Ancor Adhesive Lined Heat Shrink Tubing (ALT) - 3/16" x 12" - 10-Pack - Black

The Ancor Adhesive Lined Heat Shrink Tubing (ALT) in 3/16" x 12" – 10-Pack – Black is a marine-grade electrical connectivity solution designed for harsh-environment applications where moisture, salt spray, and chemical exposure demand superior waterproofing and strain relief. Each pack contains ten 12-inch sections of cross-linked polyolefin tubing rated for 20–12 AWG wire, shrinking from 3/16" to 1/16" diameter when heat-activated. This product is essential for professionals working in saltwater environments, offshore platforms, marine vessels, and corrosive industrial settings where standard PVC tubing fails to provide adequate protection.

The heat-activated adhesive lining creates an impervious seal against saltwater, mineral oils, acids, and prolonged UV exposure—critical for subsea cable terminations, navigation system wiring, and deck-mounted electrical assemblies. Cross-linked polyolefin construction outperforms PVC in both mechanical strength and flame resistance, meeting the demands of marine electrical codes and offshore safety standards. The adhesive-lined design simultaneously addresses two failure points: environmental ingress and mechanical strain at the connection, eliminating the need for secondary sealants or strain-relief boots. Wire range compatibility (20–12 AWG) covers standard marine instrumentation and auxiliary power circuits.

This tubing is specified for marine electrical repair, commercial fishing fleet maintenance, offshore drilling operations, and saltwater-exposed industrial wiring. The 12-inch length per section provides flexibility for single-wire wrapping or bundled multi-conductor applications. Technicians and electricians working in corrosive maritime environments, as well as field personnel maintaining critical communication and navigation systems aboard vessels, rely on Ancor ALT tubing to ensure long-term connection integrity without corrosion-induced failure or signal degradation.
