An Onspot Diaphragm is a flexible membrane that separates the air cylinder from the hydraulic fluid in an Onspot automatic tire chain system. The diaphragm is responsible for transferring the force of the compressed air to the hydraulic fluid, which in turn powers the system’s chain deployment mechanism.
- The tire chains do not deploy properly or at all.
- There is a leak of air or hydraulic fluid from the air cylinder.
- The air cylinder is making excessive noise.
