Chronology :

In June 2021, UFPI learned of an investigation involving the performance of propane regulators produced by Winntec and installed in the appliances of certain Recreational Vehicle (RV) manufacturers. At that time, at least one RV manufacturer had alleged that the propane regulator led to multiple thermal events in its vehicles.

UFPI began to monitor the investigation and participated in meetings with representatives of the RV manufacturers and Winntec over the summer of 2021. A June 15, 2021, report indicated that the seat disc material used in the Winntec regulator was different from the material used in a competitor regulator.

Winntec later confirmed that in May 2018, it changed the material used in the seat disc of the regulator from nitrile rubber to fluoropolymer.

UFPI is aware that assessments made in the underlying technical evaluation have concluded that this change in materials can impact the integrity of the regulator’s second stage seal. UFPI also understands that Winntec has raised concerns around whether the installation practices of certain RV manufacturers may have caused these thermal events and that not all RV manufacturers that use the Winntec regulator have experienced field events.

To the best of UFPI’s knowledge and based on the technical information gathered to date, all field events have occurred in vehicles with Winntec regulators produced after the May 2018 materials change.

In early September 2021, UFPI learned that the fabricating manufacturer of the regulators submitted a Part 573 Report to NHTSA on or about August 25, 2021, for regulators installed as original motor vehicle equipment. While UFPI is not aware of any thermal events potentially related to Winntec regulators that UFPI sold into the aftermarket, it decided to conduct a recall to address those units in the field on September 7, 2021.

UFPI has provided Winntec with a list of its customers that have purchased the regulators for installation in new motor vehicles.
