Good quality and was an exact replacement for the aged and deteriorated fitting that was removed.
the threaded portion before the bend was not long enough for my installation
Excellent product for the $.
This was perfect for setting up a thru-hull spout for a bilge pump (Tsunami 1200) in my royalex whitewater canoe. Drill a 1 3/8" hole in the hull, install this fitting, run a 1" hose to it, and hit the water!
Just as described. Measurements were right on the money which made for a perfect fit. Will definitely go to T-H Marine Supplies for any future fittings I may need.
