High density (linear), injection molded virgin polyethylene casing isolators/spacers provide positive insulation, high abrasion resistance and low coefficient of friction for a wide variety of double containment carrier/casing pipe applications. They are extremely light in weight and easy to handle during installation.

A ribbed inner surface prevents slippage and guards against carrier pipe coating damage while the outer surface may include any one of several molded runners to accommodate 2" (50.8mm) x 4" (101.6mm) or larger carrier/casing differentials.

One piece solid molded segments provide for maximum load bearing. Hardware includes cadmium plated steel studs, nuts and washers. A screwdriver is the only tool needed for installation.



  • Ribbed inner surface prevents slippage & guards against coating damage.
  • Molded from virgin polyethylene material.
  • Lightweight for ease of handling and installation.
  • Screwdriver is only tool needed for installation.
  • Model available with non-metallic hardware.
  • Eliminates the need for grout, blown sand or pea gravel.




Targeted Used - Energy

 For carrier pipe diameters (Nominal Steel & IPS) ranging from 3/4” (19.1mm) to 12” (30.48cm)

 For carrier pipe insertion lengths up to 300' (91.4M)

 Spacing Recommendation: Max 8’ (243.8cm) between spacers, Max 2’ (61.0cm) from casing pipe end.

 Recommended End Seals: Model C, S, W, R and FW.

*Model PE Casing Spacers are designed primarily for smaller diameter steel or polyethylene carrier pipes (ANSI O.D. pipe without a bell or mechanical joint). We do not recommend that they be used on any carrier pipe over 12" (30.48cm) in diameter or for installations over 300 feet (91.4M) long without consulting with PSI. PE Isolators should not be used on concrete carrier pipe.
