Rehvac Recalls Safety Relief Plugs for Nitrous Oxide and HVAC Tools

Rehvac Manufacturing is recalling safety relief plugs used in nitrous oxide systems and HVAC tools because they may fail to release pressure, posing a burst hazard.

What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: The recall involves a risk-of-harm product (cylinder burst) where injury has not yet been reported, which aligns with the 'High' severity criteria in the rubric.

Plain-English summary

Rehvac Manufacturing Co. of San Antonio, Texas, is recalling approximately 4,700 safety relief plugs used in nitrous oxide systems and heating, air conditioning, and refrigeration (HVAC) pressure testing tools. The recalled plugs are nickel-plated and have the number "3000" stamped on the face. These plugs are designed to release pressure but may fail to do so, allowing pressure to build up in the cylinder.

The hazard exists because if a cylinder containing these plugs is overfilled and overheated, it can burst, posing an injury hazard to consumers. The company has received one report of a cylinder that was overheated, overfilled, and burst, but no injuries have been reported. The plugs were sold nationwide through HVAC and nitrous oxide systems suppliers and retailers from August 2006 through June 2007 for about $5 each.

Consumers should immediately stop using cylinders that contain the recalled plugs and place them in a cool location. They should contact Rehvac at (800) 856-5668 between 9 a.m. and 6 p.m. ET Monday through Friday, or visit www.oemregs.com, to obtain a free replacement plug.
