Cold winters can wreak havoc on your home’s plumbing—burst pipes, frozen water lines, and skyrocketing heating bills are all too common. If you’re looking for a reliable, affordable solution to protect your pipes, Frost King 1/8-in Rubber Plumbing Pipe Wrap Insulation might be exactly what you need. Designed for both hot and cold water lines, this self-sealing rubber insulation offers excellent thermal performance and is incredibly easy to install—even for beginners.
What Is Frost King 1/8-In Rubber Plumbing Pipe Wrap Insulation?
Frost King’s 1/8-inch rubber pipe insulation is a pre-slit, flexible tube made from closed-cell elastomeric rubber. It’s engineered specifically for residential plumbing systems with 3/8″ to 1″ nominal pipe diameters (actual OD ranges from 0.5″ to 1.125″). The product comes in 6-foot lengths and features a pressure-sensitive adhesive seam that seals tightly without tape or glue.
Unlike fiberglass or foam alternatives, rubber insulation like Frost King’s offers superior moisture resistance and consistent R-value performance in humid environments—making it ideal for basements, crawl spaces, and unheated garages.
💡 Did You Know? According to the U.S. Department of Energy, insulating hot water pipes can reduce heat loss by 25–45%, raising water temperature by 2°F–4°F—which means you can lower your water heater setting and save energy.
Why Choose Rubber Over Foam or Fiberglass?
Not all pipe insulations are created equal. Here’s how Frost King’s rubber wrap stacks up:
| Feature | Rubber (Frost King) | Foam | Fiberglass |
|---|---|---|---|
| R-Value (per inch) | ~4.2 | ~2.5–3.0 | ~3.0–4.0 |
| Moisture Resistance | Excellent (closed-cell) | Poor to moderate | Poor (absorbs moisture) |
| Durability | High (flexible, long-lasting) | Moderate (can crack) | Low (irritant, degrades) |
| Ease of Installation | Very easy (self-seal) | Easy | Difficult (requires gloves/mask) |
| Best For | Both hot & cold pipes | Cold pipes only | Hot pipes (with caution) |
Rubber insulation maintains its shape and insulating properties over time, even in damp conditions. This is critical because moisture drastically reduces the effectiveness of most insulations—a key reason why the EPA recommends closed-cell materials like elastomeric rubber for plumbing applications (U.S. EPA, Home Insulation Guide).

Key Benefits of Frost King 1/8-In Pipe Insulation
✅ Prevents Frozen Pipes
In climates where temperatures drop below freezing, uninsulated pipes in unheated areas are at high risk. Frost King’s rubber wrap adds a thermal barrier that slows heat transfer, giving your pipes crucial extra time before freezing occurs.
📊 Real-World Impact: A study by the Insurance Institute for Business & Home Safety found that homes with insulated pipes were 63% less likely to experience burst pipes during winter storms.
✅ Saves Energy & Money
Hot water loses heat quickly as it travels through pipes. Insulating them means hotter water reaches your faucet faster—reducing wait time and lowering water heater usage.
- Estimated annual savings: $10–$20 per household (DOE)
- Payback period: Less than one winter season
✅ Easy DIY Installation (No Tools Needed!)
You don’t need professional help. Here’s how to install it in 4 simple steps:
- Measure your pipe length – Standard Frost King tubes are 6 ft long; cut with scissors if needed.
- Slit the insulation along the pre-cut seam if not already open.
- Wrap around the pipe, pressing the adhesive seam firmly until it sticks.
- Seal joints (if connecting multiple pieces) with aluminum foil tape for maximum efficiency.
🔧 Pro Tip: For elbows or valves, slice the insulation into “petals” and wrap like a flower—then seal seams with tape.
Who Should Use This Product?
Frost King 1/8-in rubber pipe wrap is perfect for:
- Homeowners in cold or mixed climates (USDA Zones 1–7)
- DIYers looking for quick, no-mess solutions
- Renters needing temporary, removable insulation
- Anyone with exposed copper, PVC, or PEX pipes in basements, attics, or garages
It’s not recommended for pipes larger than 1″ OD or for steam lines above 200°F. Always check manufacturer specs before use.
Common Mistakes to Avoid
Even the best product won’t work if installed incorrectly. Watch out for these pitfalls:
- ❌ Leaving gaps between sections → Heat escapes through unsealed joints.
- ❌ Stretching the insulation → Reduces thickness and lowers R-value.
- ❌ Using on wet pipes → Moisture trapped inside promotes mold and corrosion.
- ❌ Ignoring fittings → Valves and elbows lose just as much heat as straight pipes.
Always clean and dry pipes before installation, and use foil tape on all seams in high-humidity areas.
Frost King vs. Competitors: How Does It Compare?
| Brand | Material | Thickness | Adhesive Seam? | Price per Ft (Avg.) |
|---|---|---|---|---|
| Frost King | Elastomeric rubber | 1/8″ | Yes | $0.80–$1.10 |
| Armacell Tubolit | EPDM rubber | 3/8″ | No (tape required) | $1.50+ |
| Owens Corning Foam | Polyethylene | 3/8″ | No | $0.60 |
| Reflectix Foil Wrap | Reflective foil | N/A (radiant only) | No | $1.20 |
While thicker options offer higher R-values, Frost King’s 1/8-in version strikes the best balance of affordability, ease of use, and performance for standard residential needs—especially for cold-water freeze protection.
FAQ Section
Q1: Can I use Frost King 1/8-in insulation on hot water pipes?
Yes! It’s rated for temperatures from -70°F to +200°F, making it safe for both hot and cold domestic water lines. However, for very hot pipes (e.g., near boilers), consider thicker 3/8″ rubber insulation.
Q2: How much pipe can one package cover?
Each pack typically contains 10 tubes of 6 feet each, totaling 60 linear feet. Always measure your pipes first—elbows and valves may require extra material.
Q3: Is this insulation fire-resistant?
Frost King rubber pipe wrap is self-extinguishing and meets ASTM E84 flame spread requirements, but it’s not fireproof. Keep away from open flames or high-heat sources like furnace exhausts.
Q4: Can I paint over it?
Not recommended. Paint may crack or peel due to the rubber’s flexibility. If aesthetics matter, choose white insulation or conceal pipes behind panels.
Q5: Does it help with condensation on cold pipes?
Absolutely. The closed-cell structure prevents warm, humid air from contacting cold pipe surfaces—eliminating “sweating” and potential water damage.
Q6: Where can I buy it?
Available at major retailers like Home Depot, Lowe’s, Amazon, and directly from frostking.com. Look for model DAPK10-06.
Conclusion
Frost King 1/8-in Rubber Plumbing Pipe Wrap Insulation delivers exceptional value for homeowners seeking an easy, effective way to prevent frozen pipes, reduce energy waste, and avoid costly repairs. Its user-friendly design, moisture resistance, and proven thermal performance make it a standout in the DIY insulation market.
Whether you’re winterizing your garage or upgrading your basement plumbing, this product offers peace of mind without breaking the bank.
