Pro Marine Red Female Heat Shrink Disconnect 1822 AWG  25 Pack

Pro Marine Marine-Grade Heat Shrink Electrical Connectors

Pro Marine RFD Red Female Heat Shrink Disconnect – 18–22 AWG – 25 Pack

The Pro Marine RFD Red Female Heat Shrink Disconnect is a fully insulated, marine-grade electrical terminal designed for creating secure, removable electrical connections in marine wiring systems.

These red female quick-disconnect terminals feature a heat-shrink insulation sleeve with an adhesive-lined interior that helps protect electrical connections from moisture, corrosion, salt spray, and vibration.

Designed for 18–22 AWG wire, these terminals use a standard 0.250-inch (1/4-inch) female disconnect connection that mates with a corresponding male quick-disconnect terminal.

Unlike permanent electrical connections, quick-disconnect terminals allow components to be disconnected and reconnected for servicing, troubleshooting, maintenance, or replacement without removing the crimped terminal from the wire.

Each package contains 25 red female heat shrink disconnect terminals, making them ideal for marine electrical repairs, equipment installations, and wiring projects.

Product Identification

The following Pro Marine part numbers identify the female disconnect and the separately available matching male disconnect.

What This Part Is Used For

Female heat shrink disconnect terminals are used to create removable electrical connections between marine wiring and compatible male terminals.

The female terminal is crimped onto the end of a wire and then connected to a corresponding male disconnect.

Once the heat-shrink insulation is properly recovered around the wire, the adhesive-lined sleeve helps protect the crimped wire termination from moisture and environmental exposure.

The quick-disconnect connection allows electrical components to be removed or serviced without cutting the wire or removing the crimped terminal.

Common Marine Electrical Applications

• Boat electrical wiring repairs
• Marine accessory installations
• Navigation and courtesy lighting connections
• Bilge pump wiring connections
• Marine switch and control wiring
• Electrical panel and accessory connections
• Boat wiring harness repairs
• Electrical equipment replacement
• Marine electronics accessory wiring
• Serviceable electrical connections requiring periodic disconnection

These are general examples of wiring applications. Always confirm that the terminal size, wire gauge, current requirements, and connection style are appropriate for the specific equipment.

Important Wire Gauge and Connector Fitment Note

Pro Marine RFD is a red female disconnect intended for 18–22 AWG wire and a 0.250-inch male disconnect terminal.

Electrical terminals must be selected according to the wire gauge and mating terminal dimensions. Using an incorrect connector size may result in an unreliable electrical connection.

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

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

Compatible Wire Sizes and Electrical Applications

The Pro Marine RFD female heat shrink disconnect is designed for use with the following wire sizes and terminal configuration.

MATCHING MALE CONNECTION AVAILABLE

Pro Marine RMD Red Male Heat Shrink Disconnect – 25 Pack

Need the other side of your electrical connection?

Pro Marine USA also offers the RMD Red Male Heat Shrink Disconnect, designed to provide the male side of a removable electrical connection.

Pair the RFD female disconnect with the corresponding RMD male disconnect when building or repairing marine electrical connections.

Both products are sold in convenient 25-piece packages.

The male and female terminals are purchased separately, allowing customers to order the quantities needed for their wiring projects.

Common Symptoms and Replacement Reasons

Marine electrical terminals may require replacement when corrosion, mechanical damage, or poor electrical contact affects the connection.

Common Reasons to Replace a Female Disconnect

• Corrosion on existing electrical terminals
• Loose or damaged female disconnect connections
• Damaged wire insulation near the terminal
• Broken or deteriorated electrical connectors
• Intermittent electrical accessory operation
• Electrical connections exposed to moisture
• Replacement of damaged wiring harness terminals
• Installation of new marine electrical accessories
• Conversion from damaged or unsuitable connectors
• Preventive replacement during electrical wiring repairs

Electrical problems can have multiple causes. Inspect the wiring, terminal condition, mating connector, and connected equipment before replacing components.

Installation and Service Tips

Proper installation is important for maintaining a secure electrical connection and obtaining the intended moisture protection from the heat-shrink insulation.

Recommended Installation Practices

• Disconnect electrical power before beginning wiring repairs or installation.
• Confirm the wire is within the 18–22 AWG range.
• Select a compatible 0.250-inch male disconnect for the mating connection.
• Strip the wire insulation according to the terminal installation requirements.
• Insert the prepared wire fully into the terminal crimp barrel.
• Use a crimping tool and die appropriate for insulated heat-shrink terminals.
• Crimp the terminal securely and inspect the completed connection.
• Apply controlled heat using a suitable heat gun to recover the insulation sleeve.
• Heat the sleeve evenly until it conforms around the wire insulation and the adhesive seal is properly formed.
• Allow the terminal to cool before handling or applying mechanical stress.
• Inspect the finished connection for exposed wire, incomplete shrinkage, or damaged insulation.
• Verify the male and female disconnects engage securely before restoring power.

View Pro Marine RMD Male Disconnect

Are these connectors waterproof?

The adhesive-lined heat-shrink sleeve is designed to provide an environmental seal around the crimped wire termination when properly installed.

The detachable male-to-female connection itself should not be considered waterproof unless the complete connection assembly is specifically rated for that application.

Can these connectors be disconnected and reused?

The male and female disconnect interface is designed to be separated and reconnected during equipment servicing.

However, the crimped terminal is intended to remain attached to its wire. A removed or damaged crimp terminal should be replaced rather than recrimped.

How many female disconnects are included?

Each Pro Marine RFD package contains 25 female heat shrink disconnect terminals. Male terminals are sold separately.

Is there a discount for purchasing multiple packs?

Yes. Purchase 4 packs of RFD female disconnects for a total of 100 connectors and save 10%.

Can these terminals be used on boats and outboard wiring?

These terminals can be used in suitable marine electrical wiring applications, including accessory circuits and serviceable equipment connections.

They are not specific to any particular engine manufacturer or horsepower range. Confirm the wire gauge, terminal dimensions, electrical load, and environmental requirements for the installation.

Do I need a special tool to install these connectors?

Installation requires a suitable crimping tool for insulated terminals and a controlled heat source, such as a heat gun, to recover the heat-shrink insulation.

Follow the recommended crimping and heating procedures.
