2:1 Thin Wall Heat Shrink Tubing – Philmore 45-814B-BL

Philmore 45-814B-BL — 2:1 Thin Wall Heat Shrink Tubing

The Philmore 45-814B-BL is a 2:1 thin-wall heat shrink tubing designed to provide electrical insulation and mechanical protection for wire joints, splices, and terminal connections. Heat shrink tubing slides easily over cables and components, then contracts when heated to form a close-fitting, insulating barrier that resists abrasion and moisture ingress in everyday installations. This product helps maintain installation quality by offering neat, consistent insulation that improves strain relief and protects conductors from short circuits and environmental exposure. Technicians and installers will appreciate the time-saving application compared with liquid insulators or bulky sleeving, while OEM and MRO buyers can use it to standardize repair and assembly processes. The tubing is appropriate for use on a wide range of insulated conductors and in control panels, harness assemblies, and field cable repairs. Because manufacturer specifications vary by size and color, confirm the exact diameter and length needed before ordering to ensure proper fit for terminals and cable bundles.

Specifications:

• Manufacturer: Philmore
• MPN: 45-814B-BL

Typical Applications:

• Insulating soldered joints and wire splices in residential and commercial electrical work
• Protecting cable terminations in AV, security, and network installations
• Bundling and color-coding wiring in control panels and OEM assemblies
• Field repairs for MRO and service technicians

Installation Example:

• Slide an appropriately sized length of tubing over the wire or splice, apply controlled heat with a heat gun while rotating the assembly, and allow the tubing to shrink evenly until it forms a snug, continuous seal around the joint. For multi-conductor bundles, use tubing sized to maintain clearance from terminals and connectors.
