Install the
sight glass gasket into the
sight glass ferrule, followed by the
sight glass lens. The
tri-clamp gasket can then be placed on top of the sight glass ferrule such that it seats in the ferrule groove. This assembled portion can then be placed onto a tri-clamp ferrule, ensuring that the tri-clamp gasket is seated in both grooves. The two ferrules are then clamped together using the tri- clamp. The tri-clamp should be tightened to 25 in-lbs of torque. Be careful not to under tighten or over tighten the tri-clamp as either can result in unwanted conditions including a leaking connection or gasket intrusion. The Sight Glass assembly includes a tri-clamp weld ferrule to use if an existing tri-clamp connection does not exist. If the ferrule is not needed for the application, discard, or re-use as needed. Due to the number of unique situations where a tri-clamp weld ferrule could be added, it is highly recommended to consult a fabrication and welding specialist for the welding operation. Cleaning The VL-3A sight gauge can be Cleaned-In-Place (CIP’d); however, it will also require periodic inspection to ensure the gaskets maintain a proper seal and no leaks are present.
