Superior Insulating Qualities

Polyurethane Insulated Rail Joints feature a tough polyurethane insulation bonded to microalloy joint bar sections. The one-piece polyurethane/steel structure provides reliable circuit isolation and maintains electrical and physical stability in heavy rail traffic and under varying environmental conditions. Our polyurethane is a specially formulated compound which is highly resistant to deterioration by ultra-violet light, ozone, weathering, abrasion, as well as the shocks and flexing stresses of heavy rail traffic. The dense polyurethane material is firmly bonded to the entire rail joint, and provides superior insulation between the joint and the rail. The result is a rigid unitized structure designed to withstand years of heavy-duty service, provide high-dielectric isolation for signal circuits, and require little or no maintenance. Our Insulated Rail Joints meet all current AREMA specifications; test data is available upon request. Designs are available for rail sizes up to 152 pounds. When ordering, please specify rail size, rail drilling, bolt diameter, and elevation.

Minimum Cold Flow – Withstands Vertical and Longitudinal Pressures

Polyurethane Insulated Rail Joints are virtually immune to cold-flow, the most common cause of insulation failure. Because of its bonded-to-steel construction, the joint flexes as a unit with both vertical and horizontal stress. Our tough molded NEMA Grade G-10 end post provides wear-resistant easement between rail ends, and will not cold-flow under high temperature. These joints preserve electrical insulation under the most rugged use and environmental conditions.

Quick and Dependable Delivery

We often have commons sizes in stock, allowing for lead time accuracy and quick deliveries. Our customer service staff interacts with our plant manager on a daily basis, keeping track of the production status of each customer’s order, so that our customers can depend on us for on-time deliveries.

Simple to Install – Saves Time and Money

We mold the bolt hole insulated bushings into each insulated joint bar at our factory, which saves time and reduces frustration for track maintenance personnel when installing the joint on track. Installation of our insulated rail joints is far simpler than with multi-component joints, when the bushings must be field installed, which can be a difficult and wasteful expenditure of a customer’s time and money. This unique design also eliminates the need for our customers to carry additional inventories of bolt hole bushings. Finally, each insulated joint kit includes all the hardware needed for installation and is packaged together to simplify inventory, as well as storage.

Recessed Design Allows For Rail Wear

Our design accommodates wheel flange even after abnormal rail wear without disrupting insulation. We can often accommodate special requests, such as adjusting flange clearance for extraordinary rail wear, making toeless joints, making double insulated joints, etc.
