A Southbend Range 3998-1 Gland Nut keeps the draw-off valve properly sealed for steady, leak-resistant performance.
The gland nut secures and compresses the valve packing so the draw-off assembly can maintain a controlled seal during operation. Its 3-inch configuration and threaded construction are important because they provide the proper fit and pressure needed to reduce leakage and support reliable valve performance.
The gland nut may need replacement if the valve begins leaking, loses sealing pressure or no longer tightens securely during use. Physical signs can include worn threads, cracking or corrosion and environmental signs may include moisture buildup, dripping around the valve stem or residue collecting near the fitting.
