About Hose & Pipe Fittings

Boat Hose Fittings

Boat plumbing fittings cover a wide variety of applications aboard. From thru hulls to raw water strainers, boat sink drains and vented loops, marine water pipe fittings options are extensive. Fabricated of bronze, plastic, marelon, and stainless steel the choices of fittings means doing your homework and purchasing just the right fitting for your project.

What is the best material for marine plumbing fittings?

Boat pipe fittings are available in bronze, brass, marelon, nylon, stainless and heavy-duty plastic. The best material is most likely one that matches your current plumbing, especially when joining fittings together. Complete removal and replacement of marine plumbing fittings offer the option to upgrade to higher quality material. Keep in mind that heavy bronze fittings may add unwanted weight to your vessel and depending on the application might not be necessary.

Marine plumbing is a pretty complicated business.

In through the hull, out through the transom. Loops, Y-valves, strainers, and exactly when do you need to add a seacock? Defender carries a full line of every fitting for every project, but perhaps a quick-connect fitting system would provide an uncomplicated weekend project for the average DIYer. One thing is for certain before any marine plumbing project begins, double-check the hose fittings required and have them all on hand and ready to go!

Marine hose fittings come in all shapes and sizes.

Marine hose fittings are available in 90-degree and 45-degree elbows, nipples, and couplers join different pipes together while end caps do just that, end the pipe. Tank fitting kits are available for full removal and replacement of all plumbing coming in and out of the water and holding tanks. Seacocks, thru hulls, strainers, and raw water manifolds are a bit more complicated while pipe to hose fittings and marine pipe reducers are pretty straightforward. Double-check your application and fitting shapes and sizes then get shopping at Defender Marine!
