A rubber air hose, also known as a compressed air hose or pneumatic hose, is used to transfer pressurized air from an air compressor to pneumatic equipment such as rock drills and jackhammers. In mining and construction, a high-pressure reinforced air hose is essential for maintaining stable airflow and preventing energy loss.
Expandag's heavy-duty 3/4" (19mm) industrial air hose is commonly used in mining sites, quarry drilling, and heavy construction environments where stable compressed air supply is critical. Built to withstand extreme conditions, this durable braided air line hose guarantees a consistent, leak-proof air supply for your heavy-duty operations.
Multiple Reinforcement Options: Available in both high-strength textile (Cord Braided) and Steel Wire reinforcement layers to meet different blasting pressure requirements.
Extreme Weather Resistant: The outer synthetic rubber cover is highly resistant to abrasion, ozone, and harsh UV rays found in open-pit mines.
High Working Pressure: Rated up to 300 PSI (Cord Braided) and over 1500 PSI (Steel Wire), easily handling the most demanding industrial air compressors.
Anti-Kink Design: Highly flexible construction prevents kinking and twisting, ensuring smooth airflow for any pneumatic tool air hose application.

This mining air hose is the standard lifeline for pneumatic rock drills (YT28 / YT29A), paving breakers, and industrial air compressor systems. Whether you need a durable jackhammer air hose or a reliable line for HSCA expansive mortar borehole drilling, this hose guarantees top performance.
Pro Tip for Safety: To ensure a 100% leak-proof connection at 300 PSI or 1500 PSI, we highly recommend securing this air line hose with our genuine Double Bolt Clamps and Universal Claw Couplings (Chicago Couplings).
Q: Is this air hose suitable for underground mining?
A: Yes. The abrasion-resistant rubber cover is specifically designed to withstand the harsh scraping and dragging typical in underground mining and quarrying sites.
Q: What is the maximum pressure this compressor hose can handle?
A: Our Cord Braided models handle a continuous Working Pressure of 300 PSI (20 Bar), while our Steel Wire reinforced models can handle extreme pressures up to 1523 PSI (10.5 MPA).
Q: Do you supply the hose in bulk for distributors?
A: Absolutely. We supply wholesale rubber air hoses in standard 50m or 100m rolls, and we can customize packaging and branding for OEM orders.
