1.5 Inch (38mm) Factory Direct Exhaust Pipe Clamping Kits

High-Quality 1.5 Exhaust Clamps

1.5-inch clamps are commonly used in high-performance external wastegate dump tubes, small turbo systems, and parking power units with high-frequency vibration. In tight spaces with high temperature and pressure, exhaust clamps require excellent gas-tight sealing performance.

We maintain strict standards for material selection. Unlike some market products made from recycled stainless steel, we use fully certified AISI 304 high-nickel stainless steel. This material can maintain excellent oxidation resistance and structural integrity even under 800°C extreme thermal cycles, effectively preventing intergranular corrosion and band breakage, ensuring fatigue life in high-performance modification environments.

For the 1.5-inch V-Band series, we carefully optimize the V-groove forming accuracy and bolt angles, combined with multi-stage hydraulic stamping, to ensure 360° uniform clamping between the band and flange. This design allows quick tightening even in single-hand operation spaces. For matching flanges, CNC precision machining keeps male-female groove tolerances within ±0.05mm.

Custom Manufacturing and Large Capacity

As a source factory specialized in exhaust connection and fastening components, we can quickly supply standard-size exhaust clamps and meet detailed custom clamp requirements. From raw material intake to shipping inspection, we follow a full ISO9001 in-house control loop. We also hold IATF 16949 automotive quality certification and maintain a complete material traceability system. Every batch of 1.5" clamps comes with an official spectral test report to ensure compliance with international export standards.

Our technical support can provide deep customization. Whether you need thick-wall bands of specific width or AM350 high-elastic alloy for special conditions, our engineering team can respond quickly from CAD drawing to 3D simulation. To meet brand secondary packaging needs, we support laser marking on the band surface and customized neutral or branded protective packaging, enhancing your product’s brand value.

For orders above 1,000 sets, we can offer highly competitive delivery schedules. Each product undergoes rigorous torque fatigue testing and vibration cycle simulation, providing real factory data to support your brand reputation in global markets.

Common FAQ

What if the clamp cannot rotate enough in a very tight installation space?

Our V-Band clamps support 360-degree rotation for flexible positioning. During installation, you can freely adjust the bolt orientation according to available space in the engine bay. For extremely narrow conditions, we offer a narrow band (Narrow Band) customization option, which reduces band width while maintaining sealing strength, ensuring the clamp can fully close without interference.

What are the minimum order quantity and custom lead time for 1.5" clamps?

Standard-size clamps are stocked for small-batch wholesale (Low MOQ), convenient for market testing. For structural changes or special material customization, our R&D team usually completes prototyping within 7–14 working days. For long-term partners, we can establish dedicated safety stock based on your estimated annual purchase volume for immediate shipment.

How do you ensure clamps are not deformed or scratched during transport?

We use standardized packaging to reduce deformation and surface scratches during transport. Each clamp is individually packed in thick bubble bags with high-strength export cartons. For pallet shipments, we add corner protection and wrap the entire pallet with stretch film. Inner packaging can be adjusted according to product type or customer requirements.
