Rock Drill Hose Manufacturer in India - High Pressure Air & Rock Drill Hose
Heavy-duty rock drill hose manufactured by Flexihose India, a leading rock drill hose manufacturer in India. Purpose-built for rugged pneumatic applications with 35 bar (510 PSI) working pressure and 140 bar (2,040 PSI) burst pressure. Features oil-resistant NBR inner tube, brass-coated steel wire braid reinforcement, and abrasion-resistant outer cover. Available in bore sizes from 1/2 inch to 2 inch. Manufactured in Bhiwadi, Rajasthan by Vardhman Hydraulic Hoses Pvt. Ltd. — supplying factory-direct across India and exporting to the GCC.
What Is a Rock Drill Hose?
A rock drill hose is a heavy-duty, high-pressure pneumatic hose specifically designed for rugged applications in mining, quarrying, and construction. Unlike standard air hoses, rock drill hoses must withstand extreme pressure spikes, abrasion from rough surfaces, and exposure to oil mist from compressors while maintaining flexibility and burst strength.
Our rock drill hose is manufactured to meet IS 446 Type 3 standards. The construction features an oil-resistant nitrile rubber (NBR) inner tube that withstands oil mist from oil-lubricated compressors. This is reinforced with a single braid of high-tensile brass-coated steel wire that handles working pressure up to 35 bar and bursts at 140 bar. The outer cover is a rugged blend of natural and synthetic rubber designed to resist abrasion, cuts, and gouges from rocks and machinery.
Flexihose India (a brand by Vardhman Hydraulic Hoses Pvt. Ltd.) manufactures premium rock drill hose at our ISO 9001:2015 and IATF 16949:2016 certified facility in Bhiwadi, Rajasthan. We offer hoses in bore sizes from 1/2 inch to 2 inch, serving critical industries including mining, quarrying, construction, and EPC projects. As a leading rock drill hose manufacturer in India, we supply factory-direct pan-India and export to markets across the GCC.
Rock Drill Hose Construction & Features
Understanding the three-layer construction that makes our rock drill hose durable, flexible, and reliable for heavy-duty pneumatic applications.
Inner Tube — Oil-Resistant NBR
The inner tube is made from premium nitrile rubber (NBR) compound that resists oil mist from oil-lubricated compressors. This specialized compound also withstands heat and hydrocarbons, ensuring long service life in demanding pneumatic applications.
Reinforcement — Brass-Coated Steel Wire Braid
Single braid of high-tensile brass-coated steel wire provides exceptional strength, handling working pressure up to 35 bar and bursting at 140 bar. The brass coating prevents corrosion and ensures strong rubber-to-metal adhesion.
Outer Cover — Abrasion-Resistant Rubber Blend
The outer cover uses a rugged blend of natural and synthetic rubber that resists abrasion, cuts, and gouges from rocks and machinery. This protective layer ensures the rock drill hose withstands harsh job site conditions.
Field Flexibility Design
Our rock drill hose bends tight without pinching airflow, maintaining full pneumatic efficiency even in confined spaces. The robust construction keeps its shape even if kinked or run over by equipment.

People Also Ask — Rock Drill Hose Troubleshooting & Safety
Why does rock drill hose need oil resistance?
Rock drill hoses need oil resistance because they connect to oil-lubricated air compressors common in mining. The NBR inner tube withstands oil mist that would degrade standard rubber compounds, ensuring longer service life.
What is the burst pressure of rock drill hose?
The burst pressure of rock drill hose is 140 bar (2,040 PSI), providing a 4:1 safety factor over the 35 bar working pressure. This ensures safe operation even during pressure spikes common in pneumatic systems.
How long does rock drill hose last?
With proper use and maintenance, rock drill hose typically lasts 2-4 years in mining applications. Factors affecting lifespan include abrasion from rocks, frequency of use, and proper storage when not in use.
What couplings are used with rock drill hose?
Rock drill hoses typically use claw couplings (Chicago couplings) or threaded fittings compatible with pneumatic tools. Ensure couplings are rated for at least 35 bar working pressure and properly secured.
Can rock drill hose be used for water?
While rock drill hose can handle water, it is specifically designed for air applications. For water-only applications, consider dedicated water hoses. The NBR inner tube is optimized for oil-mist resistance rather than water.
What is the difference between rock drill and air hose?
Rock drill hose has higher pressure rating (35 bar vs 10-20 bar), oil-resistant NBR inner tube, and brass-coated steel wire reinforcement. Standard air hoses lack these features and will fail under rock drill pressure and conditions.
