Expandable Braided Sleeving

MONOFLEX® PET TW is similar to our standard PET sleeving but has a tighter construction giving it it’s “tight weave” name. The tighter weave provides increased density, high abrasion resistance, and has higher coverage all of which are ideal factors for applications where snag resistance and protection is needed. The particular deign and expandability allows for simple and efficient installation over connectors and is durable against heat operating up to 125°C.

MONOFLEX® PET TW is currently unavailable for purchase online; please reach out through the button below for purchasing assistance from our Sales & Marketing Team or to learn more about the color variety and multiple sizes we offer.

The suggested application is provided by Atkins & Pearce merely as an additional tool to assist the customer in making an appropriate expandable sleeving selection. This is only provided to serve as suggestions of expandable sleeving 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 a sleeve’s flexibilities, resistances, and treatment. Final sleeving 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 expandable sleeving product testing and data validation cannot be overstated.

As the customer, you and your company are responsible for appropriately testing all Atkins & Pearce expandable sleeving 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.
