Hydraulic rig systems hose
High-pressure hydraulic hoses for drilling rigs and heavy mining machinery. SAE-rated constructions handle extreme pressure spikes and continuous flexing.
Best for: diamond drill rigs, rotary blasthole drills, underground jumbos, hydraulic shovels
High-pressure hydraulic hose
Our high-pressure hydraulic hose is engineered for the extreme demands of mining drilling rigs. The spiral wire reinforcement provides exceptional burst strength and impulse life, withstanding the rapid pressure cycles that occur during drilling operations.
The synthetic rubber tube and cover are formulated for high-temperature resistance and compatibility with premium hydraulic oils. Each hose assembly is crimped with matched fittings and 100% impulse-tested to ensure zero-leak performance in the field. Available in custom lengths with pre-attached fittings for direct replacement on any rig.
Challenges solved by correct hydraulic hose selection
Hydraulic hose burst during drilling
A burst hydraulic hose on a drill rig is not just an equipment failure — it is a safety incident. High-pressure oil spray, sudden machine movement, and unplanned downtime cost tens of thousands per hour. Our spiral-wire hydraulic hose is impulse-tested to 1,000,000+ cycles, providing the reliability that mining operations demand.
Fitting leakage under impulse
Standard crimped fittings often develop micro-leaks under the extreme pressure cycles of drilling rigs, leading to oil loss, contamination, and eventual fitting blow-off. Our computer-controlled crimping process with SAE-matched die sets ensures consistent compression across every assembly. Combined with O-ring face seal or flanged connections, our hoses eliminate leakage at the fitting interface.
Hydraulic fluid leaks from fitting fatigue
Drilling rig vibration loosens standard fittings over time, causing slow hydraulic fluid leaks that are difficult to detect until pressure drops. Our swaged fittings with O-ring face seal design maintain leak-free integrity under continuous vibration, and the hose assembly is impulse-tested to 500,000 cycles.
Case study: Diamond mine drill rig, South Africa
How switching to spiral-wire hydraulic hose eliminated all hose failures for 12 months.
Situation: A diamond mine in South Africa was experiencing hydraulic hose bursts every 3–4 weeks on their production drill rigs. The standard two-wire braid hoses were failing at the fitting interface due to the extreme pressure spikes generated during deep drilling. Each failure caused 4–8 hours of downtime and created oil spill cleanup issues.
Solution: Replaced all main hydraulic circuit hoses with our SAE 100 R12 four-spiral-wire hose, crimped with heavy-duty flanged fittings and bend restrictors at all transition points.
Outcome: Zero hydraulic hose failures in 12 months of continuous operation. Downtime for hose replacement eliminated. Oil consumption reduced by 80% due to elimination of fitting micro-leaks. The mine standardized on our spiral-wire hose across their entire drill fleet.
Hydraulic rig systems hose FAQ
SAE 100 R1 is a one-wire braid hydraulic hose rated for medium-pressure applications (up to 2,250 PSI in smaller diameters). SAE 100 R2 is a two-wire braid hose for higher pressures (up to 4,000 PSI) and more demanding impulse cycles. SAE 100 R12 is a four-spiral-wire hose for the highest pressures (up to 6,000 PSI) and extreme impulse requirements. For mining drilling rigs, we typically recommend R12 spiral hose for the main hydraulic circuits and R2 wire-braid for secondary and pilot circuits.
Impulse life refers to the number of pressure cycles a hydraulic hose can withstand before failure. Mining drilling rigs experience extreme pressure spikes — often from zero to full system pressure thousands of times per shift. Our spiral-wire hydraulic hoses are tested to 1,000,000+ impulse cycles at 133% of working pressure, exceeding SAE requirements. This extended impulse life directly translates to fewer hose bursts on the rig and lower operating costs.
Fitting crimping is critical — the majority of hydraulic hose failures occur at the fitting interface, not the hose body. Our factory crimping process uses computer-controlled machines with die sets matched to each hose diameter and fitting type, ensuring consistent compression within SAE tolerances. Every assembly is impulse-tested before shipment. For mining rig applications, we also offer flanged fittings for high-vibration connections, skive vs. non-skive options for different pressure ratings, and bend restrictors at fitting transition points to prevent stress concentration.
