8M Mine Hose

Polyester Double Jacket Hose

When reliability counts, you can count on 8M. This premium quality neoprene rubber lined, double jacket hose is Mine Safety & Health Administration (MSHA) approved (#2G-15/1) for the extreme demands of underground firefighting. Engineered for performance, a high-quality polyester reinforced outer jacket protects an inner polyester jacket and rubber liners from wear and puncture while also helping to prevent kinking that limits flow. The all-polyester double jacket construction provides maximum cut and abrasion resistance—ideally suited for mining operations. 8M is suitable for use up to 360 psi (2480 kPa) and is available with brass or aluminum couplings.

 

  • Sturdy Design. Polyester double jacket rubber liner with rubber backing is ultra-strong and resists puncture and wear.
  • Excellent Flow. Smooth rubber liner prevents kinking for maximum flow.
  • Rugged. Performs under pressure at temperature range -5° to 150°F (-20° to 65°C).
  • Certified. Approved by MSHA, Approval #2G-15/1.
