RJ12 Waterproof Straight-Through Inline Coupler

Extend RJ12 Runs Without Sacrificing a Watertight Seal

Splicing two RJ12 cables together in a wet or humid grow environment normally risks water finding its way into the connection over time, which can cause an intermittent or failed link right when it's least convenient. The TrolMaster ECW-1 extends the connection between two RJ12 cables while avoiding that risk, using sealed waterproof connectors that keep water out entirely.

Rated IP68, it maintains a long-lasting, stable, high-performance connection between controllers, sensors, and devices even in consistently damp conditions.

Key Features & Benefits

• IP68 Rated — seals against water intrusion at a level suited to wet environments.
• Straight-Through Design — joins two RJ12 cables in line without a splitter or branch.
• Stable, High-Performance Connection — maintains signal quality between controller and connected devices.
• Compact Housing — installs easily along an existing cable run.

Who Should Use the ECW-1 Inline Coupler

TrolMaster users who need to extend an RJ12 cable run in a wet or humid environment, without sacrificing connection reliability, are the intended buyer for the ECW-1. It's the right choice specifically where a standard unsealed splice would be exposed to water over time.

About TrolMaster

TrolMaster rates the ECW-1 to IP68, a step above the IP65 and IP67 ratings used elsewhere in its cabling lineup, reflecting the Sacramento, California company's approach of matching connector protection to how exposed a given splice point actually is. Choosing the right IP rating for a splice location is part of a durable Hydro-X installation.
