Customers are mixed about the fit of the sporting goods. Some mention that it fits perfectly, while others say that it's slightly undersized and won't work on more rigid hoses. The measurements are useless, and the build quality seems good, but the fitting is too small to fit a 1.5 hose.

5.0 out of 5 stars Excellent for canopy tarp drain for rain

I'm using these as rainfall drains for the roof of a canopy tarp and they work near-perfectly. The only caveat is the diameter of the barbed tube, which is not grabbing my vinyl hose very tight. I can't tell if it is the barbed tube or the hose that is the culprit.

I replicate my grandson's wife's dog as a planter and used it to relieve water after rain. To drain standing water to prevent rotting out the planter box! It worked just as I planned! Well satisfied with it!

5.0 out of 5 stars Replacement for a missing fitting
Reviewed in the United States on August 4, 2023
Size: 1.25" 1-1/4"Style Name: 01-PackVerified Purchase
Needed to modify this fitting in order for it to work for my application. The original outside flange broke off but that fitting made a right angle turn once it went through the hull. It was a blind hole with no access on the inside of the boat without major cuts. Since this was a drain of a compartment above the waterline I just modified the fitting and glued it in place. Looks good and works fine.

Would be better if the flat end had a head that allowed it to be held with a wrench while tightening.
