Parker Hannifin PT1 Cork Insulation Tape

The Parker Hannifin PT1 Cork Insulation Tape is a professional-grade asphalt-impregnated cork wrap engineered for high-demand HVAC and refrigeration environments. This 1/8" x 2" x 30' insulation roll provides an immediate thermal barrier to stop cold pipe sweating and eliminate condensate dripping, which prevents moisture damage to surrounding woodwork and mechanical components. Specifically formulated for suction line insulation and cold water piping, the PT1 maintains thermal stability for hot pipes up to 158°F (70°C). The aggressive adhesive backing ensures a permanent bond to any dry metal surface, effectively sealing out ambient air and preventing the corrosive effects of localized condensation. This non-hardening pipe wrap is highly flexible, allowing technicians to achieve a tight, gap-free seal around complex fittings, valves, and elbows without the need for additional fasteners or adhesives.

Key Benefits for Contractors

• Eliminates Condensation: High-density cork insulation content prevents pipe sweating and moisture accumulation in high-humidity environments.
• Superior Adhesion: Industrial-strength pressure-sensitive adhesive bonds to copper, iron, and steel piping even under temperature fluctuations.
• Thermal Efficiency: Effective for heat loss reduction on hot water lines and maintaining superheat on refrigeration suction lines.
• Easy Application: Flexible asphaltic composition allows for neat wrapping around irregular shapes and tight offsets without cracking.
• System Protection: Seals out moisture to protect against pipe corrosion and prevents water damage to building interiors.

Common Questions

Can Parker PT1 be used on outdoor refrigeration lines?
While the asphalt cork tape is moisture-resistant, for outdoor service, it should be protected from direct UV exposure with a weather-resistant coating or jacket to prevent the asphaltic binder from degrading over time.

Does this tape require additional mastics or adhesives for a seal?
No, the PT1 cork tape features a high-tack adhesive backing. Ensure the pipe surface is clean and dry before application to achieve a permanent, airtight bond.

What is the maximum operating temperature for this cork wrap?
The Parker Hannifin PT1 is rated for intermittent temperatures up to 158°F, making it suitable for standard domestic hot water and low-pressure steam return lines.
