4.6 Pressure Connection
All forged meters bodies sizes 3” (DN80) to 12” (DN300) are supplied with
½” NPT Pr adapters and ½” NPT blind plugs. Adapters and plugs are sealed
with PTFE tape and hydrotested with the meter body. After the hydrotest,
adapters and plugs are painted together with the meter body. Where
necessary, seals on Pm (Pr) point adapter (at both ends) and the blind plug
should be replaced with appropriate sealant for the application. Hold the Pr
point adapter with a 30mm wrench while removing the blind plug or fitting
new connections.
