Propane Leak May Cause Fire

A propane leak in the presence of an ignition source can increase the risk of a fire.

 

NHTSA Campaign Number: 22E058

Manufacturer Engineered Controls International, LLC

Components EQUIPMENT

Potential Number of Units Affected 9,500

 

Summary

Engineered Controls International, LLC (ECI) is recalling certain RegO propane service valves, part numbers 901C3 and 901C5. Due to incorrect thread depth, the service valves on the LPG tanks may not connect properly, which can cause a propane leak.

 

Remedy

ECI is working with the propane tank supplier, Manchester Tank, to provide replacement valves free of charge. Affected recreational vehicle manufacturers will be managing the recall repairs. Owners may contact their respective recreational vehicle manufacturer’s customer service numbers.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.

 


Inspection Procedure for Vehicles in Service with Propane in the Propane Tank

RegO Model 901C Service Valves

07/12/2022

 

What Should Be Done? Contact a professional to locate the service valve on the container to inspect the model number and date code to determine whether the valve is in scope (reference “Field Safety Advisory – RegO Model 901C Service Valves”).  If the date code does not fall within the specified range, no further action is required.  If the date code falls within the specified range, then follow the instructions below.

 

WARNING:  FAILURE TO FOLLOW THESE STEPS AND REMOVE FROM SERVICE ANY CONTAINER THAT CONTAINS A LEAKING SERVICE VALVE COULD RESULT IN A FIRE OR EXPLOSION AND SERIOUS PERSONAL INJURY, PROPERTY DAMAGE, OR BOTH.

 

WARNING:  IF YOU ARE NOT A PROPERLY TRAINED LP-GAS PROFESSIONAL, DO NOT ATTEMPT ANY OF THE STEPS OUTLINED BELOW, OR TO OTHERWISE INSPECT, TEST OR ALTER THE SERVICE VALVE ASSEMBLY.  ATTEMPTING TO DO SO WITHOUT THE PROPER TRAINING COULD RESULT IN A FIRE OR EXPLOSION, AND SERIOUS PERSONAL INJURY, PROPERTY DAMAGE, OR BOTH.

 

  1. If the service valve is open (and the entire propane system is pressurized), apply a leak detection solution at the valve outlet connection.
    1. If no leaks are observed, no further action required.
    2. If a leak is observed at this valve outlet connection and tightening the connection does not stop the leak, close the service valve and contact your OEM, distributor, or dealer for further guidance.

 

  1. If the service valve is closed with propane in the propane tank, apply a leak detection solution at the valve outlet connection:
    1. If no leaks are observed, no further action required.
    2. If a leak is observed at this valve outlet connection and tightening the connection does not stop the leak, close the service valve and contact your OEM, distributor, or dealer for further guidance.

 

Should you have any questions, please contact your OEM supplier, distributor or dealer.

 

Sincerely,

Field Safety Advisory

RegO Model 901C Service Valves

06/27/2022

 

RegO has become aware of a potential issue with the female POL threads on a limited number of RegO model 901C3 and model 901C5 service valves.  In some instances, the thread depth of the POL outlet is less than specification, which could result in a leak of propane. Potentially affected valves would have been installed in a limited number of Manchester Tank branded RV tanks dated 2021 and 2022.  THIS COULD RESULT IN A FIRE OR EXPLOSION AND SERIOUS PERSONAL INJURY, PROPERTY DAMAGE, OR BOTH.

 

Which Valves May Be Affected?  The affected valves have manufacturing date codes between 02X21 and 02X22.  The ‘X’ represents any letter between A through E, which denotes the week of the month the valve was assembled.  The date code is marked on a wrench flat.  Below is a key to reading the date codes marked on the wrench flat of the valve and their locations. (See Figure 1.)

 

Figure 1: Model Number and Date Code Examples

 

What Should Be Done? Contact a professional to locate the service valve on the container to inspect the model number and date code to determine whether the valve is in scope.  If the date code does not fall within the specified range, no further action is required.  If the date code falls within the specified range, then follow the instructions below, depending on whether anything is installed in the outlet of the valve and whether there is container pressure.

WARNING:  FAILURE TO FOLLOW THESE STEPS AND REMOVE FROM SERVICE ANY CONTAINER THAT CONTAINS A LEAKING SERVICE VALVE COULD RESULT IN A FIRE OR EXPLOSION AND SERIOUS PERSONAL INJURY, PROPERTY DAMAGE, OR BOTH.

 

WARNING:  IF YOU ARE NOT A PROPERLY TRAINED LP-GAS PROFESSIONAL, DO NOT ATTEMPT ANY OF THE STEPS OUTLINED BELOW, OR TO OTHERWISE INSPECT, TEST OR ALTER THE SERVICE VALVE ASSEMBLY. ATTEMPTING TO DO SO WITHOUT THE PROPER TRAINING COULD RESULT IN A FIRE OR EXPLOSION, AND SERIOUS PERSONAL INJURY, PROPERTY DAMAGE, OR BOTH. 

 

  1. If nothing is installed in the outlet of the valve:

a. Use the supplied go/no-go gauge POL nut to determine if the threads are the proper depth. (See Figure 2.) If the threads are not the proper depth, securely close the valve, remove the container from service, and replace the valve. Do not use the container without first replacing the valve.

b. Alternatively, close the service valve and attach a POL connector to the service valve outlet with an air fitting installed on the ¼” NPT threads. (See Figure 3.)

i. Apply 50-100 psi air pressure back towards the outlet of the valve;

ii. Use a leak detection solution to determine if this connection is leak tight;

iii. If the connection is not leak-tight, securely close the valve, remove the container from service, and contact your OEM, distributor, or dealer for further guidance. Do not use the container without first replacing the valve.

 

  1. If a POL connector is installed in the outlet of the valve and there is no container pressure:

a. Remove the POL connector from the outlet of the service valve and use the supplied go/no-go gauge POL nut to determine if the service valve threads are the proper depth. (See Figure 2).

i. If the threads are the proper depth, no further action is required.

ii. If the threads are not the proper depth, securely close the valve, remove the container from service, and contact your OEM, distributor, or dealer for further guidance.

 

b. Alternatively, close the service valve and attach a POL connector to the service valve outlet with an air fitting installed on the ¼” NPT threads. (See Figure 3)

i. Apply 50-100 psi air pressure back towards the outlet of the valve;

ii. Use a leak detection solution to determine if this connection is leak tight;

iii. If the connection is not leak-tight, securely close the valve, remove the container from service, and contact your OEM, distributor, or dealer for further guidance.

 

  1. If a POL connector is installed in the outlet of the valve and there is propane pressure in the container:

a. If the service valve is open (and the entire propane system is pressurized), use a leak detection solution at the valve outlet connection.

i. If no leaks are observed, no further action required.

ii. If a leak is observed at this valve outlet connection and tightening the connection does not stop the leak, close the service valve and contact your OEM, distributor, or dealer for further guidance.

 

b. If the service valve is closed:

i. Remove the POL connector from the outlet of the service valve and use the supplied go/no-go gauge POL nut to determine if the service valve threads are the proper depth. (See Figure 2 above.)

1. If the threads are the proper depth, no further action is required.

2. If the threads are not the proper depth, securely close the valve, remove the container from service, and contact your OEM, distributor, or dealer for further guidance.

 

ii. Alternatively, close the service valve and attach a POL connector to the service valve outlet with an air fitting installed on the ¼” NPT threads. (See Figure 3 above.)

1. Apply 50-100 psi air pressure back towards the outlet of the valve;

2. Use a leak detection solution to determine if this connection is leak tight;

3. If the connection is not leak-tight, securely close the valve, remove the container from service, and contact your OEM, distributor, or dealer for further guidance.

Chronology :

Evidence indicates that a tool change in February 2021 for a limited production run resulted in an incorrect thread depth for the affected valves. The tool was later de-installed and re-installed for the next production run in December 2021. There was no production run for this product between February 2021 and December 2021. After analyzing units produced after December 2021, ECI has determined that the tool was correctly reinstalled.

After learning of the issue, ECI tested all remaining units in stock and found no affected units.

Additionally, Manchester tested all of its remaining stock and, out of approximately 2,600 units, found 462 affected units. On June 28, 2022, ECI sent a field advisory to Manchester for its distribution to its customers.

The field advisory explains how to identify and test the service valves to determine whether they are affected by this issue. ECI has been informed that Manchester has circulated this field advisory to all of its customers.

ECI has further been informed that two of Manchester’s customers, Winnebago and Tiffin, conduct leak checks of propane tanks, including service valve assemblies, as part of their normal operating procedure. Winnebago received 2,400 potentially affected units and Tiffin received 2,151 potentially affected units, and to date, ECI has not been informed of any issues with those units.

ECI has no reason to believe that the units produced in or after December 2021 are affected by the incorrect thread depth issue. Nevertheless, out of an abundance of caution, ECI has included units produced through February 2022 within the recall.
