Larsen Supply Co. 883582 Pvc Flex Slip Joint Extension Tube

Product Description

The LARSEN SUPPLY CO. 883582 is a flexible PVC slip joint extension tube designed for 1-1/2 inch kitchen drain applications. It extends the drain connection from 5.75 inches to 11.375 inches, making it a practical solution when standard fixed-length tubes fall short during drain assembly or rough-in adjustments. The tube is white in color and constructed from PVC. Each unit ships with one slip nut and one washer, so no additional hardware is needed for a basic slip joint connection. Plumbers and drain service technicians install this type of fitting during sink drain rough-in, trap arm repositioning, or drain repair work.

This extension tube is suited for residential kitchen sink drain installations where the distance between the trap arm and the drain basket tailpiece requires a flexible, adjustable connection. The slip joint design allows for quick, tool-assisted hand-tightening without adhesives or solvent welding. It is appropriate for use in under-sink cabinet configurations where rigid tubing does not accommodate alignment tolerances. The white PVC finish is common in residential kitchen and light commercial sink applications.

Installation Notes

Installation is performed by a licensed plumber or qualified drain technician. Before beginning, shut off water supply to the sink and place a bucket under the trap to catch residual water. Hand-tighten the slip nut to seat the washer, then snug with slip-joint pliers — do not overtighten PVC slip fittings, as excess force can crack the nut or deform the washer. Local plumbing codes under the IPC or applicable state amendments may govern drain assembly materials and configurations; verify compliance before installation.
