Our high-performance Air Breathing Hose is purpose-engineered for critical respiratory equipment, delivering safe, uninterrupted air and oxygen supply for high-risk working environments. Built with a robust three-layer structure of smooth inner rubber, high-tensile reinforcement layer, and UL-94 V0 flame retardant outer rubber, this breathing air hose balances exceptional flexibility, durability, and safety. It adapts to an extreme temperature range of -40℃ to 120℃, with rated pressure options from 150 to 500PSI, ensuring stable performance even in the harshest conditions. Designed for enterprise-level industrial safety clients, our hose meets strict global safety standards for respiratory protection, with customizable configurations to fit diverse equipment needs.
Our flame retardant air breathing hose is the ideal choice for fire fighting respirators, emergency rescue breathing systems, and positive pressure air respirators, providing reliable oxygen delivery in fire-prone and high-temperature scenarios.
Widely used by industrial safety equipment manufacturers and occupational safety service providers, this ozone resistant air breathing hose fits long-tube respirators, gas mask systems, and on-site respiratory protection setups for outdoor construction, mining, and chemical plant operations.
Compatible with diving respirators, on-board marine breathing systems, and underwater operation respiratory equipment, our high pressure air breathing hose maintains consistent performance in humid, high-pressure marine environments.
