What temperature is needed to shrink this tubing?

PVC heat shrink tubing typically activates at temperatures around 70–90°C (158–194°F). A heat gun set to low or medium is recommended. Avoid open flames, as they can cause uneven shrinking or damage the tubing.

Is this tubing suitable for outdoor or wet environments?

PVC heat shrink tubing generally provides basic moisture resistance and is suitable for light indoor and sheltered outdoor use. For fully waterproof or submersion applications, an adhesive-lined (dual-wall) heat shrink tubing is typically recommended instead.

PVC Heat Shrink Tubing 7mm–120mm — Reliable Insulation for Every Wire and Cable

Whether you're rewiring a vehicle, organizing a server rack, or finishing a DIY electronics project, loose or exposed wires are a constant frustration. Bare conductors invite shorts, abrasion damage, and failed inspections — and finding the right sleeve in the right color at the right size shouldn't be another obstacle. This PVC heat shrink tubing is designed for makers, electricians, hobbyists, and small-shop technicians who need a dependable, ready-to-use insulation solution across a wide range of cable sizes.

Each unit is sold as 1 meter (≈39.4") of tubing. Flat widths range from 7mm (Ø 4mm) up to 120mm (Ø 76mm / ≈3"), covering everything from thin signal wires to large battery cables and conduit bundles. The tubing is made from PVC with a 2:1 shrink ratio, activating at approximately 70–90°C (158–194°F). Available in multiple sizes and up to 12 colors — Black, White, Red, Blue, Green, Yellow, Transparent, Gray, Purple, Pink, Apple Green, and Orange Yellow.

Typical use cases include wire harness insulation and color-coding in automotive and marine wiring, cable bundling and strain relief in electronics assemblies, and protective sleeving for battery terminals, connectors, and solder joints in DIY and repair work. The transparent option is especially useful when you need to inspect connections after sealing.

ℹ️ Compatibility Note: This is a standard PVC heat shrink (2:1 ratio, non-adhesive). It is compatible with most copper and aluminum conductors, terminals, and connectors. For waterproof sealing, consider a dual-wall adhesive-lined heat shrink instead. Confirm the inner diameter (Ø) listed in the variant matches your cable's outer diameter before ordering.

✅ Key Features of These PVC Heat Shrink Tubing Sleeves

📏Wide Size Range — Flat widths from 7mm to 120mm (inner diameters Ø 4mm–76mm) cover thin signal wires through large battery cables and conduit bundles in a single product line.
🎨Up to 12 Color Options — Choose from Black, White, Red, Blue, Green, Yellow, Transparent, Gray, Purple, Pink, Apple Green, and Orange Yellow for intuitive wire color-coding and circuit identification.
🔥2:1 Shrink Ratio — Activates at approximately 70–90°C (158–194°F) with a standard heat gun; shrinks evenly around irregular shapes and connector bodies for a snug, professional finish.
🛡️Electrical Insulation — PVC construction provides dielectric insulation to help protect conductors from accidental contact, abrasion, and light moisture exposure in sheltered environments.
✂️Cut-to-Length Flexibility — Sold by the meter, so you can cut each piece to the exact length needed for terminals, solder joints, wire splices, or full cable runs without waste.
🔧Broad Application Fit — Suitable for automotive wiring, marine cable management, electronics repair, battery terminal protection, and general-purpose heat shrink tubing for DIY projects.

⚠️ Sizing Tip: Always measure your cable or connector's outer diameter before selecting a size. The inner diameter (Ø) shown in each variant should be at least 10–20% larger than your cable OD for easy installation. After shrinking, the recovered diameter will be approximately half the listed Ø value.

❓ Frequently Asked Questions

How do I choose the right flat width and diameter for my application?

Measure the outer diameter (OD) of the cable, wire, or connector you want to cover. The inner diameter (Ø) listed in each size variant should be at least 10–20% larger than your cable's OD so the tubing slides on easily before shrinking. For example, for a 6mm OD cable, the 9mm flat width (Ø 5mm) option is generally a close fit — confirm the recovered diameter (approximately Ø/2) will grip your cable adequately. When in doubt, size up.

Quick reference: 1 inch ≈ 25.4mm. So a 1" OD cable needs at least a 27mm flat width (Ø 16mm) option.

What is the shrink ratio, and how much will the tubing shrink?

This tubing is generally rated at a 2:1 shrink ratio. That means it will typically shrink to approximately half its original inner diameter when heat is applied. For example, the 12mm flat width (Ø 7mm) option will recover to approximately Ø 3.5mm. Actual recovery can vary slightly based on heat source, duration, and ambient temperature.

What temperature and tool do I need to shrink this tubing?

PVC heat shrink tubing typically activates at around 70–90°C (158–194°F). A standard heat gun on a low or medium setting works well. Move the heat gun steadily along the tubing to shrink evenly. Avoid open flames — they can scorch the PVC or cause uneven shrinking. A hair dryer generally does not produce enough heat for reliable shrinking.

Is this tubing waterproof or suitable for outdoor use?

PVC heat shrink tubing generally provides basic moisture resistance and is suitable for light indoor and sheltered outdoor applications. It is not designed for full waterproofing or submersion. For applications requiring a watertight seal — such as marine wiring below the waterline or outdoor junction boxes — an adhesive-lined (dual-wall) heat shrink tubing is typically recommended instead.

What wire gauges or cable sizes does each diameter fit?

Each variant lists the inner diameter (Ø) before shrinking. As a general guide:

7mm flat / Ø 4mm — fits cables up to approximately 3–3.5mm OD (e.g., thin signal wires, small terminals)
12mm flat / Ø 7mm — fits cables up to approximately 5–6mm OD (e.g., 14–16 AWG wire bundles)
23mm flat / Ø 14.5mm — fits cables up to approximately 12–13mm OD (e.g., multi-conductor cables)
50mm flat / Ø 32mm — fits cables up to approximately 28–30mm OD (e.g., large battery cables)
120mm flat / Ø 76mm — fits objects up to approximately 65–70mm OD (e.g., conduit bundles, large connectors)

Always measure your cable's OD and confirm before ordering.

Can I use this for color-coding wires and cable harnesses?

Yes — color-coding is one of the most common uses for this tubing. With up to 12 color options (Black, White, Red, Blue, Green, Yellow, Transparent, Gray, Purple, Pink, Apple Green, Orange Yellow), you can follow standard wiring color conventions or create your own identification system for complex harnesses. The Transparent option is particularly useful when you need to visually inspect a solder joint or connector after sealing.

How is this product sold — what length will I receive per order?

Each unit is 1 meter (≈39.4") of tubing. Select your flat width (diameter) and color from the variant options above, then choose the quantity you need. The tubing can be cut to any length with scissors or a utility knife before or after shrinking.
