Why Are Double Bridge Clamps Recommended for Vulcano® Polyurethane Hoses?
When choosing a polyurethane hose, it is important to consider not only its abrasion resistance, flexibility, or diameter, but also how it will be secured to the fitting. An incorrectly selected clamp can lead to leaks, hose deformation, or a shorter service life.
Vulcano® polyurethane hoses are reinforced with a steel spiral, which means that standard clamps are not always suitable for them. A conventional clamp may compress the hose unevenly, apply excessive pressure between the spiral turns, or damage the hose wall. As a result, the connection may lose its tightness, and the hose may wear out faster.
This is why bridge clamps are most often recommended for these hoses, as they are designed for hoses reinforced with spiral wire.
What Are the Benefits of Double Bridge Clamps?
Bridge clamps adapt better to the hose construction and help distribute the clamping force more evenly. This is especially important when the hose is used in dust extraction systems or for transporting sawdust, granules, abrasive materials, or bulk materials.
Main advantages:
- they compress the hose more evenly around the entire fitting;
- they reduce the risk of damage to the spiral and hose wall;
- they help ensure a more reliable seal;
- they reduce the likelihood of the hose slipping off or becoming deformed;
- they are especially suitable for larger-diameter polyurethane hoses.
When Should Double Bridge Clamps Be Used?
Bridge clamps are recommended when the hose is reinforced with a spiral, when the connection is exposed to vibration or movement, or when reliable sealing is essential. They are also useful for larger-diameter hoses, where incorrect fastening can more quickly lead to leaks or downtime.
A common mistake is choosing a clamp based only on diameter. It is also important to evaluate the hose construction. If the hose has a spiral, the fastening solution must be suitable for that specific surface.
Why Is This Important for Connection Reliability?
A correctly selected clamp helps maintain system tightness, protects the hose from damage, and contributes to a longer service life. This is why bridge clamps are recommended for Vulcano® polyurethane hoses — they are a practical solution that helps prevent unnecessary failures and downtime.
