The Hydro-Quip 2-1/2 inch MBT uni-nut with retainer is designed for compatible 3 inch housing applications where the heater or plumbing connection needs the correct retaining hardware. A uni-nut is useful because it helps secure the threaded connection in a cleaner, more serviceable way while preserving the intended fit of the supported housing.

This replacement is especially useful when the original nut or retainer is cracked, stripped, or too worn to trust during reassembly. Using the correct uni-nut and retainer combination can make the rebuild more complete and more reliable.

The 42-2333B-K is a practical service part when a compatible Hydro-Quip 3 inch housing needs a fresh MBT uni-nut assembly to restore secure connection support.
