AirRepair® Sealant is a revolutionary leak repair system for pressurized telephone cables and splices.  AirRepair® Sealant seals air leaks in lead-sheathed cables and splice enclosures, polyethylene “Stalpeth®” cable jackets, load coils, end-plates, and more.  AirRepair® Sealant eliminates messy and dangerous molten lead “hot wipe” procedures.  AirRepair® Sealant allows a single craftsperson, with minimal training, to effectively and economically seal 20 or more leaks per day.

AirRepair® Sealant is a 2-part, fast-curing, gray paste.  The AirRepair® Sealant 2-part paste is packed in an easy-to-use system.  Pre-measured packaging contains enough material to seal one typical leak, approximately 6 square inches at a coating thickness of 1/4 inch.

AirRepair® Sealant is a no-sag paste that, once mixed, can be immediately applied to the cable or splice underside, along seams, and in the “crotch” area. The sealant will hold air pressure within 10 minutes of mixing and application. The sealant cures at ambient temperatures as low as 40°F, forming a tough seal.  The cured seal is resistant to water, salt, oils, and other manhole contaminants.
