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.

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.
