Spinlock re-arming kit (20g) for Deckvest CENTO Junior lifejacket harness.

The Deckvest CENTO uses the UML MK5 Inflator. This is a water sensitive activation system that uses a compressed paper capsule which dissolves when wet which then releases a spring to puncture the CO2 cylinder.

The cap (Black) is designed so that only water flowing upwards through the unit will cause it to activate. Water, spray and rain running down the jacket will not cause activation.
