With excellent dielectric resistance and low moisture absorption for minimal electric current loss and no impairment of cathodic protection, polyethylene spacers and insulators are an economical choice for use on all plastic pipe, metal pipe up to 12" in diameter and smaller ductile pipe.

Polyethylene casing spacers and insulators are manufactured by injection molding using polyethylene, which provides high impact strength and a low coefficient of friction.

Two halves are used to construct the 1" through 12" spacers. Runner height for polyethylene spacers can be increased to provide clearance for bell and spigot connections. Ideal for most sizes of schedule 40 and schedule 80 PVC, C 900, SDR 21 & 26, Ultra-Rib and more. They are only recommended for use on 12” and smaller ductile iron pipe.

Polyethylene casing insulators are recommended for every 6 to 8 feet of pipeline. Molded into the inner surface of the casing insulators are grooves which prevent slippage of any carrier pipe coating. Lightweight, economical and easy to install, APS Polyethylene Casing Insulators require only a screwdriver for installation. Do not exceed 35 in-lbs of torque.

Sizes are available from 1" through 12" with a standard runner height of 1". Casing Insulators from 1" through 12" are constructed of two halves.


Non-metallic bolts and nuts are also available for our polyethylene insulators.
