Product Description
Reliable Watertight Cable Sealing for Float Switch and Control Panel Applications
The SJE float switch cord seal provides a secure, watertight solution for sealing cables entering electrical junction boxes and control panels. Designed for wastewater systems, lift stations, and pump control applications, this cord seal prevents moisture, gases, and contaminants from entering enclosures and damaging electrical components.
Unlike traditional sealing methods, such as duct seal or silicone, this SJE neoprene cord seal delivers cleaner, more reliable installation while maintaining long-term performance in demanding environments.
What Does a Float Switch Cord Seal Do?
A float switch cord seal is used to seal cables where they enter a junction box or control panel. It creates a tight barrier around wires, preventing water and gases from entering the enclosure, while also providing strain relief to protect the cables.
This helps:
Protect electrical connections from moisture damage
Prevent corrosion and system failure
Maintain safe and reliable pump control operation
SJE Float Switch Cord Seal Key Features & Benefits
Watertight Cable Seal
Creates a liquid-tight barrier that prevents water and contaminants from entering electrical enclosures, keeping connections dry and protected.
Neoprene Compression Sealing System
The neoprene plug compresses around cables when tightened, forming a secure and durable seal inside the terminal adapter.
Supports Multiple Float Switch Cables
Available in configurations that accommodate up to four or six cables, reducing the need for multiple entry points.
Built-In Strain Relief
Helps prevent cable wear and damage by securing wires as they enter the enclosure.
PVC Plugs for Unused Cable Positions
Unused holes can be sealed using the included plugs to maintain a watertight connection.
Ground Wire Attachment
Includes a ground wire connected to a stainless steel compression plate for added safety.
Corrosion-Resistant Construction
Built with neoprene seals and stainless steel hardware for long-term durability in wastewater and industrial environments.
Available Models
Four Cable Cord Seal (SJE Part #1008517)
The SJE float switch cord seal is designed to securely seal up to four float switch cables entering a junction box or control panel. Ideal for lift stations and wastewater systems, this watertight cable seal fits into the hub (female) end of any 1 1/2" IPS fitting or inside Schedule 40 or 80 IPS pipes. Tightening the compression nut activates the neoprene seal, creating a reliable barrier that prevents moisture and contaminants from entering the enclosure.
Six Cable Cord Seal (SJE Part #1037126)
This SJE neoprene cord seal accommodates up to six float switch cables, making it ideal for multi-pump or duplex systems. It fits into the hub end of any 2" IPS fitting and provides a secure junction box cable seal for larger installations. Like the four-cable model, tightening the nut compresses the neoprene plug around the cables, forming a durable, watertight seal that protects electrical components.

Why Proper Cable Sealing Matters
Improperly sealed cable entry points can allow water, moisture, and gases to enter electrical enclosures. This can lead to:
Corrosion of electrical components
Short circuits and system failure
Increased maintenance and downtime
Using a watertight cable seal for junction boxes ensures long-term reliability and protects critical pump control systems.
Installation Overview
Installing the cord seal is simple and effective:
Insert the cord seal into the terminal adapter or hub assembly
Feed cables through the neoprene openings
Tighten the compression nut to create a watertight seal
Use included PVC plugs to seal unused openings
Tightening the nut compresses the neoprene plug to prevent gas and moisture from entering the panel.

FAQs
What is an SJE float switch cord seal used for?
It is used to create a watertight seal around cables entering a junction box or control panel, protecting electrical components from moisture and contaminants.
Is this cord seal waterproof?
Yes, the neoprene compression system creates a liquid-tight seal when properly installed.
How many cables can it hold?
Depending on the model, it can hold between one and six cables.
Can this replace duct seal or silicone?
Yes, it provides a cleaner, more reliable alternative to traditional sealing methods.
What happens if not all cable holes are used?
Unused openings can be sealed using the included PVC plugs to maintain a watertight seal.
What types of cables are compatible?
It is compatible with SJOW and SJTW cables in sizes ranging from 18/2 to 14/3.
How do you seal cables in a junction box?
To seal cables in a junction box, insert the cables through a cord seal installed in a terminal adapter, then tighten the compression nut. This compresses the neoprene seal around the cables, creating a watertight barrier that prevents moisture and gas from entering the enclosure.
