Sioux Chief P979-1A PVC Tubular Slip Joint Extension Tube
The Sioux Chief P979-1A is a PVC tubular slip joint extension tube built for rough-in drain and waste connections behind sinks, lavatories, and other fixtures. Its slip joint connection type allows a plumber to adjust tailpiece or trap arm length in the field, closing the gap between a P-trap and a fixture tailpiece, wall stub-out, or drain outlet without cutting or solvent welding. Manufactured from PVC, the tube resists corrosion from wastewater and common household chemicals, making it a reliable, low-cost component for tubular waste and drain assemblies installed during rough-in or remodel plumbing work.
