UL-94 V0 Flame Retardant, Fire-Grade Safety: The cover achieves UL-94 V0 flame retardancy, purpose-built for firefighter breathing air hose applications in high-risk environments — stays flexible in cold and stable in heat to protect lives under extreme conditions.
Three-Layer Construction, Pressure & Weather Resistant: Synthetic rubber tube + high-strength polyester fiber reinforcement + ozone-resistant cover give this supplied air respirator hose an 80bar burst pressure and ozone resistance (ASTM D1149, no cracks after 150 hours), ideal for long-term outdoor service.
-40°C to 120°C Wide Temperature Range: The air breathing hose never hardens in freezing conditions nor softens in high heat, covering cold-region construction and hot workshop applications alike.
Full Size Range & Fitting Compatibility: From 1/4" to 2" inner diameter, compatible with PUSH ON, crimped, and quick disconnect fittings in carbon steel, brass, and SS304/316/316L stainless steel with dedicated clamps — this LP respirator hose connects to virtually any adapter for plug-and-play installation.
Custom Length & Packaging: Available in custom cuts (25/50/100 ft) and carton/reel/pallet packaging, supporting bulk procurement for breathing air supply hose projects.
Sandblasting & Painting Operations: Used as a breathing air hose for sandblasting respirator, delivering clean breathing air to blast hoods and paint helmets for safe work in dusty and confined environments.
Firefighting & Rescue: Paired with positive-pressure breathing apparatus and rescue trolleys, this firefighter breathing air hose supplies a stable air source to responders in smoke-filled emergency scenes.
Industrial Long-Tube Respirator Systems: Connected to long-tube respirators and gas mask respirators as an air breathing hose for respirator mask, ideal for prolonged work in chemical, mining, and coating environments with hazardous gases.
Diving & Underwater Operations: Serves as a low pressure air hose for diving respirator, feeding low-pressure air to dive regulators for underwater inspection and salvage work.
Vehicle & Mobile Air Supply: Integrated with vehicle-mounted respirators and mobile supply trolleys, this 3/8 inch breathing air hose offers plug-and-play breathable air for confined-space rescue and vehicle maintenance in mobile scenarios.
Q1: Can this low pressure breathing hose fit my existing quick disconnect fittings or adapters? A: Yes. Our low pressure breathing hose supports PUSH ON, crimped, and quick disconnect fittings connections, with coupling materials in carbon steel, brass, and SS304/316/316L stainless steel plus dedicated clamps. Just tell us your fitting type and inner diameter (1/4" to 2"), and we will pre-assemble at the factory for true plug-and-play use.
Q2: What are the working pressure and temperature range of this breathing air hose? A: The standard working pressure is 300PSI, with 150/200/400/500PSI options; the temperature range is -40°C to 120°C — no hardening in cold, no softening in heat. The cover is UL-94 V0 flame retardant with an 80bar burst pressure, fully meeting the standards for supplied air respirator hose in firefighting, sandblasting, and other demanding applications.
Q3: Can I customize the length and packaging? A: Yes. We offer custom cutting at 25/50/100 feet or any specified length, with carton, reel, or pallet packaging, in black, red, blue, green, yellow, or white. Whether you need breathing air supply hose for bulk engineering projects or small sample orders, we tailor to your requirements.
