised industrial systems, our bursting caps and plates deliver unmatched reliability, repeatability, and safety assurance.
