Raychem CRSM wraparound sleeves are fast and permanent cable repair sealing system. The sleeve is quickly fitted in place by means of its rail and channel closure. The sleeve is heated using a regular gas torch causing it to shrink in diameter conforming tightly to the substrate. The heat activated sealant coating inside the sleeve melts and flows into the interstices and bonds to the various cable jackets – plastics, rubber, lead, aluminium – to create an excellent moisture seal. If desired, the channel can be cut after the sleeve has cooled to ambient temperature. CRSM is semi-rigid and exhibits excellent abrasion and corrosion properties. Features & Benefits • Wraparound rail and closure system enables repair any where along the length of the cable. • The stainless steel channel converts the Wraparound to a tubular configuration. • Pre-coated sealant eliminates the need for any additional sealing material. • Heat-shrink property enable tight conformity to irregular substrates and provides a wide use range. • CRSM can also be used as primary insulation restoration for low voltage cable joints.
