At Nuvair, we custom fabricate breathing air hose and hose ends. We cut the length of our 7000 psi (345 bar) 1/4" Thermoplastic breathing air refill hose to your specification and install hose ends that you select. The cost of installing hose ends is included in the purchase price. The 527BA-4 hose is commonly used in breathing air applications for different tank fill applications.
527BA breathing air refill hose complies with NFPA 1901 requirements for Fire Apparatus and CGA G7.1-1 Grade E Breathing Air Standards and is suitable for different tank fill applications, such as integrated containment fill stations, mobile and stationary systems (with or without cascade controls), mobile trailer/truck systems, and portable SCBA fill. The 527BA hose does not contain conductive elements; therefore, it should not be used with explosive gases such as pure oxygen and hydrogen. To order hose without hose ends, see SKU 527BA Series (Breathing Air Refill Hose 1/4" & 3/16" · 7000 psi). To order 527BA-4 prefabricated hose and hose ends, see SKU 527BA-4-Series (1/4" 7000 psi Breathing Air Refill Hose & Optional Fittings).
