Clamp Bands

The GBS clamp, made of galvanized steel, provides excellent corrosion protection. It works perfectly in hydraulic, pneumatic, and ventilation systems. We offer a wide range of sizes—from 25 mm to over 90 mm in diameter—allowing them to fit various pipe and hose diameters. We recommend the reinforced GBS SUPER clamps for connections exposed to heavy loads, such as in construction machinery. In turn, the miniature “mini” variants are ideal for precision installations in the automotive and electronics industries. Installation and Use of GBS

Clamps Installation begins with thoroughly cleaning the surface of the pipe or hose. Next, place the GBS clamp onto the component to be connected, ensuring that it fits snugly. Tighten the clamping screw evenly using the appropriate torque. Avoid over-tightening, which can damage the clamp or the component being connected.

When selecting the clamp size, use the outer diameter of the pipe or hose as a guide. Allow for 1–2 mm of installation clearance to compensate for dimensional tolerances. The GBS clamping system is distinguished by its ease of installation and removal. It allows for repeated use of the clamps without compromising their performance. Regular inspection of the technical condition and retightening of the screws as needed extends the service life of the connections.

These products are characterized by high resistance to shaking, vibration, and variable loads. Their other advantages include
: - quick and easy installation without specialized tools,
- reusability of the clamps,
- high leak tightness and durability of connections,
- resistance to corrosion and weather conditions,
- versatility for use across various industries.

GBS clamps made of stainless steel perform well in aggressive chemical environments. We offer comprehensive installation solutions tailored to individual needs. Select and order the optimal clamps for your application!

If a hose starts to sweat, slips when heated, or still shows signs of leakage after tightening, the problem is often not the hose itself, but an improperly selected automotive clamp. In this category, it’s easier to select the correct diameter range, clamp type, and strap width for the actual operating conditions under the hood.

Automotive clamps in this group are used to secure hoses and tubing, but they differ in design. Some are better suited for higher loads and stiffer hoses, while others work well with smaller diameters, where precise clamping and gentle contact with the rubber are crucial.

How do you choose an automotive clamp based on the hose’s diameter and type?

Selecting the diameter starts with measuring the outer diameter of the hose already fitted to the fitting. The clamp’s size range should match this measurement with a small margin for adjustment, because a clamp that’s too tight makes installation difficult, while one that’s too loose makes it hard to achieve the proper clamping force.

The GBS W1 clamp is available in many sizes, ranging from 25–27 to 86–91 mm, making it easier to fit thicker connections. The FORCE W1 screw clamp covers a range of 16–25 mm and works well where the diameter is smaller and installation space is limited.

How does the clamp’s design perform in real-world applications?

Automotive clamps are not subjected to stress solely during tightening. During operation, vibrations, temperature changes, and momentary pressure spikes occur; therefore, it is not only the clamping range that matters, but also how the force is distributed across the entire circumference of the hose.

The GBS W1 features a hinged closure, a 20-mm-wide steel band, and a profile designed to minimize the risk of damaging the hose surface during tensioning and system operation. The FORCE W1 features a 9-mm-wide band, a one-piece bolt housing that increases clamping force, and rounded edges and a smooth inner surface, which reduce the risk of cutting into the rubber.

When selecting a model, check:

• a diameter range that matches the dimensions after installation on the fitting
• a strap width suited to the hose’s stiffness and thickness
• a closure type suitable for the loads and available space
• galvanized protection, i.e., a uniform layer of zinc that limits corrosion

Checking these factors before installation usually helps avoid two problems at once: insufficient clamping force and damage to the hose wall caused by over-tightening.

Which automotive clamps should you choose for a specific system?

GBS W1 clamps are well-suited for flexible hoses, hard rubber hoses, and hoses reinforced with plastic or steel, including those used in vacuum and high-pressure systems. A wider band distributes the pressure more evenly, which is important for stiffer walls and larger diameters.

The FORCE W1 worm-type clamp is the right choice for smaller diameters and in situations where automotive clamps need to fit in a tighter space. The most common mistake is measuring the hose itself before installation or tightening the clamp too much. A properly selected automotive hose clamp ensures a tight seal without damaging the hose.

FAQ

How do you measure the hose diameter after installation?

Measure the outer diameter of the hose fitted to the fitting and select a clamp with a small amount of adjustment—a clamp that fits too tightly makes installation difficult, while one with too much adjustment prevents achieving the proper clamping force.

When should you choose the GBS W1 instead of the FORCE W1 spiral clamp?

The GBS W1, with its 20 mm strap and hinged clasp, distributes pressure more effectively on larger-diameter, stiffer, or reinforced hoses; the FORCE W1 (9 mm) works best for smaller diameters and in tight spaces.

How can you avoid cutting into the hose or causing it to shift during installation?

Match the strap width to the hose’s stiffness, do not over-tighten, use rounded edges and pressure-limiting profiles, and check the zinc coating—this reduces the risk of damage and leaks.
