All Categories

Packing Injection Fittings

The Packing Injection Fittings (Floating Ball-Taper Cavity) are high-pressure components designed with a specialized taper cavity configuration for industrial sealant injection applications. They feature a built-in safety vent hole, a 7/8″ wrench hex body, and a 3/4″ wrench hex stinger to ensure stable, controlled torque during installation. The internal design incorporates a floating ball mechanism secured at the base by a cross pin to reliably check flow within the process system.
