【DUAL-LAYER STRUCTURE FOR ENHANCED STRENGTH】Adopting a double-layer design of stainless steel braid and stainless steel corrugation, the hose is significantly sturdier than single-layer alternatives. This structure boosts its load-bearing capacity and extends service life, ensuring reliable performance in high-demand scenarios. 【WIDE TEMPERATURE RESISTANCE】The hose maintains stable performance across an ultra-wide temperature range of -50°F to 750°F, operating reliably even in extreme heat conditions to meet industrial-grade application requirements. 【HIGH-PRESSURE WITHSTAND CAPABILITY】It can withstand a high working pressure of 450 PSI, ensuring reliable performance in high-pressure environments and fulfilling industrial application needs. 【LEAK-PROOF WELDED CONNECTION WITH AESTHETICS】Hose and joints are connected via welding, then precision-ground and polished. This ensures strong structural strength, 100% leak-proof sealing, and a smooth, attractive appearance—combining functionality with visual appeal. 【ROTATING FITTINGS FOR EASY INSTALLATION & VIBRATION ABSORPTION】Equipped with 1/2" NPT male fittings that rotate freely, the hose enables easy installation even with pipe misalignment. It also absorbs vibration from air compressors when connecting to filters, regulators, tanks, or piping, effectively extending equipment lifespan.
