Works great for LS swaps to bypass your heater coreFits 4.8,5.3,6.0,L92

Nice

Work really good when you got to do a heater core bypass, you wont have your heater anynore but your radiator fluid will quite leaking if the heater core caused it to leakThis makes sure it wont pinch the hoses also when you do it

Works perfect to bypass the heater lines in my LS swap. Exactly as described.

Fit perfectly on a LS2 GTO.Garbage factory heater bypass valve broke so I tried to cobble together a loop from the parts store to bypass the whole heater loop temporarily. The loop I cobbled together fit poorly as it had to be so big due to having a size adapter coupler in the middle.This loop dropped right in, eliminated the extra fitting I needed before and is nice and snug to the water pump. Zero leaks and just reused the factory hose clamps.
