Product ID: 05116595 – Gland Nut

Description:
This component is a gland nut designed for high-pressure waterjet cutting systems. It is a threaded fastener used to compress and retain sealing components, such as O-rings, backup rings, or packing seals, within a valve body, cylinder, or high-pressure fitting.

Applications:

• Used in waterjet cutting machines to secure and seal high-pressure components such as intensifier cylinders, check valves, shut-off valves, or plunger assemblies.

• Installed over a gland or seal carrier; tightening the gland nut compresses the seals against a mating surface to create a high-pressure dynamic or static seal.

• Suitable for both pure water and abrasive waterjet systems where leak-proof operation under extreme pressure is required.

Features:

• Constructed from high-strength, corrosion-resistant material such as stainless steel or hardened alloy steel to withstand repeated tightening and extreme internal pressures.

• Precision-machined threads ensure proper fit with corresponding female threads on valve bodies or cylinders.

• Designed with appropriate wrench flats or hex geometry for reliable torquing during assembly and maintenance.

• Engineered to apply uniform compression to underlying seals, preventing extrusion and blowout under ultra-high pressure (typically up to 60,000 psi or higher).

• Resists galling and thread deformation even after multiple installation and removal cycles.

Maintenance:

• Before removing a gland nut, fully depressurize the waterjet system and follow lockout/tagout procedures.

• Clean the gland nut threads and mating surfaces thoroughly during each service to remove debris, old seal material, or corrosion.

• Inspect threads for signs of damage, galling, stretching, or corrosion; replace the gland nut if any deformation is found.

• Check the wrench flats or hex corners for rounding; damaged driving surfaces can lead to improper torque application.

• Apply a thin layer of high-pressure compatible lubricant to threads before reassembly as specified by the equipment manufacturer.

• Tighten the gland nut to the specific torque value listed in the equipment service manual; over-tightening may damage seals or threads, while under-tightening may cause leaks.

• Replace the gland nut if it shows any signs of cracking, stress corrosion, or previous overtightening.

• When replacing seals, always use a new gland nut if recommended by the manufacturer, or inspect the existing nut thoroughly before reuse.
