Key Advantages
Hot-dip galvanized coating (average thickness 85 um) provides rust protection for extended exposure in humid, outdoor, and saline environments.
Lever-action mechanism provides uniform pressure on the internal gasket to maintain seal integrity under pressure fluctuations up to 20 Bar.
Compatible with standard Perrot, Miller, and French-type quick-connect systems for direct replacement in existing hose assemblies.
Tool-free operation allows a single operator to complete fluid line connections quickly during high-frequency assembly tasks.
Application Scenarios
Agricultural Irrigation
Fast setup for mobile pump units, temporary water distribution, and slurry handling lines.
Construction & Dewatering
High-durability connections for site drainage, pump discharge, and temporary utility pipes.
Industrial Fluid Transfer
Safe connection for non-corrosive liquids, factory waste water, and bulk liquid transfer lines.
Manufacturing Capabilities
ISO 9001:2015 Certified Quality Systems: Rigorous statistical process control (SPC) and traceability protocols govern every production stage-from raw material forging to precision machining and hot-dip galvanizing-ensuring zero-defect delivery.
CNC Machining: Automated, multi-axis CNC centers maintain strict micro-level dimensional tolerances on critical components like locking ears and sealing rings, guaranteeing seamless batch interchangeability and leak-proof performance.
Vertical Integration & Lead-Time Control: Fully in-house forging, galvanizing, and assembly lines eliminate third-party dependencies, giving us direct command over production schedules, rapid prototyping, and custom specifications.
Quality Control
Raw Material Traceability: Raw carbon steel batches are supplied with EN 10204 3.1 Material Test Reports (MTR) verifying chemical composition and tensile limits.
Coating & Thread Inspection: Magnetic thickness gauges verify galvanized zinc layer (≥ 85 um), and standard plug gauges are used to check fitting tolerances.
Pressure & Integrity Testing: Production batches undergo hydrostatic sealing tests and periodic pressure limit sampling prior to dispatch.ISO certificates and raw material MTR documentation are available upon request.
Packaging & Shipping
Packed in heavy-duty corrugated master cartons to prevent transit impact and surface scratches.
Secured with stretch wrap and metal strapping onto fumigated wooden pallets or export-grade plywood crates for safe sea and air transport.
Customized labeling, barcode printing, and pallet branding available upon request to meet specific warehouse requirements.
FAQ
Q: What is the Minimum Order Quantity (MOQ) for wholesale orders?
A: Standard MOQ is typically 100 units per size, subject to raw material availability and production scheduling.
Q: Can couplings be customized with OEM branding or part numbers?
A: Yes, custom stamped logos or laser-marked part numbers on the lever arm or body are available upon request.
Q: How are couplings packaged to prevent damage during sea transport?
A: Items are packed in heavy-duty corrugated cartons and secured on fumigated wooden pallets or in export crates.
Q: What alternative end configurations are available besides hose shanks?
A: We offer weld-on ends, BSP/NPT threaded connectors, and flanged adapters compatible with standard Perrot joint profiles.
Q: What degree of angular misalignment can the joint accommodate?
A: The spherical ball-and-socket design permits up to 15 degrees of angular deflection without compromising connection stability.
Q: Are individual replacement parts like seal rings or levers available?
A: Yes, spare sealing gaskets, lever handles, and safety locking pins are supplied separately for bulk order maintenance.
Q: What is the lead time for a full container load (FCL)?
A: Standard lead time ranges between 25 and 35 days following order deposit confirmation and technical sign-off.
Q: Are product samples available for technical evaluation prior to order placement?
A: Physical sample units can be dispatched for dimensional verification and trial fitting upon request.
Q: What payment terms are accepted for bulk orders?
A: Standard terms include T/T (30% deposit, 70% balance against Bill of Lading) and Irrevocable L/C at sight.
Q: What is the warranty policy for defect claims?
A: We offer a 12-month quality warranty covering structural and manufacturing defects under normal operating conditions.
