1-1/2" x 2" Hose Reducing Barb?

I need to get from 1-1/2" head discharge hose to a 2" seacock. The existing arrangement consists of one hose shoved inside another and all slathered up with 5200. I've been looking around but can't seem to find a source, any thoughts?

I found pvc fittings work with hose, usually the street fittings will go inside the hose, then you can use a clamp.

Thanks, that might work. Have to find the right OD, could maybe cut some grooves in it. The seacock lives in the closed position on this particular boat and is only opened when in use so I might consider it, but it's far from my first choice.

Is what you are really saying is that you have been down this road and you couldn't find what I can't seem to find?

I replaced the 60mm hose from the holding tank to the out valve (gravity fed). The new hose was very stiff to make a 90 and I found a street 90 that fit perfectly. I assume the same is true for other hose sizes.

Alternately, it should be pretty easy to source PVC barb-MPT fittings for each end and use a PVC reducing coupler to join them.

Re: 1-1/2" x 2" Hose Reducing Barb?

If you have a typical modern seacock with female pipe thread on top, why not just use a 2" to 1-1/2" bushing and a regular 1-1/2" hose barb?

Here in the US I have found Tractor Supply to have a good supply of fittings in that size.

Or, if for some reason hose-hose is easier/better/required and you just want a better setup than existing, you could get a reducing barbed hose coupler:
