Highside Leak Lock Thread Sealant - HS10001

Restore a dependable seal on refrigeration service connections with this universal/spec-match Highside Leak Lock Thread Sealant - HS10001. This thread and gasket sealant helps seal threaded fittings, flares, O-rings, and gasketed joints used in refrigeration and HVAC service work.

HS10001 is Highside Leak Lock, a universal/spec-match service sealant used when technicians need a non-hardening compound for refrigeration-style connections rather than ordinary pipe dope. It is commonly applied to threaded joints, flare surfaces, O-rings, and gasketed connections during assembly and reassembly.

Compatibility: HVAC and refrigeration service connections, threaded joints, flares, O-rings, and gasketed sealing surfaces that call for this type of service sealant.

Please confirm the fitting type, thread compatibility, sealant type, and intended service application before ordering.

Is it time to replace?

• Common Symptoms: Slow refrigerant or gas seepage at a service connection, a joint that will not seal cleanly after reassembly, or repeat callbacks from connection leaks.
• Visible/Sensory Cues: Old sealant residue on flare faces or threads, dried compound, oily leakage at a connection, or gasket surfaces that no longer seal smoothly.

Pro Tip: Use only a thin film on the sealing area and keep the inside of the line clean so excess compound does not contaminate the system.
