UL\u00ae performs various tests to determine the suitability of pipe sealants for a particular use.\u00a0 The UL\u00ae classification does not state the strength of the product or the maximum sealing pressure for other uses.<\/p>\n

For example, Permabond LH050<\/i> is classified by Underwriters Laboratories Inc.\u00ae for use in devices handling gasoline, petroleum oils, and natural gas (pressure not over 300 psig) not exceeding 2 in. pipe size; propane and butane not exceeding 1 in. pipe size. <\/i><\/p>\n

and<\/i><\/p>\n

Permabond LH050 is classified by Underwriters Laboratories Inc.\u00ae for use in sprinkler system and water spray system piping not exceeding 2 in. pipe size containing air, nitrogen, water, propylene glycol or glycerol antifreeze solutions.<\/i><\/p>\n

For clarification, in the first statement, the 300 psig limitation is only for natural gas as tested by UL\u00ae.\u00a0 UL\u00ae tested LH050 to 450 psig on natural gas to provide the classification of 300 psig.\u00a0 UL\u00ae does not test the pipe sealant to failure but stops at 450 psig.<\/p>\n

Similarly, Permabond LH150 i<\/i>s classified by Underwriters Laboratories Inc. \u00ae for use in devices handling gasoline, petroleum oils, and natural gas (pressure not over 100 psig) propane and butane not exceeding 2 in.<\/i><\/p>\n

Again the 100 psig refers only to the natural gas, and that value is granted based on testing with propane or butane.<\/p>\n

What is the strength of Permabond Pipe Sealants?<\/h2>\n

In most cases, we\u2019ve determined that there is an instant seal of up to 1000 psi and after full cure, the pipe sealant will, in general, exceed the burst rating of the pipe.<\/p>\n

How do anaerobic pipe sealants work?<\/p>\n

Like all anaerobic adhesive sealants, it takes two things to cause cure \u2013 eliminate oxygen + provide metal ions.\u00a0 So when confined from oxygen between the metal threads cure occurs.\u00a0 They form a seal which is inert to water, steam, hydrocarbons, most acids, solvents, and glycol-based products.<\/p>\n

In addition to products with UL\u00ae Classification for specific needs, pipe sealants are available with WRAS, DVGW, and NSF\/ANSI 61 certification for potable water.\u00a0 There are also hydraulics grades which are unfilled resins that contain no particles which might clog or foul hydraulic screens and valves.<\/p>\n
