Stainless Steel Hydraulic Quick Couplings – KZF Series
The KZF SS304 Hydraulic Quick Couplings from the POOLKE KZF Series are designed for hydraulic, industrial and fluid transfer applications requiring excellent corrosion resistance, reliable sealing and long service life. Manufactured with SUS304 or SUS316 stainless steel materials, this series provides outstanding durability in harsh environments where standard steel couplings may not be suitable.
The KZF Series features a durable ball-locking mechanism, double O-ring sealing structure and captive valve seal design to ensure stable connection performance and minimize leakage. With precision-machined stainless steel components, the KZF SS304 Hydraulic Quick Couplings provide a reliable connection solution for chemical equipment, food processing machinery, laboratory systems and other applications requiring clean and corrosion-resistant hydraulic connections.
Key Features
Stainless Steel Construction
Manufactured from SUS304 or SUS316 stainless steel, providing excellent corrosion resistance and reliable performance in demanding environments.
Durable Ball Locking Mechanism
The precision ball-locking structure ensures secure connection between coupling and nipple and maintains reliable operation during repeated connection cycles.
Double O-Ring Sealing Design
The double O-ring structure provides redundant sealing performance, making it suitable for low-pressure and vacuum applications requiring enhanced leakage prevention.
Reliable Poppet Valve Sealing
The captive valve seal is securely retained by the metal poppet, helping minimize seal washout and damage caused by high-velocity fluid.
Precision Machined Components
The coupling and nipple are precision machined from solid bar stock to ensure accurate dimensions, consistent quality and long service life.
Flexible Material Options
Available in SUS304 and SUS316 stainless steel versions to meet different requirements for corrosion resistance and working environments.
