Wellhead Grease Fittings, Pressure Relief Tools & Plugs Series
Parker PGI's Pressure Relief Tools and Plugs were developed to properly connect to installed fittings to allow body cavity pressure to be vented to the atmosphere.
Parker PGI's Pressure Relief Tools and Plugs are offered in three styles to fit a variety of applications. These Pressure Relief Tools properly connect to fittings to allow body cavity pressure to be vented to atmosphere.
The standard Pressure Relief Tool PR11S8 connects to 1”-14 UNS thread sized Body Grease capped fittings and Giant Button Head capped fittings and has a 1/2” female NPT vent port to bleed to atmosphere. This PR tool has no pressure rating.
