DEFENSE & MILITARY
LEAK TESTING

In defense and public safety, Personal Protective Equipment (PPE) plays a critical role in protecting personnel. Personal Protective Equipment such as respiratory masks, helmets, and protective suits must operate reliably in rain, salt spray, dust, mud, vibration, shock, wash-down and extreme temperatures. ATEQ provides industrial leak testing solutions that verify seal integrity, watertightness, airtightness and ingress protection (IP) at end-of-line (EOL)—so every unit shipped performs as intended, not just the prototypes.

BENEFITS

Even the best designs can fail if sealing is inconsistent during assembly. Invisible defects such as pinched gaskets, mis-seated O-rings, porous overmolding, micro-cracks, imperfect bonding, seam defects, valve leakage, or connector sealing faults can compromise performance. ATEQ leak testing solutions are specifically designed to verify the sealing integrity of Personal Protective Equipment (PPE) used in defense, ensuring that PPE meets strict safety standards throughout its lifecycle.

ATEQ leak testing turns sealing into a measurable, controllable manufacturing parameter:

Fast, repeatable pass/fail decisions
Low false reject rate with optimized fixtures and stabilized measurement
Traceability and SPC for audits, contracts, and supplier quality programs
Reduced RMA / field failures / warranty cost and improved mission readiness

TYPICAL APPLICATIONS

ATEQ supports any product where sealing is functional, safety-related, or contractually required:

Tactical Communication & Hearing Protection

Typical products :

Tactical headsets, in-ear comms, PTT modules, rugged accessories

Critical leak paths :

Seams, O-rings, vents/membranes, cable glands

Benefit :

Ensures sealed electronics and housings remain protected throughout lifecycle conditions.

Respiratory Protection & Air-Path Components

Typical products :

Full/half masks, valves, sealed interfaces, powered air modules (as applicable)

Critical leak paths :

Valves, interface seals, manifolds, air-path assemblies

Benefit :

Validates airtight performance and functional integrity of critical subassemblies.

CBRN / Protective Barrier Systems

Typical products :

Protective suits with sealed interfaces, closures, ports (when specified as tight)

Critical leak paths :

Closures, bonded zones, interface ports

Benefit :

Production screening focused on real leak mechanisms driving nonconformance.

Ruggedized Soldier Equipment
