Ben-Har® 1258

Electrical Sleeving & Tubing

Ben-Har® 1258 is a tough and extremely flexible, unsupported silicone rubber tubing with outstanding electrical and thermal properties.  Its outstanding flexibility comes from the combination of a proprietary silicone rubber compound and a special extrusion technique.  Ben-Har® 1258 does not become stiff or brittle over time and tolerates moisture and sunlight, that normally deteriorate most natural or synthetic elastomers.

Suggested Application

Ben-Har® 1258 fits snugly over irregular contours such as splices, components and fittings, protecting them against vibration damage and insuring permanent positioning.  It is ideal for a variety of applications, including hot fluid conveying, acoustical tubing, high-temperature cushioning, high violate and high temperature flexible covering, modest pressure hydraulic or pneumatic lines and thermal covering and protection.

DISCLAIMER

The suggested application is provided by Atkins & Pearce merely as an additional tool to assist the customer in making an appropriate electrical sleeving and tubing selection. This is only provided to serve as suggestions of electrical sleeving and tubing that may be appropriate based on certain criteria and should not be relied upon as determinative or as a substitute for customer testing.

Many variables exist in an electrical sleeving or tubing’s flexibilities, resistances, and treatment. Final electrical product selection should always be confirmed through the customer’s own testing process to determine if a particular product is the correct choice for a particular system. Atkins & Pearce is not responsible for selections made by the customer using any of the reference material provided. For optimal performance in specific systems, we strongly recommend that customers conduct exhaustive electrical tests in their own lab and consider retaining samples for their future internal reference. The importance of electrical product testing and data validation cannot be overstated.

As the customer, you and your company are responsible for appropriately testing all Atkins & Pearce electrical sleeving and/or tubing used in your application and for making the final selection based upon meeting appropriate safety and electrical standards. Atkins & Pearce makes no representation or warranty, expressed or implied, at law or in equity, in respect of the information provided, including, without limitation, with respect to merchantability or fitness for any particular purpose, which representations or warranties are hereby expressly disclaimed.
