Metal Lock Black

Description

ComStar announces  “no heat” solder for pipes and fittings of all types of metals, Metal Lock Black.  Metal Lock Black can be used on pipes and connections made of aluminum, black iron, steel, copper, brass and more, unthreaded or threaded. It’s easy to apply, fast to test pressure and permanent.  Metal Lock Black is strongly recommended when making repairs to refrigerators and air conditioning systems using hydrocarbon refrigerant.    Building on the success of ComStar’s Copper Lock, a no heat solder for copper/brass pipe & fittings, Metal Lock Black can be used on aluminum, black iron, steel, copper, brass and more, unthreaded or threaded pipes and fittings. It’s easy to apply, just sand the unthreaded areas to be joined, apply a small amount of Metal Lock Black to the fitting and pipe, insert and if possible, turn the pipe 180 degrees or more.  Then wait for 30 seconds before handling.  Depending on system operating pressures, tests can be conducted after two minutes.  For threaded fittings just apply Metal Lock Black as you would a normal thread sealant.

Metal Lock Black will set up a permanent leak proof bond in seconds.  It seals against most fluids, refrigerants, gases and chemicals and will withstand extreme vibration.  Metal Lock Black has a temperature range of –65 to +350 degrees F (-54 to 177 Celsius) and can withstand shear pressure up to 2,200 psi (ISO 10123).  It is non-toxic and meets several US military specifications.
