Shark bite is one popular manufacturer. They are typically metal fittings and considerably higher cost compared to the plastic alternative made by Watts. Both are significantly more expensive than the barbed fittings and crimp.
In residential settings one of the significant cost advantages is the "home run" topology. Since the tubing is flexible, elbows and tees are no longer needed like they would be on a copper installation. Similarly the time associated with assembly is reduced considerably. One continuous pipe from source to destination. The bend radius and methods of securing the tube/pipe in place makes the "home run" a bit more challenging on board a boat. A home run using a flexible drinking water hose product like that made by Shields or Trident is my choice. The flexibility coupled with the freeze protection and durability all and up to a quality and lasting solution. Use barbed brass fittings and clamps. It sounds like this was Bob Boyer's solution. Trident #162, 163, 164, or 165 https://tridentmarine.com/product/trident-reinforced-pvc-hose-164162/ https://www.westmarine.com/WestAdvisor/Selecting-Marine-Hoses This is the lowest price per foot I could quickly find... And it is more expensive than PEX. https://www.amazon.com/dp/B004CR4OP4/ref=cm_sw_r_cp_apa_i_zONuCb7PXTPM7 Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Wed, Jan 30, 2019, 11:00 PM Rick Brass via CnC-List < cnc-list@cnc-list.com> wrote: > I’ve done a couple of plumbing and landscaping projects using PEX tubing. > Lowes and probably Home Depot sell a fitting for PEX tubing that uses small > teeth where the fitting engages the tubing and requires no special tool. > You simply push the fitting into the tube.
