China V band clamp manufacturer
HWKG is a professional Chinese manufacturer specializing in the research, development, precision production, and global supply of high-performance V-clamps. With over 20 years of manufacturing experience, we offer durable, leak-proof V-clamps widely used in the automotive, marine, industrial, agricultural, and new energy sectors, and conforming to industry standards such as SAE, DIN, and ISO.
Core Components of Our V Band Coupling
V-shaped Retaining Ring
As the core sealing matching part we produce, it is precision machined with standard wedge V-angle to create full-circle compression sealing. We support manufacturing with stainless steel, titanium and aluminum raw materials, and can customize surface treatments to adapt to high temperature, salt spray and corrosive working environments.
Clamp Outer Band
The main load-bearing component rolled and stamped on our automated production equipment. We control the material thickness and elastic deformation range precisely through repeated testing, ensuring the outer band maintains stable clamping force after dozens of repeated disassembly cycles.
T-Bolt & Nut Fastening Assembly
We adopt high-strength alloy raw materials to produce matched locking kits including T-bolts and anti-loose nuts. Thread surfaces are pre-treated with high-temperature resistant anti-seize structure by our production process, avoiding bolt seizure after long-term exposure to extreme heat and preventing loosening under continuous high-frequency vibration.
Floating/Compensation Insert
Self-developed elastic buffer accessory installed between the outer band and V-ring. It absorbs pipeline thermal expansion and mechanical vibration, fills tiny assembly gaps to boost sealing effect, while reducing friction wear between metal contact surfaces and extending the whole coupling service life.

advantages of HWKG'S V band clamp
HWKG V-band clamps deliver uniform sealing, heat resistance and easy quick assembly
Uniform 360°Clamping & Superior Sealing
Our exclusive V-groove wedge structural design distributes clamping force evenly across the full circumference of the flange. There is no local pressure loss during operation; most standard models do not require extra sealing gaskets and maintain zero leakage under rated working pressure after our factory air tightness inspection.
Fast Mount & Dismount, Low Maintenance
Compared with traditional multi-bolt flange connections, our products only need simple torque wrench operation for assembly and disassembly, cutting on-site installation time by over 70%. Our product structure contains few vulnerable spare parts, greatly extending maintenance cycles and lowering daily equipment upkeep expenses for our customers.
Small & Light, Space-Saving
Our V band clamps are far more compact and lighter than conventional flange connectors. It helps our partners save valuable layout space inside engine cabins and equipment shells, supporting their product miniaturization and lightweight upgrading design demands.
High Temp & Vibration Resistant
Our standard stainless steel clamps stably work within -40℃ to 800℃; customized titanium versions support extreme operating temperatures up to 1200℃. With our optimized anti-vibration structural design, clamping performance stays consistent under long-term continuous vibration.
Reusable, Lower Operation Cost
Our finished products will not suffer permanent metal deformation after repeated disassembly. A set of V-clamps can be reused for multiple equipment overhauls, helping customers significantly reduce long-term replacement and repeated procurement costs.
Common materials for V band clamp
V-band clamps can be made from different materials depending on the application, but HWKG primarily manufactures them in stainless steel due to its excellent combination of strength
Stainless steel V band clamp
Stainless V-band clamps are made using premium alloys such as the 300 series, offering excellent corrosion resistance and reliable. They are the standard choice for many automotive and industrial exhaust applications, since they can withstand high temperatures, thermal cycling, and vibration. These clamps also deliver a stable sealing performance over repeated cycles of assembly and disassembly.
Titanium V band clamp
Titanium V-band clamps use high-grade titanium materials (such as CP2) for lightweight yet robust performance. Because titanium has a high strength-to-weight ratio and outstanding corrosion resistance these clamps are favored in racing and performance exhaust systems where weight savings and durability are premium considerations.
Aluminum V band clamp
Aluminum V-band clamps incorporate aluminum alloy components—often paired with stainless clamp bands—for applications where weight reduction or cost savings are important. While aluminum may not match the high-temperature endurance of stainless or titanium, it provides a lightweight alternative for less severe conditions, such as after-market modifications, general pipework, or equipment where frequent service and quick access are required.
V band clamp Applications
HWKG’s V-band clamp can be applied to various scenarios to meet your diverse needs.
Automotive Exhaust and Turbo Systems
We supply matching clamps for passenger cars, commercial vehicles, off-road vehicles exhaust pipelines, turbocharger inlet and outlet joints, EGR cooling systems and new energy vehicle thermal circulation pipelines.
Industrial Piping and High-Temp Ducting
Our products serve factory boiler flues, waste heat recovery pipelines, chemical high-temperature conveying ducts, smelting ventilation pipes and sanitary high-temperature pipelines for food processing plants.
Agricultural Irrigation Equipment
Our moisture and dust resistant V band clamps are applied to farm high-pressure irrigation main pipes, sprinkler joints, pesticide delivery pipelines and agricultural machinery exhaust connections.
Marine and Offshore Applications
We provide salt-spray anti-corrosion treated products for ship diesel engine exhaust pipes, seawater circulation pipelines, offshore platform ventilation ducts and yacht power system connections.
Installation Tips for V band clamp
01 - Check Pipe Alignment
We remind all partners to ensure two paired flanges are coaxial with flat contact surfaces before installation. Excessive offset will lead to uneven compression and medium leakage after tightening.
02 - Coat Anti-Seize Compound on Threads
We suggest applying high-temperature anti-seize lubricant to T-bolt threads and nut contact surfaces, which can effectively prevent thread rusting and locking during long-term high-temperature operation.
03 - Tighten Gradually and Evenly
We recommend tightening the bolts in 2 to 3 progressive torque steps, rather than tightening them all at once, to avoid over-compression on one side and damage to the V-ring and compensation insert.
04 - Prohibit Impact Tools for Tightening
Instant overload force from impact wrenches easily causes outer band deformation, thread sliding or bolt fracture. We advise using calibrated torque wrenches for precise torque control.
05 - Avoid Long-term Direct Heat Exposure
Keep our V-band assemblies away from open fire and ultra-high temperature heat sources. Install heat insulation shields if they are adjacent to high-temperature components to prevent material performance decline.
06 - Complete Final Air Tightness Inspection
After installation, we recommend testing tightness by smearing soapy water on joint surfaces to check air bubbles; customers with high-pressure industrial pipelines can conduct static pressure holding tests to confirm zero leakage.
