Socket Fusion tooling includes a heater, heater adapters, depth gauge/chamfer tool, cold ring tool and a socket fitting holder for 2" and larger fittings. Socket heater adapters are available for 1/2" CTS – 4" IPS. Multiple socket heater adapters from 1/2" CTS – 1" IPS sizes can be fastened to the sides of the heater. This enables saddle fusion heater adapters to be fastened to the heater face independent from the socket adapters. 1–1/4" – 4" IPS socket heater adapters fasten to the heater faces.
