Why Choose Our China Clamps?
Anti-Corrosive Performance: Premium grade stainless steel ensures long-term use in harsh marine or chemical environments.
Smooth Edges: The band edges are specially treated to prevent hose damage during installation and high-pressure cycles.
High Locking Torque: Precision-engineered screw and housing prevent the band from slipping or stripping.
Versatility: Ideal for silicone, rubber, and PVC hoses.
Applications:
Automotive: Turbocharger hoses, coolant lines, and air intake systems.
Industrial: Agricultural irrigation, chemical processing, and fluid handling.
Marine: Saltwater-resistant sealing for boat engines and bilge pumps.
How to Install:
Select the correct clamp size based on the hose's outer diameter (OD).
Slide the clamp over the hose before connecting it to the fitting.
Position the clamp at least 1/4 inch from the end of the hose.
Tighten the hex screw using a socket wrench or screwdriver until the connection is leak-proof (avoid over-torquing).
FAQ of Our China Clamp
Q1: What is the difference between American type and German type clamps?
A: American clamps use a perforated band (holes through the band), which provides a very strong mechanical grip. German clamps use a non-perforated embossed band to protect soft hoses from extrusion.
Q2: Can I get these clamps in 316 Stainless Steel for marine use?
A: Yes, we offer W5 grade (Full SS316) specifically for high-salinity environments to ensure maximum corrosion resistance.
Q3: Is custom branding (logo) available on the clamp housing?
A: Absolutely. As a professional China clamp factory, we support OEM/ODM services, including logo stamping and custom packaging for bulk orders.
Q4: Do these clamps meet SAE standards?
A: Yes, our American perforated hose clamps are manufactured and tested according to the SAE J1508 standard to ensure torque and material consistency.
