Leak Lock is a state-of-the-art high strength, pipe joint sealant consisting of chemically resistant film formers, plasticers, reinforcing fillers and solvents .
- A resin based brushable paste which remains permanently flexible, adheres to internal surfaces and fills voids
- Ideal for metal and plastic materials subject to extreme vibrations
- Effective in temperatures from -200ƒF (-93ƒC) to 400ƒF (204ƒC), full vacuums and pressures to 10,000 PSI
Leak Lock can be used on all metal or plastic materials, including but not limited to, aluminum, aluminum alloys, cast irons, copper, copper alloys, (brass, bronze, etc...), magnesium and magnesium alloys, carbon steels, stainless steels, galvanized surfaces, PVC, CPVC, ABS, fiberglass, black polypropylene, and kynar. Leak Lock should be applied to threaded joints, flanged joints, gasket surfaces and all mating surfaces where a fluid-tight seal is required.
Leak Lock seals a broad range of chemicals including all refrigerants such as R-12, R-22, R-502, R-134A, etc., all CFC, HFC and HCFC refrigerants, petroleum products, natural and manufactured gases, steam, water, air, etc. No other sealant offers the application range of Leak Lock. Use alcohol as a cleansing solvent prior to setting.
Available in 1 1/3 oz. tube; 4 oz. & 16 oz. brush top plastic jars; 1 gal. can
What is Leak Lock?
Leak Lock is a
state-of-the-art high strength, pipe joint sealant consisting of chemically
resistant film formers, plasticers, reinforcing fillers and solvents .
How It Works
When Leak Lock is applied to pipe joints, it adheres to the mating surfaces.
After joints are assembled, Leak Lock sets to form a chemically resistant
flexible fluid-tight seal.
How to Use It
Leak Lock should be applied to clean joint surfaces, either with the applicator
brush or any convenient spatula. Apply Leak Lock to both mating surfaces.
Tack should be allowed to develop before joints are assembled.
Where to Use It
Leak Lock can be used on all metal or plastic materials, including but
not limited to, aluminum, aluminum alloys, cast irons, copper, copper
alloys, (brass, bronze, etc ...), magnesium and magnesium alloys, carbon
steels, stainless steels, galvanized surfaces, PVC, CPVC, ABS, fiberglass,
black polypropylene, and kynar. Leak Lock should be applied to threaded
joints, flanged joints, gasket surfaces and all mating surfaces where
a fluid-tight seal is required. Special Applications - Leak Lock is ideal
for joining dissimilar metals and materials. Prevents loosening of nuts,
bolts, plugs and fittings. Call Highside for specific applications and

Leak Lock is not recommended for use with alcohols.
CURE TIME: Leak lock will cure and be ready for service in as little
as 20 minutes or no more than 24 hours depending on pipe size and temperature
Actual set times are dependent on pipe size and ambient temperature, but generally are as follows: 0 to 1/2" = 1 to 2 hours; 1/2" to 1 1/2" = 4 to 6 hours; 2" to 4" = overnight. Use alcohol as a cleaning cleansing solvent prior to setting and for clean-up.
