Pressure Dynamics supplies and supports a range of FRAS (Flame-Resistant and Anti-Static) hose assemblies engineered for use in hazardous and high-risk environments where ignition control and electrostatic dissipation are critical. These hoses are commonly deployed in underground mining, tunnelling, oil and gas, and explosive-rated industrial and defence sites.
Flame-resistant, anti-static hose Hoses (FRAS)
All FRAS hoses provided by Pressure Dynamics are fully compliant with AS 2554 and AS 2660, and are selected to align with operational safety requirements under AS/NZS 60079, AS/NZS 1020, and IEC 60079-32, particularly in hydrocarbon and hazardous zone environments. Assemblies are tested, certified, and ready for immediate installation across both fixed infrastructure and mobile plant.
AS 2554 Compliant Hoses
Hoses manufactured to AS 2554 are intended for air and water delivery in environments requiring flame resistance and anti-static performance. These hoses are suitable for a wide range of applications, including surface mining, industrial processing, and fuel vapour transfer where static electricity could pose a hazard. They are reinforced for strength and flexibility and constructed with anti-static and flame-retardant compounds to meet workplace safety requirements.
Pressure Dynamics supplies a full range of AS 2554-compliant hoses, including single- and multi-ply reinforced rubber and PVC-blend variants. These assemblies can be customised with crimped or reusable fittings and are delivered tested and tagged. Each hose is pressure-rated, and supported by complete traceability documentation and certification.
Services include
- Tested for flame resistance per AS 2554
- Anti-static properties for explosive atmospheres
- Suitable for air, water, and general fluid transfer
- FRAS rubber and PVC-rubber blended construct
- Available with crimped or reusable fittings
- Supplied with compliance tags and test documentation
AS 2660 Compliant Hoses
AS 2660 governs the use of FRAS hose in underground coal mining and other confined, explosive-risk environments. The standard mandates testing for flame propagation, electrical resistance, and materials performance under severe conditions. These hoses are designed to provide critical safety assurance in operations where any form of ignition or static build-up could result in serious incident.
Pressure Dynamics supplies AS 2660-compliant hose assemblies used across dust suppression, water discharge, ventilation air, and slurry transfer applications in underground mines and tunnelling projects. Each hose is manufactured using FRAS-rated compounds and undergoes rigorous testing, with pressure and conductivity validation performed in-house prior to dispatch.
Services include
- Fully compliant with AS 2660 (FRAS – underground mining)
- High abrasion and flame resistance
- Electrically conductive to control static charge build-up
- Available in standard and heavy-duty grades
- Supplied with MSHA/MDG approvals where required
- Pressure-tested and tagged for underground deployment
FRAS Hose Applications
Our FRAS hose assemblies are purpose-built for use in environments where flame propagation and static electricity pose significant risks. Designed to meet the needs of Pressure Dynamics’ core sectors, these hoses are used in both fixed infrastructure and mobile operations where compliance, safety, and durability are essential.
Hose applications span a broad range of hazardous settings, from mining and tunnelling to hydrocarbon processing and defence logistics. In oil and gas environments—both onshore and offshore—hose selection is guided by hazardous area classifications and static control requirements under AS/NZS 60079, AS/NZS 1020, AS 2683, and IEC TS 60079-32-1, which collectively justify and often mandate the use of FRAS-rated assemblies.
Services include
- Hazardous zone refuelling and vapour recovery (Energy & Marine)
- Underground mining and tunnelling services (Resources)
- Fuel and air handling on naval vessels and mobile assets (Defence)
- Dust suppression, ventilation, and dewatering (Infrastructure & Resources)
- Pneumatic tool supply and compressed air systems in Zone 1/2 areas (All sectors)
- Temporary installations and commissioning under hazardous zoning (All sectors)
