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.

Features

1. Poppet valves available to prevent uncoupled leakage . Poppet valves open automatically when coupled within rated working pressure to keep the flow expeditely.
2. Critical parts are hardened for durability.
3. Compatible with PARKER 60 Series, FASTER HNV Series AEROQUIP FD45 Series and HANSEN HK Series.

Standard Materials

• Brass, zinc-plated steel, stainless steel
