Double Bolts and Double Bands Super Hose Clamp have double screws providing it a high clamping force. Stainless steel heavy-duty double bolts hose clamps have a double band making them a very strong heavy-duty clamp. Contains 2 bridges welded onto the clamp band for optimal hose protection. Contains 2 pairs of solid metal rollers which complement the strength of the double band. The Stainless steel heavy-duty double bolt allows for easy fitting on prefixed hoses. The Double Bolts and Double Bands Super Hose Clamp is a specialized type of hose clamp that offers enhanced strength and stability for securing hoses and pipes in demanding applications. It is designed to provide a secure and reliable connection, particularly for larger-diameter hoses or pipes where increased clamping force is required. Advantages of Double Bolts Heavy Duty Hose Clamp:
- The outer edge of the band with smoothing and shaping treatment precludes the damage of the hose.
- Using high-quality material and precise stamping molding prevents thread stripping.
- With precise design, uniform stress, good sealing ability, can be twisted smoothly, and used multiple times.
- Double Bolts: Unlike traditional hose clamps that have a single bolt or screw mechanism, the Double Bolts Super Hose Clamp features two bolts or screws. This double-bolt design allows for greater clamping force and ensures a tighter and more secure connection.
- Double Bands: In addition to the double bolts, this type of hose clamp also has double bands. The bands are typically made of stainless steel or galvanized steel and provide additional strength and stability. The use of double bands helps distribute the clamping force evenly around the hose or pipe, minimizing the risk of leaks or disconnection.
- Adjustable Size Range: The Double Bolts and Double Bands Super Hose Clamp is available in various sizes to accommodate different hose or pipe diameters. The adjustable screw mechanism allows for precise fitting and tightening, ensuring a proper and secure connection.
- High Strength and Durability: The double-bolt and double-band construction of this hose clamp provides exceptional strength and durability. It is designed to withstand high levels of tension and is resistant to corrosion, making it suitable for challenging environments or applications.
- Wide Range of Applications: The Double Bolts and Double Bands Super Hose Clamp is commonly used in industrial, agricultural, and automotive applications where a strong and reliable connection is crucial. It is particularly well-suited for heavy-duty hoses or pipes that are subjected to high pressure, vibrations, or extreme conditions.

Frequently Asked Questions
What is a double bolt double band super hose clamp?
A double bolt double band super hose clamp uses two parallel stainless steel bands and two tightening bolts to distribute clamping force evenly across a wider area. This design is used for large diameter hoses, high-vibration environments, and applications requiring maximum sealing integrity.
What size range does this clamp cover?
Super hose clamps cover from approximately 50 mm to 360 mm (2 inch to 14 inch) diameter range, addressing large hoses and industrial fittings that standard single-band clamps cannot handle.
What material is used?
Available in all stainless steel SS304 or SS316. The double band and bolt construction is fully stainless for corrosion resistance in marine, chemical, and outdoor industrial environments.
What applications use double band super clamps?
Used on large bore industrial hoses, marine engine cooling hoses, HVAC duct connections, mining water hoses, and any application where a standard single-band clamp cannot provide sufficient clamping force or coverage.
Can these clamps be reused?
Yes, double bolt super clamps can be removed and reused provided the bands and hardware are undamaged. Inspect for corrosion and deformation before reuse in critical applications.
What is the minimum order quantity?
Standard MOQ is 500 pieces per size. Mixed sizes within the same material grade can be combined to reach the MOQ.
