Campbell OR-28T Replacement O-ring Pitless Adapter

Product Description

The CAMPBELL OR-28T is a replacement O-ring designed for use with pitless adapter assemblies in well water systems. Pitless adapters allow the water supply line to pass through the well casing below the frost line, and the O-ring provides the watertight seal that keeps that connection secure. This part is sold as a 2-piece replacement set. Licensed plumbers and well service contractors install this component during routine maintenance or when an existing O-ring shows signs of wear, cracking, or leakage at the pitless adapter joint.

This O-ring is suited for residential and light commercial well water installations where a pitless adapter connection requires resealing. It is used during well pump service calls, pitless adapter replacements, or scheduled maintenance on submersible pump systems. Having a replacement O-ring on hand reduces downtime when servicing a well that shows signs of a failed seal at the casing wall connection.

• Sold as a 2-piece set for a complete service call or backup supply

Installation Notes

Installation should be performed by a licensed plumber or certified well contractor. Shut off the well pump and relieve system pressure before disassembling the pitless adapter connection. Inspect the seating surface for scoring or debris before installing the new O-ring to ensure a proper seal. Follow all applicable local plumbing codes and well construction standards during service.
