Mueller Industries PC-4 4" Pressing Chain with Case

The Mueller Industries Press System pressing chain comes with a durable case and is intended for use with the PC-280 press tool or the PC-100 press tool. The 4-inch pressing chain is installed around the fitting to be pressed. The press tool is used with the pressing chain and adapter jaw to create a leak-free connection. When properly crimped, a unique “N” witness mark is clearly visible.
