Abstract: A safety wire plier includes a pair of plier arms with each of the arms including a jaw end and a handle. The plier arms of the safety wire plier are pivotally connected to each other for movement in either an open or closed position. The safety wire plier also includes a sealed lock for releasably locking the safety wire plier in the closed position.

Abstract: A pliers for manipulating hose clamps or spring clamps can include channels for engaging the ears of a clamp. In summary, a pliers can include a first lever including a first jaw and a first handle, a second lever including a second jaw and a second handle, where the first jaw includes a first clamping surface including a plurality of channels and at least two channels in the first clamping surface are not parallel to one another, and where the second jaw includes a second clamping surface including a mirror-image plurality of channels that complement the channels on the first clamping surface.

Abstract: A method for introducing additives into a closed system though a high pressure side service port is disclosed. In a first example, a method of introducing an additive into a closed system is disclosed comprising the steps of connecting a fluid flow path with the high pressure side service port of a closed system and transporting the additive from a fluid reservoir through the fluid flow path into the high pressure side service port of the system. The method may further comprise purging the closed system prior to introducing the additive into the system.
