ISO 7241-1 Series B Certified Stainless Steel Quick Couplings | High-Pressure Hydraulic & Customizable Seals
HK Series 303/316 stainless steel quick couplings meet ISO 7241-1 Series B dimensional standards, ensuring global compatibility for hydraulic and industrial systems. Engineered for extreme corrosion resistance and fluid compatibility, these couplings excel in harsh environments (oil/gas, marine, chemical). Self-sealing poppet valves guarantee leak-free performance under high/low pressure, while hardened components extend service life. Standard Buna-N seals offer broad chemical resistance, with customizable options including PTFE, Fluorocarbon, EPDM, and Kalrez for specialized applications. Precisely tested for safety compliance (up to 10,000 PSI), they integrate seamlessly with Parker 60, Faster HNV, and Hansen HK systems. Customizable thread types, valved/non-valved designs, and material certifications ensure tailored solutions for OEMs and bulk procurement.
