Review NAVTEC Series Integral Hydraulic Backstay Adjuster Cylinder New Seals

The Navtec IA7-17 and ITA7-17 Integral Hydraulic Backstay Adjuster Cylinders are engineered to provide reliable and efficient sail trimming solutions for sailboats. These cylinders are part of Navtec's Integral Backstay System, which eliminates the need for external hydraulic hoses and cylinders, resulting in a cleaner and more streamlined installation.

The IA7-17 and ITA7-17 are designed to fit boats with backstay lengths ranging from 17 to 20 feet (5.2 to 6.1 meters). The cylinders feature a rugged, one-piece, machined, and anodized aluminum body, which is both lightweight and strong. The cylinder boasts a robust, marine-grade stainless steel piston rod and a high-performance, double-sealed piston, ensuring a long service life even in the harshest marine environments.

The seals on these Navtec cylinders are designed to provide a perfect, leak-free fit. The piston rod seal is a labyrinth-style, self-aligning seal that eliminates the need for adjustment or maintenance. The cylinder head seal is a precision-machined, O-ring-style seal that ensures a tight seal and easy installation. Both seals are made of high-quality materials that can withstand the rigors of continuous use in a marine environment.

The IA7-17 and ITA7-17 cylinders are also easy to install. They come complete with all necessary mounting hardware and require no additional plumbing or hydraulic hoses. The cylinders can be mounted directly to the boat, and the hydraulic ram can be connected to the backstay tensioner or other control system.

In summary, the Navtec IA7-17 and ITA7-17 Integral Hydraulic Backstay Adjuster Cylinders offer a robust and efficient solution for sail trimming. Their integral design eliminates the need for external hoses and cylinders, ensuring a cleaner and more streamlined installation. The cylinders feature a rugged, one-piece aluminum body, a high-performance piston, and reliable, double-sealed piston rod and cylinder head seals. With easy installation and a long service life, these cylinders are an excellent choice for any sailboat owner seeking to improve their sail trimming capabilities.
