A Validated DEF Compatible Thread Sealant

In 2010, stricter EPA standards were set in place and enforcement began requiring all new diesel engines built, to switch over to DEF (diesel exhaust fluid) technology to help neutralize NOx emissions. Typically, in DEF bulk transport and transfer equipment, stainless steel fittings are used. Dripstop® 940 is specially formulated to work with stainless steel and now shows compatibility with DEF.

Hernon Manufacturing submitted samples of its Dripstop® 940, an anaerobic pipe sealant, to Intertek which conducts thousands of automotive fuel and lubricant analytical tests each month. The product received the necessary approvals and exhibited 100% passing results for the requirements stated in the ISO-22241.

Normally, inactive materials like stainless would require a primer to assure predictable cure. Dripstop® 940 is formulated to cure without the necessity of a primer, but, priming does reduce cure time. The enhanced chemistry of Dripstop® 940 delivers a super-fast cure speeds on conventional materials, like carbon steel, brass, etc. This pipe sealant withstands high pressures, sealing up to 250psig steam at 400°F (204°C) continuous service while maintaining its chemical inertness. It also lubricates threads during assembly, prevents galling, and assures smooth disassembly.
