Bsc Preferred DIB956 Plastic Slip Joint Nut 1-1/4 Inch

Product Description

The BSC PREFERRED DIB956 is a 1-1/4 inch plastic slip-joint nut used in drain line assemblies under sinks and in similar residential and light commercial plumbing applications. The slip-joint design allows for tool-free hand-tightening, creating a removable and serviceable connection between drain components. At 0.03 pounds, it is a lightweight, single-piece fitting suited for quick replacement during drain repairs or new installations. Plumbers and experienced DIYers stock these as a standard consumable when servicing P-traps, drain extensions, and basket strainer tailpieces.

This fitting is commonly used in residential bathroom and kitchen sink drain systems. It threads onto standard 1-1/4 inch slip-joint drain tubing and trap components, providing a watertight compression seal against a neoprene or rubber washer. Typical install scenarios include P-trap replacement, drain line rerouting, and repair of stripped or cracked existing nuts on under-sink drain assemblies.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson in accordance with applicable local plumbing codes. Shut off the water supply and place a bucket under the drain assembly before disassembling existing connections to avoid spills. Thread the nut onto the drain tube by hand until snug, then confirm the compression washer is seated correctly before final tightening. Avoid over-tightening plastic slip-joint nuts, as excess force can crack the nut or distort the washer seal.
