A Southbend Range 4221-1 Gland Nut secures the draw-off valve assembly to maintain a tight fit and dependable function.
The gland nut secures and compresses the valve packing so the draw-off assembly can maintain a proper seal during operation. Its precisely sized construction matters because it keeps the valve aligned, reduces leakage at the stem area and supports dependable flow control under repeated use.
The gland nut may need replacement if the valve becomes harder to tighten properly, shows inconsistent sealing performance or could allow seepage around the stem during use. Physical signs can include visible wear, cracking or thread damage and environmental signs may include moisture buildup, mineral residue or corrosion forming around the valve area.
