大多数软管都是由橡胶制成的。一些软管被加固，但橡胶仍然是主要的建筑材料。橡胶提供了合适的功能组合 - 它可以轻松地扩展并与温度波动，相对较轻，而且价格合理。

The rubber is susceptible to wear and tear, mainly due to heat exposure. As rubber is heated and cooled over and over again, it loses its elasticity and becomes brittle, which leads to cracking.

Can Cracked hoses be repaired?

Cracked hoses cannot be repaired. They must be replaced.

它们可以用胶带或类似的东西暂时加固，以使您能够达到专业更换的机械师。用破裂的软管驾驶是灾难的邀请 - 吹散的散热器软管可能会使您滞留在路边。破裂的软管也会导致发动机中的温度升高，以至于它实际上会损坏发动机。

The best option is to ensure that all of your hoses are being inspected by a professional during your regular maintenance. This should include both a visual inspection for cracks and obvious signs of wear and tear, but it should also include a touch test to feel for brittle and “crackly" hoses.
