Platinum Tools 740C Waterproof RJ45 Splice Coupler

Product Description

The PLATINUM TOOLS 740C is a waterproof RJ45 splice coupler designed to create a secure, female-to-female connection between two Ethernet cables. This inline coupler joins two RJ45-terminated cables end to end while providing protection against moisture intrusion, making it suitable for installations where standard couplers would fail. Electricians, low-voltage technicians, and network installers use this fitting when extending Cat cable runs in locations exposed to weather, irrigation spray, or condensation. The female-to-female configuration accepts standard RJ45 plugs on both ends for a straightforward connection.

This coupler is suited for outdoor structured wiring, security camera runs, access control systems, and other low-voltage network applications where the connection point may be exposed to moisture. It is commonly used at exterior junction points, in-wall splice locations with moisture risk, and in light commercial or residential installations where a reliable, weather-resistant inline connection is needed. It is sold as a single unit.

Key Features

• Waterproof construction protects the RJ45 connection from moisture and environmental exposure
• Female-to-female configuration joins two RJ45-terminated Ethernet cables inline
• Suitable for outdoor and moisture-prone installation environments
• Compact inline form factor requires no additional tools for mating
• Sold individually for single-point splice applications

Compatibility

Designed as an inline splice coupler compatible with standard RJ45-terminated Ethernet cables, including Cat5e and Cat6 patch cables with male RJ45 connectors.

Installation Notes

Installation is performed by low-voltage technicians or electricians working with structured cabling systems. Ensure both RJ45 plugs are fully seated and latched before closing or securing the coupler housing to maintain the waterproof seal. Follow local low-voltage wiring codes and any applicable TIA-568 cabling standards when planning the cable run. Do not force incompatible connector styles into the coupler ports.
