Hose Clamps

Emission Control

NORMA Group pioneered the development of hose clamps. We provide optimal sealing solutions for all industries and their individual requirements and remain one of the world's foremost innovators and producers for numerous OEM industries and emission applications. Our portfolio of hose clamps include constant-tension hose clamps that offer a wide range of diameters, screw types, housings and materials to satisfy the needs and requirements of your applications.

TORRO®

TORRO® worm drive hose clamps are specially suitable for applications under high mechanical loads. Since we are continuously working to improve its features this clamp is still setting standards for modern hose clamp design. The distinguishing feature of the TORRO® is the asymmetrical construction which tells you at first sight whether it is a genuine TORRO® or not.
• Multi-range hose clamp
• Material: W1, W2, W3, W4, W5
• Chromium VI free: compliant with ROHS, WEEE and ELV Environmental Directives
• Clamping ranges to DIN 3017: 8–16 mm up to 140–160 mm
• Larger diameters upon request


TORRO® - THE NOTCH

The notch is a clever option for pre-positioning the TORRO® hose clamp on the hose. In this case the oval hole in the clamp band finds its exact counterpart on the hose surface. Thus the TORRO® is safely and accurately kept in place prior to the final assembly.

• Safe pre-assembly on the hose
• Smart weight saving option without weakening the performance of the clamp

TORRO® - THE PREFIX CLAMP

With this accessory the TORRO® can also be pre-positioned on the hose. The two ‘teeth’ of this device keep the TORRO® hose clamp safely in place if it needs to be stocked or transported prior to its final assembly.

• Safe pre-assembly on the hose

TORRO® - THE SPRING INSERT

For this version of the TORRO® the standard hose clamp is equipped with a spring insert on the inside of the clamp band. When tightening the screw the spring is loaded and stores sufficient clamping force to ensure a long-lasting automatic retensioning effect. Thus the radial clamping force achieved will be sufficient even under extremely low temperatures. Therefore, the TORRO® is an optimal solution for applications under extreme temperature changes.

• Automatic re-tensioning effect in the event of hose relaxation
• Increased sealing reliability across a wide temperature range

TORRO® - THE PREFIX SYSTEM

The PreFix System is a concept for integrated clamps and clips on hoses and pipes. The demand for complete systems that include the appropriate sealing function is increasing.

• Safe pre-assembly on the hose

TORRO® - THE RADIAL INSERT

The Radial® Insert clamp consists of a standard riveted clamp with a stainless steel liner. This insert in the radial acts as a spring.

• Radial integrated element located on the inside of the clamp band
• High contact pressure due to the radially corrugated design
• There are also dynamic properties
• Only available in 9 mm bandwidth

GBS

GBS are particularly suited for sealing suction and pressure lines with plastic or steel reinforcements and high shore hardnesses. Their distinguishing feature is the extremely high band tensile force. The assembly of GBS is easily completed by means of either manual, pneumatic or electric standard tools.



GBS WITH QR CLOSURE

On request the GBS is available with QRC (Quick Release Closure). The hinged bolt can be quickly released and enables the fast and easy assembly or disassembly of the clamp.

• Available in all materials W1, W2, W4, W5.

GBS MULTI-PART VERSION

The two-part version of the GBS is an additional clamp type in this range.

HEAVY DUTY T-BOLT HOSE CLAMPS

T-Bolt hose clamps are intended for use where other hose clamps do not work. Typical applications include air intake systems, cold side charge air hose connections and a variety of hose, pipe and ducting joints.
• Available in diameters 1.75" (44.5 mm) and larger, T-Bolt hose clamps can be configured to suit almost any application and operating environment
• Also available: different materials and Quick Connect or Quick Release latch styles
