Fernco FT-150 Flexible P-Trap

Flexible P-Trap for 1-1/4" pipe

The Fernco FT-150 is a flexible P-trap built from black rubber for 1-1/4-inch pipe connections. It serves as a drain component in plumbing installations where rigid fittings are difficult to align. The rubber construction allows the trap to absorb vibration and accommodate slight pipe movement without leaking. This design simplifies fitting in confined or awkward spaces under sinks and basins.

Replaces rigid plastic or metal traps

This trap replaces rigid plastic or metal P-traps when pipe alignment is imperfect or when vibration from equipment risks cracking hard joints. The flexible body bridges small offsets and angles that would otherwise require multiple angled fittings. The jump is worth it when the drain line cannot be re-piped to match a standard rigid trap, or when ongoing movement makes a solid joint unreliable. It is not suited for installations that require a fixed, immobile trap geometry or where local code mandates rigid materials.
