A250 Standard Light HP Cylinders

Minimal weight. Minimal windage. Maximum reliability. Maximum longevity. Navtec standard cylinder rods are made from 316 or Nitronic 50 stainless steel. Tubes, lower clevis and caps are made of black hard-coated aluminum. Cylinder bores are specially polished for longer seal life. Navtec cylinders represent the highest standard of performance worldwide. Standard, Long, Flattening Reef, and Custom versions are available. Stainless Steel cylinders with 316 stainless construction throughout are also available. Titanium componentry is optional.
Due to the wide variety of Upper Ends Fittings commonly used, Standard (A250-SE) and Long (A250-LE) Cylinders are sold without them. Upper End Fitting Options include the Standard Aluminum Jaw Ass’y (A251-01-A), SS Jaw Ass’ys (H120), Lashing Eyes for Spectra Line (G703), Adjustable SS Turnbuckle Eyes (D540), Adjustable SS Turnbuckle Eyes w/ Toggle (D530) as well as a variety of Custom Options. Flattening Reef Cylinders (A250-FEinclude the A251 Aluminum Jaw Ass’y as Standard.

Navtec A250 Light (LE) High Pressure Cylinders have been in production for over 40 years and are designed to be more reliable, more durable, more easily serviceable, and have a longer lifespan than any others on the market. Most originals are still in use today. See Owner’s Manuals.

Carbon Wrap Cylinders

While beautiful in their own right, Navtec Carbon Wrap Cylinders are often used with the A950 Carbon Fiber Superyacht Vang. A thin Carbon veneer tube is applied to an A250 Cylinder providing the same Carbon finish and maintaining the style aesthetic of the A950 Carbon Fiber Superyacht Vang throughout the vessel.
