Navtec Series 7 integrals can be identified two different ways. There is a plaque on the cylinder with a model and serial number, but very often those are no longer readable. If you cannot read the part number on the plaque then you can use the below table to identify the integral and seal kit by cross referencing the Clevis Pin Diameter, and Piston Rod Diameter. It is highly recommended that calibers or micrometers are used to take accurate measurements. Offshore Spars is not responsible for mis-measurement and/or selection of seal kits.
