Oatey p9790 Slip Joint Extension Tube 1-1/4 X 6 Inches

Product Description

The OATEY p9790 is a polypropylene slip joint extension tube sized at 1-1/4 inches by 6 inches, designed for tubular drain applications under sinks and lavatories. It connects via slip joint ends and includes a TPE washer for a reliable, leak-resistant seal without the need for solvent cement or threading. The white polypropylene construction resists corrosion and is lightweight at approximately 0.102 pounds. Plumbers and drain service technicians install this tube when extending or replacing the drain line between the trap and the drain outlet in residential and light commercial settings.

This extension tube is suited for residential sink, lavatory, and vanity drain assemblies where the existing tailpiece or trap arm does not reach the trap inlet. It is commonly used during sink replacement, cabinet remodels, or drain repair work where additional reach is needed in the tubular drain section. The slip joint design allows for quick, tool-minimal connections and easy future serviceability. Available in 1-1/4-inch sizing to match standard lavatory drain configurations.

Key Features

• Polypropylene construction resists corrosion and chemical exposure common in drain lines
• Slip joint connection on one or both ends allows quick assembly without cement or threading
• TPE washer included for a superior compression seal at the slip joint connection
• White finish blends with standard under-sink drain hardware
• Lightweight at approximately 0.102 pounds for easy handling during installation

Compatibility

Designed as an OEM-style replacement and extension component for standard 1-1/4-inch tubular drain assemblies in residential sink and lavatory installations.

Installation Notes

Installation is performed by licensed plumbers or experienced drain technicians. Shut off the water supply and clear the drain before beginning work. Hand-tighten slip joint nuts, then snug with channel-lock pliers — do not overtighten polypropylene fittings, as excess force can crack the tube or nut. Verify the connection meets local plumbing code requirements under IPC or applicable local amendments before returning the drain to service.
