Not sure it can be done but you probably need to install an inner metal connector also. https://www.zoro.com/powergrip-sb-s...MI_Pfd7vfE3gIVyYCfCh38HQeWEAQYAiABEgJnRvD_BwE

The inner sleeve really needs to be a hose barb, not smooth. You're probably gonna spend more on a barb & clamp than just getting the right length hose. Jack E/NJ
Simple, just don't put any coolant in it. Push it off the trailer, into the parking spot at the car show.
Those are good for one time use, then good luck getting one off without cutting the hose underneath. Had to change out a waterpump that had those on the hoses, wanted to keep the hoses as they were good. Ended up slicing into the hose a bit, luckily there was enough left past the barb to seal up.
