Product Identification

Pro Marine RMD is the male side of a quick-disconnect electrical connection. The corresponding RFD female disconnect is available separately.

What This Part Is Used For

Male heat shrink disconnect terminals provide the blade side of a removable electrical connection. The terminal is crimped onto a wire and connected to a compatible female disconnect.

This connection style is commonly used when electrical equipment needs to be removed, inspected, or replaced without cutting the existing wiring.

The heat-shrink insulation helps protect the crimped wire termination, while the male blade allows the electrical connection to be separated from its mating female terminal.

Common Marine Electrical Applications

• Boat electrical wiring repairs
• Marine accessory installations
• Navigation light and courtesy light connections
• Bilge pump accessory wiring
• Marine switch and control circuits
• Electrical panel connections
• Boat wiring harness repairs
• Replacement of damaged electrical terminals
• Serviceable marine equipment connections
• Custom marine wiring projects

These are general application examples. The correct terminal must be selected based on wire gauge, connector dimensions, circuit requirements, and installation conditions.

Important Wire Gauge and Connector Fitment Note

Pro Marine RMD is a red male disconnect intended for 1822 AWG wire and compatible 0.250-inch female disconnect terminals.

Electrical terminals must be matched to the wire gauge and mating connector size. Using the wrong terminal may cause poor electrical contact, overheating, or connection failure.

This product is the male side of the connection. The corresponding female disconnect is sold separately.

Confirm wire gauge, electrical load, terminal dimensions, and mating connector compatibility before installation.

Compatible Wire Sizes and Electrical Applications

Pro Marine RMD is designed for use with appropriately sized electrical wire and a compatible female quick-disconnect terminal.

Connector Configuration

MATCHING FEMALE CONNECTION AVAILABLE

Pro Marine RFD Red Female Heat Shrink Disconnect  25 Pack

Complete your electrical connection with the matching Pro Marine RFD Red Female Heat Shrink Disconnect.

RFD provides the female side of the connection and is designed to mate with a compatible 0.250-inch male blade terminal.

Using the corresponding male and female disconnects allows electrical components to be connected, disconnected, and serviced without cutting the wiring.

Both products are sold in 25-piece packages. Male and female terminals are purchased separately.

Common Symptoms and Replacement Reasons

Male disconnect terminals should be inspected during electrical troubleshooting and replaced when corrosion, physical damage, or poor terminal engagement affects the connection.

Common Reasons to Replace a Male Disconnect

• Corroded or oxidized male blade terminals
• Bent, broken, or damaged connector blades
• Loose or intermittent electrical connections
• Damaged heat-shrink insulation
• Broken or deteriorated wire terminations
• Evidence of overheating or discoloration
• Electrical accessories operating intermittently
• Replacement of damaged wiring harness connections
• Installation of new marine electrical equipment
• Preventive electrical wiring maintenance

Inspect both sides of the connection. A damaged female terminal can also cause poor contact with a male blade. Replace any terminals that are worn, loose, corroded, or overheated.

Installation and Service Tips

Correct crimping and heat-shrink installation help provide a dependable electrical termination in marine environments.

Recommended Installation Practices

• Disconnect electrical power before beginning wiring repairs.
• Confirm the wire size is within the 1822 AWG range.
• Verify that the female mating terminal accepts a 0.250-inch male blade.
• Strip the wire insulation to the appropriate length for the crimp barrel.
• Insert the prepared wire fully into the terminal barrel.
• Use a suitable crimping tool designed for insulated heat-shrink terminals.
• Crimp the connector securely and inspect the mechanical connection.
• Use a controlled heat gun to shrink the insulation around the wire.
• Heat evenly until the sleeve conforms to the wire insulation and forms its seal.
• Allow the connector to cool before applying mechanical stress.
• Inspect the male blade for damage or distortion before connecting.
• Verify the male and female terminals engage securely before restoring power.
