Actual Case History
PACCAR Approves Hernon Powerseal™ and Dripstop™ Sealants  after Success In Peterbilt Application
PACCAR has approved the use of Hernon sealants Powerseal™ and Dripstop™ after the successful implementation of these products at the Peterbilt division. PACCAR operates divisions such as Kenworth, Foden, DAF, and others. Peterbilt had previously utilized an anaerobic sealing compound during pre-assembly that did not offer the pliability necessary for part adjustment during final assembly.  Hernon's Powerseal™ 932 offered the essential pliability while still maintaining a consistent seal in an environment that includes exposure to hydraulic fluid and motor oil. Peterbilt chose Powerseal™ 932 and the Hernon Autosealer™ 2600 dispensing system to speed assembly and improve reliability of threaded assemblies.    
Hernon Powerseal™ is a single component, non-hardening pipe sealant that lubricates and seals threaded pipe connections and o-rings.  Powerseal™ is unaffected by water, oil, ammonia, glycerin, steam, exhaust fumes, and most hard-to-hold liquids.  Its pliable feature allows Powerseal™ to withstand severe vibration while not crumbling, cracking, or shrinking.  Powerseal™ is safe to use on all substrates including plastics and metals, unlike anaerobic sealants that causes stress cracking on many plastic threaded components.
To speed the assembly process and reduce sealant waste, Peterbilt is using the Autosealer™ 2600 sealant dispensing system.  The Autosealer™ 2600 is a low-cost, portable, and easy-to-use system for dispensing paste sealants directly onto threaded components.
Hernon Dripstop™ is a series of anaerobic sealants designed for plumbing, refrigeration, and hydraulics. Dripstop™ products are engineered with many advantages over conventional pipe dopes including hardening without shrinkage, lower cost, and no contamination. 
PACCAR's Six Sigma Program, a synergistic combination of strategic planning, leadership, and total quality management, pursued this solution.
