Most customers will never experience an issue with their Apollo valves. The few reports we do
receive related to body joint, stem packing or seat leaks involve solder valves rather than NPT, so
heat definitely plays a role. Limiting the amount of heat applied beyond the solder cup will prevent
most problems.
1. Always identify the alloy to be soldered. 77FLF EZ-Solder
contain silicon alloy, meaning heat transfer rates are identical to standard brass. Therefore

Note also that brass conducts heat at a rate 50% faster than bronze, so brass valves in general
require less heat input than comparable bronze valves.
2. Always review the applicable Apollo Installation, Operation & Maintenance Instructions to
ensure factory recommendations are being followed:

3. We also recommend viewing our Apollo soldering video and the Copper Development
Association-produced video entitled Soldering of No Lead...Valves. Both cover Industry
Best Practices relative to soldering valves. We particularly endorse heating of the tube prior
to heating the solder cup of the valve to reduce the total amount of heat applied to the valve.

4. The installer should be mindful of the type of gas being used. Acetylene is the hottest industrial
gas, meaning it requires the most care and caution when soldering vs MAPP gas or propane.
Always move the flame to evenly distribute the heat to all surfaces of the solder cup during
heating.
5. Do NOT oversize the torch tip! The torch tip selection should be appropriate for the pipe size,
based on the torch manufacturers' recommendation (see example below). In fact TurboTorch
technicians advise their tip sizing chart is based on wrot copper fittings, and they recommend
reducing the tip selection by 1 – 2 sizes when soldering (ball) valves due to the PTFE
components.
