End-to-End Reliability from Fox Global
In the oil and gas industry, high-pressure fluid transfer is mission-critical. Whether it’s drilling mud circulating through a rig, compressed air powering abrasive blasting, or high-pressure fluids moving through temporary pipework, the performance of hoses and connections directly impacts safety, productivity, and operational uptime.
At Fox Global, we specialise in providing a complete range of industrial high-pressure hose solutions for the oil and gas sector, engineered to perform in some of the harshest environments in the world. Our diverse product range includes rotary drilling hoses, bull hoses, oil delivery hoses, hammer unions, and hose restraint systems, ensuring our customers are fully covered — from drilling and production to maintenance and shutdown operations.
Proudly family-owned and Australian owned and operated, Fox Global combines global-grade products with local expertise, large stock holdings, and fast turnaround to support oil and gas operations across Australia.
The Critical Role of High-Pressure Hoses in Oil & Gas
Oil and gas operations rely on complex systems operating under:
- Extreme pressures
- High temperatures
- Abrasive and corrosive fluids
- Continuous duty cycles
- Remote and demanding environments
In these conditions, failure is not an option. A single hose failure can lead to:
- Serious safety incidents
- Environmental harm
- Equipment damage
- Costly downtime
That’s why selecting the correct high-pressure hose, fittings, and safety restraints is essential — and why Fox Global takes a complete system approach, not just a product-only mindset.

By sourcing all components from one experienced supplier, customers reduce compatibility risks and improve system reliability.
Rotary Drilling Hoses
Purpose and Function
Rotary drilling hoses are among the most critical hoses on a drilling rig. They are designed to convey drilling mud or air from the rig’s standpipe to the top drive or swivel, while accommodating vertical movement and vibration during drilling operations.
Without a properly specified rotary hose, safe and efficient drilling is impossible.
Construction and Design
Rotary drilling hoses are engineered for extreme conditions and are constructed using:
- Inner Tube: Typically NBR (nitrile rubber), offering resistance to oil, drilling mud, and abrasion
- Reinforcement: Multiple layers (often 2 to 8) of high-tensile steel wire spiral reinforcement
- Cover: Abrasion-, weather-, and ozone-resistant synthetic rubber or chloroprene
- Optional Armour: External armour for additional protection in harsh environments
This construction allows rotary hoses to withstand constant flexing, pressure surges, and abrasive fluids.
Pressure Ratings and Performance
Rotary drilling hoses are designed for high-pressure service, commonly including:
- 5,000 psi (345 bar) working pressure
- 7,500 psi (517 bar) working pressure
- Higher pressure ratings available depending on application
They are suitable for:
- Water-based drilling muds
- Oil-based drilling muds
- Cement slurries
- Air drilling operations
Standards and Compliance
High-quality rotary drilling hoses supplied through Fox Global are typically designed to comply with:
- API Spec 7K
- GB 10544-2003
- SY 5469
Compliance with these standards ensures reliability, safety, and suitability for oil, gas, and geothermal drilling operations.
Applications
- Oil and gas drilling rigs
- Geothermal exploration
- Well servicing and workover
- Cementing operations
- Geological exploration
Usage and Maintenance Considerations
Due to the critical nature of rotary hoses, regular inspection is essential. Operators should monitor for:
- Abrasion or cover damage
- Wire fatigue or deformation
- Cuts or exposed reinforcement
- End fitting integrity
Typical operating temperature ranges from -40°C to +100°C, depending on hose construction.
Bull Hoses
What Is a Bull Hose?
Bull hoses are heavy-duty, large-bore industrial hoses designed to transfer high-volume compressed air, water, or slurry. They are widely used in oil & gas, mining, construction, and abrasive blasting operations.
Construction and Features
Bull hoses typically feature:
- Super synthetic oil-resistant inner liner
- Multiple layers of textile or steel wire reinforcement
- Heavy-duty, abrasion-resistant outer cover (often yellow for visibility)
They are built to withstand rough handling, harsh environments, and continuous operation.
Pressure Ratings and Sizes
- Typical working pressure: around 300 psi
- Safety factors commonly 3:1 or 4:1
- Common bore sizes:
- 2” (51 mm) – industry standard
- Available from ¾” up to 4” depending on airflow requirements
Common Applications
- Abrasive blasting (air supply to blast pots)
- Mining and quarry operations
- Oil & gas construction and maintenance
- Powering pneumatic tools
Using a correctly sized bull hose — such as a 2” or 3” hose — can significantly reduce pressure loss and improve efficiency, particularly in large-nozzle blasting applications.
Oil Delivery and Fluid Transfer Hoses
Fox Global also supplies a range of high-pressure oil delivery hoses designed for the transfer of fuels, oils, and hydrocarbons in oil and gas operations.
Features Include:
- Oil-resistant inner tubes
- Reinforced construction for pressure stability
- Abrasion- and weather-resistant covers
- Compatibility with a wide range of fittings
These hoses are used across production facilities, refineries, service operations, and mobile equipment.
Hammer Unions
What Are Hammer Unions?
Hammer unions are heavy-duty, high-pressure pipe connectors designed for rapid assembly and disassembly without specialised tools. They are a staple connection method in oil and gas operations.
Each hammer union consists of:
- A male sub
- A female sub
- A hammer nut that pulls the connection together
The connection is tightened by striking the nut lugs with a hammer, allowing quick, secure installation.
Pressure Ratings and Materials
Hammer unions are manufactured from forged carbon or alloy steel and are available in pressure ratings ranging from:
- 1,000 psi
- Up to 15,000 psi and beyond
They typically use O-rings or lip seals to create leak-tight connections.
Common Hammer Union Types
Hammer unions are identified by figure numbers:
- Fig 100: Low pressure (air/water/oil), up to 1,000 psi
- Fig 200 / 206: General service, up to 2,000 psi
- Fig 602: Mud service, up to 6,000 psi
- Fig 1502: High-pressure fracturing and cementing, up to 15,000 psi
These connections are essential for temporary pipework, drilling, fracturing, cementing, and well testing.
Hose Restraints and Whip Protection
Why Hose Restraints Matter
In high-pressure environments, hose failure can result in violent hose whip, posing a severe risk to personnel and equipment.
Hose restraints are critical safety devices designed to:
- Absorb energy during hose separation
- Restrict hose movement
- Prevent serious injury and damage
Types of Hose Restraints
Fox Global supplies a range of hose restraint solutions, including:
- Steel cable whip checks
- Woven steel mesh sleeves (whipsocks)
- Nylon hose restraints
Applications and Benefits
Hose restraints are essential for:
- Air and pneumatic systems
- High-pressure fluid transfer
- Hydraulic and water blast systems
- Oil & gas operations
They help sites meet safety requirements and reduce risk in high-pressure applications.
