6" x 1" Cast Iron Submersible Split Well Seal

6" x 1" Cast Iron Split Well Seal – Engineered for Reliable Submersible Installations

The 6" x 1" Cast Iron Submersible Split Well Seal is built for demanding groundwater applications. Designed for use at the top of a 6" well casing, this seal creates a secure barrier between the drop pipe and power cable, protecting against contamination and physical strain on system components. Its split design enables easy installation or maintenance without having to disconnect plumbing or electrical wiring.

Performance Features

• Heavy-Duty Construction: Cast iron upper plate and lower support plate provide strength and corrosion resistance for long-term use.
• Watertight Compression Seal: Rubber gasket creates a tight seal around pipe and cable to prevent debris, pests, or surface water from entering the well casing.
• Split Design: Allows retrofit installations or quick field service without pipe removal, saving time and labor.
• Drop Pipe and Cable Accommodation: Designed for 1" pipe size with dedicated pass-through for pump wire leads.
• Mechanical Fastening: Threaded bolts ensure uniform compression and long-term gasket performance.

Technical Specifications

• Seal Size: 6" casing x 1" drop pipe
• Material: Cast iron (upper/lower plates), rubber gasket (sealing element)
• Type: Submersible split well seal
• Application: For use in 6" diameter well casings with submersible pump installations
• Cable Entry: Separated slot to guide pump wire through seal without damage

Professional Use & Installation

This well seal is designed to meet the needs of contractors installing submersible pumps in municipal, agricultural, or residential water systems. A proper seal at the casing head is critical for maintaining sanitary conditions and protecting internal components. The split configuration makes this model ideal for system retrofits, pump replacements, or service calls.

For optimal results, installation should be handled by trained professionals using appropriate torque settings on all compression bolts to ensure a uniform seal. Be sure to verify cable clearance and gasket positioning before tightening.

Applications

• 6" casing wellheads with submersible pumps
• Installations requiring retrofit or replacement without disassembling piping
• Projects where code-compliant sealing at the wellhead is required

Contractor Insight

Well seals like this one are not just hardware—they're essential to system reliability. This model protects against well contamination, prevents stress on drop pipes and wire, and simplifies future service. Its cast iron body holds up in rough field conditions, while the split design keeps your crew efficient when time is tight.
