I believe I received the wrong part for the Lomart Sand Filter (Spectra2, model 1-2165-089)
that I ordered on Aug. 10. Order 89277.
The exploded filter components view for the Spectra2 at your website shows the
hose adapter as a larger (2 inches) threaded piece (No. 35) that screws into the
valve assembly and to which you attach hoses at the smaller end (http://lomart-parts.com/1-2165-089.htm).
What I received looks like a hose adapter to connect two hoses. It has no
threads and is about the same size at each end, only slightly tapered at one
end. The O rings I ordered that go with it are the correct ones for what the
exploded view shows -- the larger screw-in hose connector.
I've enclosed photos of what I need and what I received.
Please let me know how you wish to handle this problem

what I received -- the hose adapters I received instead

original connector -- this is what I need and what the diagram shows as No. 35

Where it fits.....................
