Casing Insulators / End Seals

casing insulatorsAt road crossings, river crossings and railroad crossings, pipelines are often encased in another larger diameter pipe outside the carrier pipe. Casing spacers are used to keep the casing pipe from touching the carrier pipe. End Seals are used at the end of the casing to seal off the void gap between the casing and carrier pipes. Drinkwater carries the highest quality Casing Insulators and End Seals available on the market today.


An all non-metallic casing isolator/spacer system that uses molded segments to encircle the carrier pipe

Each segment of the Ranger II® casing spacer includes at least one molded-in runner and one slide lock.

High density, injection molded virgin polyethylene casing isolators/spacers designed primarily for smaller diameter steel or polyethylene carrier pipes

Model PE casing spacers/isolators combine excellent safety and performance with durability and easy installation to deliver a high quality solution for a range of small-diameter piping applications. PE Isolators should not be used on concrete carrier pipe.

High temperature-rated casing spacer/isolator for use with small diameter pipes.

Model HT Casing Spacers/Isolators are uniquely formulated to withstand high temperature applications (280° F / 138° C), and are designed primarily for smaller diameter steel or polyethylene carrier pipes (ANSI O.D. pipe without a bell or mechanical joint).

A safe and economic system for sealing the annular space between the carrier pipe and casing to keep the space dry and reduce the risk of corrosion.

Model R End Seals are available in five (5) different sizes to accommodate a wide range of carrier/casing diameter combinations.

A safe and economic system for sealing the annular space between the carrier pipe and casing to keep the space dry and reduce the risk of corrosion.

PSI Model C Custom Pull On end seals are extremely robust, resistant to wide variations in environmental conditions and eliminate the possibility of foreign material entering the opening between the carrier and casing pipes.

A safe and economic system for sealing the annular space between the carrier pipe and casing to keep the space dry and reduce the risk of corrosion.

PSI Model W Wrap Around end seals are extremely robust, resistant to wide variations in environmental conditions and eliminate the possibility of foreign material entering the opening between carrier and casing pipes.

A safe and economic system for sealing the annular space between the carrier pipe and casing to keep the space dry and reduce the risk of corrosion.

Model S Standard Pull On end seals are flexible and easily installed on nominal steel & IPS casing/carrier pipe combinations. PSI Model S end seals are extremely robust, resistant to wide variations in environmental conditions while eliminating the possibility of foreign material entering the opening between carrier and casing pipes.
