Hernon Pipe Sealant Approved for DEF Equipment Suppliers List

Hernon Manufacturing recently announced it was given approval for its Dripstop® 940 anaerobic pipe sealant from TerraCair, a manufacturer of diesel exhaust fluid (DEF) and urea. DEF is used with the catalytic converters for diesel engines made since 2010.

TerraCair publishes and distributes a DEF Equipment Suppliers list of approved companies that they have found to be contaminant-free and compliant with proper usage of DEF. Dripstop 940 was approved as a suitable pipe sealant for DEF technology and is now included on the list.

“As a result of a meeting with TerraCair representatives at the Petroleum Equipment Institute (PEI) show last month, Hernon Manufacturing was given the proper direction and contacts to pursue the listing,” said Bob Sollien, Northeast sales representative for Hernon Manufacturing.

The sealant also 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.
