Watertight Door Upgrade Kits (MACHALT 526)

Current watertight door dog latch designs fail to function properly due to the presence of paint or other debris such as corrosion products on the exposed area of a floating bushing. The corrosion products are formed primarily from corrosion of a carbon steel sleeve, which houses the assembly and is welded to the door.

The DeNOVUS™ Watertight Door Dog Repair Kit (MACHALT 526) replaces the prior wax filling and silicone oil with E-1270EPL and the addition of an external shield. The new design has dramatically improved the cyclic corrosion performance of the water tight door dog latch. The new design has dramatically improved the cyclic corrosion performance of the water tight door dog latch.
