10 PCS. XFITTING 1 X 1 X 1/2 PEX TEE - PEX B PIPE, CRIMP FITTINGS, LEAD-FREE BRASS

works well

got to like new

Used them to tap into 3/4 poly gas line (which measures internally the same as 1 PEX)

The heater core has a plastic t fitting on it. Mine broke. The part is expensive from Dodge. But you can cut the hoses and put one of these t fittings on it and get back on the road. You need some hose clamps to secure it and refill your coolant, and youre back on the road! Will have an installation video on my Youtube channel

Works as advertised
