Bob’s Plastic Thru-hull fitting
Requires 2 per set of hoses.
The “Bob’s” style unit is a threaded unit with a large plastic nut that tightens from the inside, VS other styles that use 3 screws to attach from the outside of the boat.
This style is better as it is only drilling the one hole for the hose. However if you can not reach the inside to tighten the nut, the other style might be preferred. We have both styles here.
**Only bulk hose can pass through this fitting. Pre-made hoses with end fittings cannot pass through. If hoses already have fittings, will need to remove them to install these and then reattach hose fitting
