A single jacket 100% filament polyester hose intended for interior protection and occupant use applicationsin buildings and plants. Lightweight and compact, RACK HOSE™ is lined with TPU elastomer, and replaces unlined linen hose. RACK HOSE™ has a service test pressure rating of 250 PSIG (1750 kPa) and is approximately half the weight of conventional rubber lined single jacket hose. RACK HOSE™ is normally installed in hose cabinets and can be ordered prefolded RACK HOSE™ complies with NFPA 1961, FM, and UL 219. . Standard lengths: 50' and 100' (15,2 et 30,5 m).
