202D921-25/225-0 Description

Short technical summary and product information.

The 202D921-25/225-0 is a heat shrink boot manufactured by TE Connectivity. It is designed for shell size 21 and comes in black. The boot is constructed from semi-rigid, irradiated elastomer, providing abrasion, chemical, fluid, and heat resistance, along with flame retardancy. It features an adhesive coating and a lip for strain relief.

 

In its supplied state, the large diameter measures 0.760 in (19.30 mm) and recovers to 0.512 in (13.00 mm). The small diameter supplied is 0.250 in (6.35 mm) and recovers to 0.083 in (2.11 mm). The total recovered length is 2.370 in (60.20 mm), with a large recovered length of 0.618 in (15.70 mm) and a small recovered length of 1.480 in (37.59 mm).

 

This boot is suitable for applications requiring environmental sealing and mechanical protection of cable assemblies and connectors. The adhesive coating ensures a secure bond upon heat recovery, while the semi-rigid material provides structural integrity.
