Watts LFTP Series allows you to take pressure or temperature
readings - quickly - and eliminate the need for leaving costly
gauges or temperature recorders on the line. Can be used on
various applications of gas, air, water or chemicals to 500psi
(34 bar). The LFTP features Lead Free* construction to comply
with Lead Free* installation requirements. Recommended maxi-
mum temperature ratings of Neoprene is 200°F (93°C), EPDM is
275°F (135°C) and Viton ® is 400°F (204°C).
The pressure gauge adapter has a .076 diameter probe of 300
series stainless steel with Lead Free* brass union nut. The probe
operates in either 1 ⁄
4
" or 1 ⁄
2
" NPT sizes to accommodate insu-
lated pipe applications.
Features
• Allows quick and efficient temperature or pressure readings.
• Eliminates leaving expensive gauges or temperature recorders
in line.
• Economical means of balancing heating and air conditioning
systems
• Eliminates shutting down system for temperature and pressure
checks
Specifications
Temperature or Pressure Checks
The Watts LFTP 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probes are withdrawn the valve seals.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 pres-
sure. Slower valve reseal can be expected at lower temperature
and lower pressures. Lead Free* Temperature or Pressure Test
Plugs shall be constructed using Lead Free* materials. Lead
Free* Test Plugs shall comply with state codes and standards,
where applicable, requiring reduced lead content.
