HK Series 303/316 Stainless Steel Quick Couplings | High-Pressure Hydraulic & Industrial Fluid Transfer Solutions
Product Description
HK Series 303/316 Stainless Steel Quick Couplings deliver robust, corrosion-resistant performance for hydraulic, pneumatic, and industrial fluid transfer systems. Engineered for demanding industries like oil/gas, chemical processing, marine, and heavy machinery, these couplings ensure leak-free operation with precision ball-latch mechanisms and self-sealing poppet valves. Choose valved or non-valved designs with threaded or flat-face ports to suit high-pressure (up to 10,000 PSI) and high-temperature environments. The 303/316 stainless steel construction withstands harsh chemicals, extreme conditions, and frequent use, minimizing downtime during retrofits. Ideal for applications requiring instant shutoff, safety compliance, and low maintenance. Industrial-interchange compatibility ensures easy integration into existing systems. Trust HK Series for reliable, durable connections in critical operations.
Standard Materials

• Brass, zinc-plated steel, stainless steel
• Seals: NBR, Viton, EPDM
