Hose Clamps

Construction & Agriculture

WDHC PIONEER

For nearly 70 years, NORMA Group pioneered the development of hose clamps and perfected the worm drive hose clamps (WDHC). We remain one of the world's foremost innovators, producers and suppliers to the heavy equipment, construction and agriculture industries. Our portfolio of WDHC's include constant-tension hose clamps that offers a wide range of diameters, screw types, housings and materials to satisfy the needs and requirements of your applications.

Breeze Super-Seal HD

Breeze Super-Seal HD

The Super-Seal HD is the latest breakthrough in clamping technology with Belleville springs. Designed mainly for EPDM rubber or silicone hose connections in fluid applications. This is a worm-drive hose clamp with a high dynamic compensation range as well as a high-pressure, double-bead profile designed to prevent leaks and secure hose connections.

Advantages:
1. High performance compensating clamp allows the use of lower cost hose material.
2. Increase blow-off strength.
3. Modular design allows for additional compensation when required.
4. No special tools for installation
5. Provides a high degree of security in critical applications
6. Unique band design acts as its own integral spring.

Breeze Constant Torque® Heavy Duty

Breeze Constant Torque® Heavy Duty

This clamp starts with heavy duty construction but is a breakthrough in clamping technology. A Belleville spring mechanism permits this clamp to automatically increase or decrease its own diameter due to changes in operational or environmental temperatures.

Advantages:
1. Premium hose clamp for heavy equipment, truck and bus and performance industry.
2. Recommended for use on turbo exhaust sleeves, heater hoses, coolant hoses, intake systems.
3. Virtually unlimited product life - won't rust or corrode and is reusable.
4. No special tool needed for installation.

TORRO® Worm Drive Hose Clamp

TORRO® Worm Drive Hose Clamp

A non-perforated worm-drive hose clamp ideally suited to applications with high mechanical loads.

Advantages:
1. Multi-range hose clamp.
2. Clamping ranges to DIN 3017: 8-16 mm up to 140-160 mm.
3. Larger diameter upon request.

S/SP Sealing clamps

S/SP Sealing clamps

S is a sealing clamp and SP is a retaining clamp. Thanks to their robust clamping brackets with metric bolts the clamping force offered by S/SP is very high. The two-part version is recommended for application submitted to extreme pressure and tensile loads.

Advantages:
1. Strong clamping brackets for high clamping force and optimum sealing
2. The Bridge provide optimum hose protection
3. Robust band with rounded edges (from band width 20 mm) prevents injury and damage to the hose

FBS Springband hose clamp

FBS Springband hose clamp

FBS hose clamp are sutiable for use with hose-spigot connections in areas with exttreme temperature changes. Once assembled, FBS provide a continuously readjusting dynamic lightening effect.

Advantages:
1. Single-part hose clamp without screw.
2. Uniform distribution of clamping force.
3. Temperature resistance from -40°C up to 200°C

Breeze Power-Seal®

Breeze Power-Seal®

This general purpose worm-drive hose clamp is used on combustion engines and industrial usages. This high strength four-piece Quandra-Lock construction exceeds SAE requirements delivering both quality and value.

Advantages:
1. Excellent clamp load.
2. Smooth housing underside ensures more even distribution of sealing pressure
3. Exceeds SAE J 1508 Specifications

Breeze Aero-Seal®

Breeze Aero-Seal®

The original perforated stainless steel worm-drive clamp. Heavy duty four-piece Quadra-Lock construction enables far more tightening to be delivered to the band perforations. Main usage heavy equipment, aircraft and heavy duty industrial applications.

Advantages:
1. Original patented worm-drive clamp
2. Features sider 9/16" (14.2 mm) stainless steel.
3. Available in a wide variety of materials and screw types

Breeze Liner

Breeze Liner

An integral extension of the band as an inner liner protects soft-surface hose (silicone and others) from damage caused by extrusion or shearing through the band slots. Liner clamps afford maximum protection to soft hoses while providing a true concentric seal.

Advantages:
1. Alternative to embosses, non-perforated band clamps.
2. Full range of sizes available for all applications.
3. Heavy duty four-piece Quandra-Lock construction

Breeze Constant Torque®

Breeze Constant Torque®

This clamp starts with the Aero-Seal construction but is a breakthrough in clamping technology. A Belleville spring mechanism permits this clamp to automatically increase or decrease its own diameter due to changes in operational or environmental temperatures.

Advantages:
1. Premium hose clamp for heavy equipment, truck and bus and performance industry.
2. Recommended for use on turbo exhaust sleeves, heater hoses, coolant hoses, intake systems.
3. Virtually unlimited product life - won't rust or corrode and is reusable.
4. No special tool needed for installation.

Breeze Hi-Torque

Breeze Hi-Torque

This strong worm-drive hose clamp features all stainless steel construction. Eight screw-threads are engaged in the in the band simultaneously for high torquing drive, sealing pressure and vibration resistance. Also available with a liner.

Advantages:
1. 5/8" (15.8 MM) band
2. Inner liner available
3. Diameter Range: 1" - 9 1/8"

Breeze Super-Seal

Breeze Super-Seal

The Super-Seal is the latest breakthrough in clamping technology. Designed mainly for EPDM rubber or silicone hose connections in fluid applications. This is a worm-drive hose clamp with a high dynamic compensation range as well as a high-pressure, double-bead profile designed to prevent leaks and secure hose connections.

Advantages:
1. High performance compensating clamp allows the use of lower cost hose material.
2. Increase blow-off strength.
3. Modular design allows for additional compensation when required.
4. No special tools for installation
5. Provides a high degree of security in critical applications
6. Unique band design acts as its own integral spring.

ABA Original

ABA Original

The ABA Original clamps feature unique, one-piece housing, rolled-up band edges and a non perforated (embossed) band that protect the hose. For added corrosion resistance, the band in the 12 mm Standard is made up of Aluzinc giving it 3 times the protection offered by conventional galvanized steel.

Advantages:
1. High clamping force and high durability torque
2. Solid band
3. Rolled up band edges
4. Smooth inside
5. House protected from pipe

TORRO® WF
