My experience has been mixed. I have an OEM spring clamp against the block, but a traditional unlined worm drive hose clamp on the pipe end. The pipe end leaked as it's kinda twisted a bit due to the metal pipe being slightly misaligned and some lateral distorting forces, where the block end is simply straight. No evidence of leaking at the block end as I've now twice disconnected it with the head fun and games and can look directly down upon it.
