New literature describes this company’s LH-050 pipe sealant and HL-126 weld sealant for fire-protection systems. Both products eliminate repair costs by preventing leaks. LH-050 pipe sealant provides an instant seal of over 600 psi and a cured, plastic seal of 10,000 psi. HL-126 weld sealant cures to a permanent plastic seal that fills imperfections in the welded surface. Both products are easy to use, and cure in response to the presence of metal and the absence of air.
