Supco HS10001 1.3 Oz Leak Lock

The Supco HS10001 Leak Lock is an essential high-strength pipe joint sealant designed for the rigorous demands of HVACR and industrial plumbing. This resin-based soft-setting brushable paste remains permanently flexible, ensuring a reliable seal on both metal and plastic piping, including PVC, ABS, copper, and stainless steel. Engineered to withstand high-vibration environments, it prevents fittings from loosening over time while maintaining an airtight bond. It is rated for extreme conditions, performing reliably from -200°F to 400°F and managing pressures from a full vacuum up to 10,000 PSI. As a non-toxic joint sealing compound, it is chemically resistant to all refrigerants (CFCs, HFCs, and HCFCs), petroleum products, natural gas, and steam. This 1.3 oz tube of Leak Lock blue is a staple for technicians needing a permanent thread sealant that sticks to all clean surfaces and never becomes brittle, making it ideal for refrigeration fittings and manifold repairs.

• Universal Compatibility: Works effectively on all metal and plastic surfaces, including aluminum, brass, and rigid plastics.
• Extreme Pressure Rating: Safely handles systems ranging from full vacuum to 10,000 PSI, making it suitable for high-pressure refrigeration lines.
• Chemical Resistance: Impervious to oils, fuels, water, steam, and all common HVAC refrigerants like R-410A and R-22.
• Vibration Resistant: The flexible 1.3 oz tube formula prevents nuts and bolts from backing off due to mechanical movement.
• Indefinite Shelf Life: When properly sealed, the compound remains ready for use without drying out in the tube.
