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.
a. If no leaks are observed, no further action required.
b. 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. 2. If the service valve is closed with propane in the propane tank, apply a leak detection solution at the valve outlet connection:
a. If no leaks are observed, no further action required.
b. 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.

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

ECI2022-001 ECI2022-001 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. Go/No Go gauge Finger Tight No Visible Groove = Good Part Go/No Go gauge Finger Tight = Needs Replacement Figure 2: Go/No Go Gauge POL Nut – Groove Cut Through Roll Stamp Information ECI2022-001 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. POL connector POL threads

901C Service Valves Part No. : 901C3, 901C5 Size : NR Function : NR
Descriptive Information : The potentially impacted equipment are the Female POL threads on a limited number of RegO model 901C3 and model 901C5 service valves, which are used on Manchester Tank branded propane tanks installed in RVs, food and catering trucks, and a small number of other vehicles. 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. 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 re-installed. 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.

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 re- installed. 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. The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 22E-058 Page 3 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. Description of Remedy :
Description of Remedy Program : A Field Safety Advisory warning about the thread depth issue and advising
how to remedy the issue was sent to Manchester Tank, the only customer who received the affected valves. Manchester Tank is distributing the field safety advisory to its customers. Reimbursement and other issues with regard to the ultimate end consumer will be handled by other entities, including the RV manufacturers and/or their sales/service centers. ECI’s expectation is that they’ll handle reimbursement pursuant to their contracts and warranties with the ultimate end consumer. How Remedy Component Differs from Recalled Component :
Identify How/When Recall Condition was Corrected in Production : The threading of the recalled Valve was incorrect. The remedy or replacement Valve has the correct thread depth.
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 in December 2021. After analyzing units produced after December 2021, ECI has determined that the tool was correctly re-installed. ECI has no reason to believe that the units produced 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. Recall Schedule :
Description of Recall Schedule : Manchester Tank was notified on June 28, 2022 of the recall. ECI sent a
field safety advisory, notifying the company of the recall and describing how to remedy the issue. It is ECI’s understanding that Manchester Tank notified all of its customers. Notification of dealers and owners is not within ECI’s control.
