Hercules Brush-on Block 15703 Thread and Gasket Sealant, 4 oz, Can, Liquid, Paste, Blue Blue

Hercules® Brush-on Block™ is an all purpose, high performance pipe joint and gasket sealing compound for use on metals including aluminum, black iron, brass, copper, stainless steel, galvanized steel and plastics, including PVC and CPVC. Block sets up quickly and dries to form a very tough, yet flexible seal which will not harden, crack, crumble or shrink. It provides leakproof resistance to high pressure, temperature, expansion, contraction and extreme vibration. Joints can be disassembled easily, without damage to pipe or equipment. Block™ can be removed from skin or clothing, tools or equipment with isopropyl alcohol. Block™ is applied easily with the natural bristle brush even at temperatures as low as 20 deg F and performs over a temperature range of -90 to 450 deg F. It provides leakproof hydraulic resistance to 12,000 psi and withstands gas pressure to 2600 psi.
