A tool (30) and a method for installing a seal (10) in a fitting (12) through which gas is flowing is disclosed. The tool (30) has a sleeve (32) with a first socket (34) that receives and holds the seal (10), and a second socket (36), adjacent to the first socket (34), that receives the fitting (12). A shaft (40) is axially movable within the sleeve (32) and has a contact surface (42) at one end engageable with the seal (10). The shaft (40) optionally has a conduit (56) with an inlet (58) in communication with the fitting (12) and an outlet (60) that vents to the atmosphere. In use, the seal (10) is loaded into the first socket (34), the second socket (36) is engaged with the fitting (12), and the shaft (40) is advanced to push the seal (10) from the first socket (34) into the fitting (12). Gas flowing through the fitting (12) is conducted to the atmosphere by the conduit (56), preventing gas pressure build-up behind the seal (10). |
