Happy so far.

The thru hull fittings went in as planned. The critical issue is to get a good seal outside and inside for a permanent watertight condition. One disappointment was on one of the fittings the barbed end was not fully round but I hope the flexible hose will compensate for that condition.

I replaced a plastic thru-hull fitting for a bilge pump in a mahogany 1961 Chris Craft and it improved the looks incredibly.

Used these to replace thru hulls on older GW. Outstanding product and highly recommended. Tool works well for 1"" but not as good for. 1 1/2"". Hard job working one handed. Rapid shipping and excellent support

Description is incorrect, Fitting OK

The description is incorrect for the SS thru hull fitting. It's not designed to accept a seacock or valve directly. Not enough threaded shank. It's designed to attach the hose directly. It appears Groco does not offer a full threaded SS hull fitting, just brass. Its still a good fitting. Lucky I was able to use it on another project instead on returning it.

There is a groove cut for an o-ring wigh wasnt included . Its not truly a 1/2 "" but a sleeved like 5/8"" so I ended up not even using it.

A: The actual measurement of the fitting is right around 1.3"" so the closest hole saw would probably be 1-5/16"" (1.3125"").
