Campbell Pitless Well Seal - Blank, Sub & Single Hole - 6 to 12 in Casing

Campbell Pitless Well Seals seal the top of the well casing where a pitless adapter carries the discharge line out through the casing wall below the frost line. They keep surface water, debris, and contaminants out of the well while allowing the drop pipe and wiring to pass through.

This listing covers three configurations:

• Blank (Jet) — solid top plate with no drop-pipe penetration, for jet and pitless-adapter installations.
• Submersible — blank plate configured for submersible pitless-adapter systems.
• Single Hole — one drop-pipe penetration sized to the pipe.

Cast iron construction. Select your casing inside diameter and, for single-hole seals, the drop pipe size. If you are unsure of the correct casing ID or configuration, contact us for engineering-led selection before ordering.

Measure the actual inside diameter of your well casing and match it to the Casing Size (ID) option. For single-hole seals, match the Drop Pipe Size to your drop pipe outside diameter.
