Plug Compatibility: Hot and cold water serviceTemperature range: -40 F to 275 F (-40 C to 135 C) The Watts TP Series are to be permanently installed in the line at required test locations. The cap protects the valve and provides an additional seal. Once the cap has been removed, either a test thermometer or gauge adapter with the proper pressure gauge can be inserted through the self-closing valve. Readings, adjustments or tests can be accomplished. When the probes are with-drawn the valve seals. The protective cap is then replaced.Tests should be made as quickly as possible since the reseal time is dependent upon time of insertion, temperature and pressure. Slower valve reseal can be expected at lower temperature and lower pressures.
