SKU:S5M182378
The Sierra Marine 182378 Magnetic Drain Screw is a practical replacement component designed to help support routine marine engine and drivetrain maintenance. Its magnetic design helps attract and retain ferrous metal particles that may be present in drained lubricant, giving technicians an additional way to monitor wear during service. Replacing a worn, damaged, or missing drain screw can help maintain the integrity of the drain point and support proper fluid maintenance procedures.
Designed for use in marine service applications, this drain screw is suited to repairs, scheduled maintenance, and replacement of original equipment components when the correct part match has been confirmed. The Sierra Marine brand is recognized for producing aftermarket marine parts intended to meet the service demands of boating environments. Before installation, compare the existing drain screw, thread specification, sealing arrangement, and application requirements to verify compatibility with your engine or component.
Installation should be completed with the lubricant drained and the surrounding area cleaned to help prevent contamination. Inspect the mating surface and sealing components, then install the screw according to the equipment manufacturer’s service instructions and recommended tightening procedure. Do not overtighten, as excessive force can damage threads or the housing. After servicing, check for leaks and confirm that the drain point remains secure during operation. The magnetic tip should be inspected and cleaned during future fluid changes so collected material can be evaluated as part of normal maintenance.
