CES-2A-F2 - 

Raychem CES Series
TE Connectivity CES series heat-shrinkable cable entry seals provide a watertight, fume-tight seal where cables enter connection boxes, bulkheads, or other enclosures. The CES series are available in two basic types: standard and threaded. To meet sealing requirements, all CESs have factory-applied adhesive that provides the seal to wire and cable jackets. The standard CES for thin-wall enclosures consists of a three-part assembly: a rigid nylon nut, an O-ring, and a heat-shrinkable molded body. The CES for threaded-hole applications is a one-part assembly that combines a tapered national pipe thread (NPT) in rigid nylon with a heat-shrinkable molded body.
