Zhejiang Zhengna Technology Co., Ltd. is a leading manufacturer of premium stainless steel hose clamps designed for secure, leak-proof connections in demanding environments. Our clamps, featuring the reliable worm drive mechanism, are engineered for maximum durability, corrosion resistance, and ease of installation.
Manufactured from high-grade SUS304 or SUS316 stainless steel through precision stamping and forming processes, they are the ideal solution for automotive, marine, industrial machinery, and HVAC systems where reliability is non-negotiable. As an IATF 16949 certified contract manufacturer, we ensure every clamp meets stringent quality standards and offer complete customization to fit your exact specifications.
Product Features & Advantages
-
Superior Corrosion Resistance: Made from SUS304 (A2) or SUS316 (A4) stainless steel, offering excellent protection against rust and corrosion in wet, salty, or chemically aggressive environments.
-
Robust & Reliable Locking: The worm drive mechanism with a rolled-edge band and precision-stamped housing provides strong, even clamping force and prevents slippage or hose damage.
-
Precision Engineered: Manufactured using high-precision stamping dies, ensuring consistent band thickness, smooth edges, and perfect thread engagement for easy tightening with a screwdriver.
-
Wide Range & Custom Sizes: Available in standard diameters from 8mm to 200mm. We specialize in custom sizes, band widths, thicknesses, and head styles (hex, slotted, security) to meet unique application needs.
-
Durability & Long Service Life: The stainless steel construction withstands vibration, thermal cycling, and UV exposure, ensuring a long-lasting, maintenance-free seal.
