Dripstop 940 a DEF Compatible Thread Sealant
Oct. 22, 2012
-- Representatives from Hernon Manufacturing, the innovator in adhesives, sealants and dispensing equipment, recently attended the Petroleum Equipment Institute (PEI) 2012 Convention in Las Vegas. Attendees included original equipment manufacturers (OEMs), sellers and installers of equipment used in service stations, terminals, bulk plants, fuel oil and gasoline delivery and similar petroleum marketing operations.
Connecting with key industry personnel, Hernon’s Northeast Sales Representative, Bob Sollien, had this to say about the show, “The PEI Convention was an ideal place for us to meet end users – those who actually install diesel and DEF dispensing systems. We also made some good contacts with OEM’s who could influence the companies that purchase their equipment to use our DEF (diesel exhaust fluid) compatible thread sealant.”
Hernon Manufacturing has engineered a validated DEF compatible anaerobic pipe sealant called Dripstop® 940. This thread sealant recently received the necessary approvals and exhibited 100% passing results from Intertek, which conducts thousands of automotive fuel and lubricant analytical tests each month. This testing confirmed that Dripstop® 940 was containment free to ISO-22241 standards and therefore compatible for DEF technology.

Dripstop® 940 can be used in the manufacturing of petroleum dispensing parts and equipment and during the installation of diesel and DEF dispensing systems. Dripstop®
940 has superior sealing, and has been specially formulated to be used with stainless steel pipe fittings and mild locking performance compared to tapes and non-hardening dopes. Dripstop® 940 reduces costs by eliminating leakage and increasing the assembly line speed.
For use on inactive metals such as stainless steel and monel, Dripstop® 940 is a high-speed thread sealant used in chemical process piping. 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 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.
"Dripstop® 940 provides an instant seal against liquid and gas leaks at moderate pressures. For maximum pressures, the product should be allowed a full cure of 24 hours. It also eliminates waste in that there is no dripping or running," said Sollien. "Additionally, because it is solvent free, it won't crack or shrink due to solvent evaporation."
Typical applications for Dripstop® 940 are: DEF bulk transfer stainless steel pipe fittings, fuel line fittings, plated flare fittings, pulp and paper mills, refinery piping, instrumentation fittings, waste treatment plants, textile equipment, piping for chlorine and caustic sodas, hydraulic line fittings, pneumatic line fittings, fluid connections, steam lines up to 250 psig and pipe plugs.
“We are now following up with the end users we met at PEI and those OEM’s who could influence the use or our product as an approved source,” added Sollien. “There is still uncertainty in the industry as to what sealant should be used for the application of DEF systems, so we are in the process of educating the industry about our DEF compatible product.”
