Stainless Steel Casing Insulators
Model M-6-SS, M-8-SS and M-12-SS casing insulators are made of 14 gauge, grade 304 stainless steel. They feature an extra heavy duty vinyl liner, assuring double insulation.
Fusion Coated Epoxy Insulators
Model M-6-FCE, M-8-FCE and M-12-FCE casing insulators are made of 14 gauge steel, with 10 mil epoxy coating. The runners are abrasion resistant, and are attached mechanically with bolts. The bolt heads are TIG welded to the band. The extra heavy duty vinyl liner assures double insulation. Skids are available in both polyethylene and phenolic.
Fusion Coated Polyvinyl Insulators
Model M-6-FCV, M-8-FCV and M-12-FCV casing insulators are made of 14 gauge steel, with 10 mil vinyl coating. The runners are abrasion resistant, and are attached mechanically with bolts. The bolt heads are TIG welded to the band. The extra heavy duty vinyl liner assures double insulation. Skids are available in both polyethylene and phenolic.

Model P Insulator
Ideal for applications using small pipe sizes, as small as 1”. Calpico Model P insulators are made of high density (linear) polyethylene. This material provides high impact strength, a low coefficient of friction and excellent abrasion resistance.
The high insulating value and low water absorption characteristics of the non-filled, polyethylene assures negligible current loss, positive insulation and complete cathodic protection.

Model PX Insulators
Model PX injection molded plastic casing insulators are ideal to keep carrier pipe isolated from casing. This model is manufactured from polyethylene, which provides high impact strength and a low co-efficient of friction. Non-deteriorating polyethylene lasts indefinitely inside the casing. Excellent dielectric resistance and low moisture absorption for minimal electric current loss and no impairment of cathodic protection. The only metal is the hardware. A grooved inner surface prevents slippage and damage to any coating the pipe may have. Model PX insulators are light in weight, economical, easy to handle, and easy to install. No special tools are needed.
