Cresline 51165 Pvc Cellular Core Pipe 8 in X 20 Ft Sch 40

Product Description

The CRESLINE 51165 is an 8-inch nominal Schedule 40 PVC cellular core DWV pipe manufactured to ASTM F891 standards. Cellular core construction uses a foamed PVC inner layer between solid PVC skins, reducing overall weight compared to solid-wall pipe while maintaining the stiffness and pressure ratings required for drain, waste, and vent applications. Each stick runs 20 feet in length with an outside diameter of 8.625 inches and a wall thickness of 0.322 inches. Licensed plumbers and underground utility contractors install this pipe in gravity-drain systems where reduced weight eases handling in long runs and deep excavations.

This pipe is suited for residential and light commercial drain, waste, and vent systems. The IPS (Iron Pipe Size) connection type allows it to integrate with standard Schedule 40 PVC fittings across DWV assemblies. The white color and smooth interior surface are consistent with above-grade and below-grade interior plumbing installations. It is typically used in horizontal drain runs, vertical stacks, and building sewer laterals where gravity flow governs the design.

Key Features

• ASTM F891-compliant cellular core PVC construction reduces pipe weight vs. solid-wall Schedule 40
• 8-inch nominal size with 8.625-inch outside diameter and 7.981-inch inside diameter
• 0.322-inch wall thickness meets Schedule 40 dimensional requirements
• IPS connection type compatible with standard Schedule 40 PVC DWV fittings and solvent-weld joints
• 20-foot stick length minimizes field joints on long straight runs
• White PVC suitable for above-grade and below-grade DWV applications

Compatibility

Designed as an OEM-style Schedule 40 IPS replacement or new-installation pipe for residential and commercial PVC DWV systems using standard 8-inch solvent-weld fittings that conform to ASTM F891 dimensional standards.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local codes governing DWV pipe sizing, slope, and support spacing. Joints are made with solvent cement rated for PVC cellular core pipe per manufacturer instructions. Trench bedding and backfill must follow engineered specifications to prevent point loading on the pipe wall. Never use this pipe for pressure applications or systems outside its DWV rating.
