What is wrong with this picture (connection problem)?

The hose is 1/2 NPT male "swivel", which is a straight mechanical thread rather than a tapered thread.

NPT swivel fittings are like JIC fittings in that the connecting surfaces are male and female flares.

You need an adapter or hoses with i/2 NPT male without the swivel modifier.

Alright! Thanks to everyone for the help. I will be heading to Rural king Tomorrow for the exchange!

THanks again!

Also, 1/2" lines are WAY overkill for your grapple. Save some money and real estate and get 3/8" or even 1/4" lines. The grapple cylinder is small and requires very little flow. Smaller lines will also help slow the grapple down a little providing better usability.

Yes, I agree. the reason I ended up with 1/2" was because that was the only diameter that was available in the length that I needed.

However, I returned the whole lot. What I found was that one of the QD couplers was loose the other was tight. So they did not have the same threads even though the package indicated the same threads.

I then purchased a set of lines (3/8), 3/8 to 1/2 adaptors and a new QD units. ALL of the connection are tight after a few turns.

THanks again for all the help!.
