Pvc Fittings cs-8-16 Hdpe Wall Sleeve 8.21 in Id

Product Description

The PVC FITTINGS cs-8-16 is a Century Line plastic wall sleeve manufactured from high-density polyethylene (HDPE). It is designed to line and protect wall penetrations in construction, plumbing, and industrial piping applications. The sleeve measures 8.21 inches inner diameter and 16 inches in length, providing a smooth, chemically resistant passage for pipes routed through concrete or masonry walls. At 4.8 pounds, it is approximately one-eighth the weight of a comparable steel sleeve, making it manageable for a single installer. Plumbers, pipefitters, and general contractors typically specify this product where chemical resistance and lightweight handling are priorities.

This wall sleeve is suited for residential, commercial, and light industrial installations where pipes penetrate foundation walls, slabs, or concrete block. Its HDPE construction makes it appropriate for environments exposed to acids, alkalis, and common organic solvents. Typical installations include drain, waste, and vent penetrations as well as process piping in facilities where corrosive exposure is a concern. The 8.21-inch inner diameter accommodates large-diameter pipe runs that require a protective sleeve through a structural wall opening.

Key Features

• HDPE construction provides excellent resistance to acids, alkalis, and organic solvents
• 8.21-inch inner diameter accommodates large-diameter pipe penetrations
• 16-inch sleeve length suits standard wall thicknesses and concrete forms
• 4.8-pound weight — roughly one-eighth the weight of steel — allows single-worker installation
• Smooth interior bore reduces friction and supports clean pipe routing

Compatibility

Designed as an OEM-style wall sleeve for large-diameter pipe penetrations through concrete, masonry, or block walls in plumbing and industrial piping systems.

Installation Notes

Wall sleeves of this type are typically installed by licensed plumbers or pipefitters during rough-in, prior to concrete placement or wall finishing. Verify the rough opening diameter matches the sleeve outer dimension before setting. Follow applicable local building codes and IPC requirements for sleeved penetrations, including firestopping and annular space sealing where required. Do not use solvent adhesives or mechanical fasteners that are incompatible with HDPE.
