When it comes to hose connections, selecting the right clamp is critical for leak-proof performance, safety, and durability. Our customers often ask: “Which clamp should I use?”
Here’s a simple guide to help you select the right type of Clamp for your application:
1. Worm Drive Clamps
Construction: A band with slots that are engaged in screw threads, all assembled in a Housing which holds all things together. As you rotate (tighten) the screw, the screw pulls the strip & the clamp tightens.
Application usages for Worm Drive Clamps:
- Automotive fuel lines
- General plumbing
- Domestic & light industrial applications
- Automotive Air Intake & Filter Applications
Advantages of Worm Drive Clamps:
- Economical and versatile
- Easy to install & remove
- Wide availability of sizes
Limitations of Worm Drive Clamps:
- Not suitable for very high-pressure applications
- Can loosen under vibration if not fitted properly
Best for: Customers looking for low-cost, general-purpose solutions.
2. T-Bolt Clamps
Construction: It consists of a much wider band as compared to worm drive clamps, whose ends are looped to hold the T-housing and T-bolt. The T-bolt clamp is tightened with a Locknut, which, when turned, brings the clamp loops closer and tightens the clamp.
Application usages of T Bolt Clamps:
- Trucks, tractors, and commercial vehicles
- Heavy machinery & construction equipment
- Agricultural sprayers, compressors, exhaust systems
Advantages of T Bolt Clamps
- Provides strong, uniform clamping force
- Withstands vibration & pressure
- Durable for long-term heavy-duty use
Limitations of T Bolt Clamps:
- Slightly higher cost than worm drive
- The application of this clamp is limited to 120°C due to the presence of a Nyloc insert Nut.
Best for: Customers in automotive, agriculture, and heavy machinery where strength & reliability are critical.
3. V-Band Clamps
Construction: A V-band clamp consists of V-shaped petals welded inside a T-bolt clamp. These V-petals sits on the V-profile of the two mating flanges. When the T-bolt Nut is tightened, the band applies uniform 360° clamping force, pulling the flanges together to create a strong, leak-proof joint.
Application usages of V Band Clamps:
- Turbochargers & exhaust systems
- Industrial piping & ducting
- High-temperature, high-pressure systems
Advantages of V Band Clamps
- Provides a strong, leak-proof seal
- Easy assembly & disassembly for maintenance
- Compact & professional appearance
Limitations of V Band Clamps
- Higher cost compared to worm drive & T-bolt
- Requires matching flanges (not for hose-only use)
Best for: Customers in automotive performance, exhausts, and high-pressure industries.
