This Five Oceans thru-hull is polished with AISI 316 stainless steel marine grade which shines like a beauty, not to mention durable. It's great for the marine environment. This product does not include a gasket.
Tapered Pipe Thread is commonly found on the ends of pipe, nipples, and fittings (i.e. couplings, elbows, tees, etc.). Note: Sharply angled threads are very critical to joint being tight with no leaks. Thread sealant or tape is typically required to complete the seal.
We take enjoyment in the products we make and guarantee the buyer that all Five Oceans products are ready to handle the extreme conditions of the open sea or terrain. However, we also know things can happen that's why we've got you covered for a year.
